Built-in lamp in a plasterboard wall. Lighting and spotlights for plasterboard ceilings

Interior design often includes structural changes to the ceiling. Gypsum board is a very popular material used for ceilings. It is used for various design options. This is either a solid suspended ceiling or relief ceiling structures. In any case, a gap is created between the main ceiling slab and the drywall. It is used under .

In any project, plasterboard lamps built into the ceiling are one of the best solutions for high-quality lighting. In some design projects, these light sources may be the main lighting instead of a chandelier. This article will tell you how to install LED spotlights for plasterboard ceilings, as well as what other light sources can be used in these structures.

Where to start?

Before starting work on upgrading the ceiling, it is recommended to make a preliminary design. It depicts the ceiling, the contours of plasterboard sheets, if any construction of them is provided, ceiling lights built into the plasterboard structure, and electrical wiring to power the light sources. It should be attached to the ceiling with clamping brackets on dowels, in holes drilled in the ceiling slab. Properly installed wiring uses a corrugated tube. If the base of the ceiling is made of wood, the corrugation is selected from metal. If the ceiling is concrete, it can be plastic.

In those places of the load-bearing ceiling slab, under which the mortise lamps will be located in the plasterboard, a loop is made from the cable. The location of the loop must coincide with the marking at the point for installing the light source on the drywall. It is best to drill small basic holes in the drywall for the lamps before attaching the sheets to the ceiling. This is more reliable than marking with a pencil or marker. After installing the electrical wiring, which is more convenient to carry out multi-core cable on the main ceiling, plasterboard is attached to it.

Applicable light sources

Spotlights very popular in both residential and office premises. Structurally, they are all similar, despite the fact that the light sources can be halogen and xenon lamps, as well as LEDs. Models for lamps are made as a reflector with a socket into which the lamp is inserted.

Typically, LED luminaires are equipped with LEDs to achieve minimal dimensions. They are built directly into the reflector or light diffuser. Many spotlights have almost the same diameter. The main differences are in their length and depth. Halogen and xenon lamps installed in ceiling lamps, should not heat the case more than 60–70 degrees Celsius. High temperatures are not good for drywall.

How big holes are made

Typically, installing spotlights in drywall begins with measuring the basic dimensions of the housing. For each of them you need to cut a mounting hole. To do this, you can use one of two special drilling attachments for an electric drill. The first one is a set of circular saws. A slightly larger blade is selected from the set to suit the diameter of the body.

Another device is a milling cutter on the rocker arm. It allows you to cut holes whose diameter is larger than the saws in the set. If you need to install large recessed lights in drywall, a milling cutter is the most suitable tool. These two electric drill attachments make it possible to quickly make perfectly round holes.

Set of circular saws and cutter with rocker arm

But if you don’t have a drill, you can do without it by using a short saw with a narrow blade. Before cutting holes, you need to make markings according to the template. The template can be selected from used rolls of adhesive tape, as well as any lids or boxes of suitable sizes and round shape. A template is applied to the places where the lamps should be installed in the plasterboard ceiling and outlined with a pencil or marker. This creates a cutting line.

If there is already wallpaper on the ceiling, before using the saw, the surface inside the hole must be cleared of it so as not to accidentally tear it. This is done by cutting the mounting knife along the intended line. Inside the resulting circle there should be a hole large enough for the saw blade to fit into. Using it, you can easily get a round hole with fairly smooth edges. Once installed, the recessed lights will cover them. But still, working with a saw requires a certain skill and accuracy. You should not move it back and forth with a large amplitude.

Connecting luminaires to electrical wiring

Then the cable is removed from the resulting hole. It must be prepared for connection to the light source.

After installing the housing, it’s time to install the wires. The best connection to pass through electric current done by soldering. Light source connectors are pre-prepared. Short wires are soldered to them, which will then be connected to the electrical wiring. Since this will also be soldering, the ends of the wires must be well coated with solder. Before connecting the wire to the electrical wiring, a piece of insulating tube made of heat-shrinkable material is put on it.

When installing the electrical cable cores, it is recommended not to cut them. First, the outer layer of insulation that covers both cable conductors is removed. The cuts are carefully made with a mounting knife on both sides of the middle of the loop. Then, from one incision towards the other, a longitudinal incision is made two to three centimeters in length. This allows you to grab the outer insulation and pull it off the wires, trimming as necessary. Then each of the two wires is folded in half. At the bend point, the insulation is carefully removed with a mounting knife to a length of 2–3 cm.

After this, the stripped core is folded in half so that it covers the end of the short wire that is soldered to the connector. After this, twisting is done. To make it more durable, it is recommended to use pliers.

The finished twist is prepared for soldering. To do this, it is moistened with an alcohol-based liquid flux to remove the grease film. After this, the twist is well soldered. A pre-prepared tube made of heat-shrinkable material is put on the finished twist. It is heated with a soldering iron until the required shrinkage occurs. A light source is then attached to the connector.

In our case, the installed device is a reflector with several built-in LEDs. The wires are laid in a niche between the drywall and the main ceiling. In this case, the installation of lamps in a plasterboard ceiling is completed by the final fastening of the reflector to the body with a special elastic bracket. This completes the installation.

Ensuring uniform illumination of the room and all objects and furniture located in it is possible only with the help of a distributed light source. Even the most sophisticated sconce installed in the center of the ceiling is unlikely to cope with this. After all, the light will come from one place, and as a result shadows will appear. To solve this problem, so-called spots are used - spotlights of small size and power, which are evenly distributed over the surface of the ceiling. They are intended for mounting exclusively suspended ceiling systems. It is quite easy to install spotlights in the ceiling with your own hands. It is important to take care of the configuration of the lighting system even at the stage of designing a suspended ceiling.

A little about spot lighting

By their design, spotlights, which are mounted flush with the suspended ceiling, have only a 30-degree lighting sector. But due to their compactness, they can be mounted quite tightly across the entire ceiling. To ensure proper illumination, the distance between rows should not exceed 1 meter, the distance from the lamp of the outer row to the wall should not be more than 60 cm. The figures are given for rooms with a ceiling height of 2.5 meters. The requirement is taken into account that the intersection of the cones of illumination from each spot be located at a height exceeding the bulk of the objects in the room.

Spot lighting can be mounted on any type of suspended ceiling. Installing spotlights in plasterboard is the simplest and most reliable option, but the installation process is no different in the case of ceiling cladding with plastic, aluminum strips or MDF, with several caveats.

Only installation of lamps in suspended ceiling must be carried out by craftsmen and installers. This is due to technological features material and the fact that it is necessary, using special equipment, to secure dense inserts made of heat-resistant plastic in the places where the lamps are installed. These inserts also prevent the material from stretching. In all other cases, installation can be done independently.

What is needed for installation

The following elements will be needed from the material:

1. spotlights;
2. lamps;
3. supply wire;
4. terminal blocks or sleeves for connecting wires;
5. insulating heat shrink, electrical tape;
6. switch.

installation of a standard ceiling spot

It is advisable to select lamps of the same type for each type of lighting. According to the type of design, the lamps themselves are purchased in the required quantity. It is important to strictly check the presence of a reflective layer along the cone at the base of the base for incandescent lamps and technical specifications in accordance with the requirements for the lamp. For suspended ceilings, 40 W lamps are used; more powerful ones will significantly heat the suspended ceiling material and can lead to structural damage or even a fire. Halogen and LED versions of lighting elements are selected according to the power and spectrum of the light produced.

The wire is selected depending on the material from which the suspended ceiling is made. So for drywall, which is a fire-resistant material, a regular two-core or three-core wire VVG-2(3)x1.5 is suitable. For materials such as MDF or plastic, it is necessary to select a fireproof version of the RKGM wire. The wire must be soft, that is, each core is represented by many small veins united under one insulation.

To connect wires and connect lamps to them, you can use special terminal blocks, which are sold at any hardware store. However, the bolted connection is serviceable. You will need to check the tightness of the clamping bolts at least twice a year. Otherwise, at the point of contact, the terminal blocks and wires may begin to heat up and char. A more reliable and durable option is fixation using copper or tinned copper sleeves.

It is necessary to protect the connection points using electrical tape or using a special heat-shrinkable tube to insulate the supply wires.

Installation procedure

The entire process of installing lamps in the ceiling can be divided into the following stages:

• lighting planning;
• wiring to the installation site of the lamps;
• forming holes for them;
• connection;
• consolidation and verification.

Why so simple task divided into several stages? This is due to the fact that each point is best performed on at a certain stage formation of the ceiling itself.

Planning

It is very important to decide in advance, even before covering the ceiling, how to place the lamps on the ceiling. This is especially true in cases where the suspended ceiling is formed with several levels. Each level should be separated into a separate lighting circuit, and light sources should be distributed accordingly, based on the independent use of these circuits. Do not forget that the distance between the lamps should be maintained within a meter from each other, the distance from the walls should be 60 cm. It is important to distribute the lamps so that their installation location does not fall on the installed frame elements. That is, the holes for them should be spaced at a distance of 25-30 mm from the edge of the hole for the lamp to the nearest frame element. Otherwise, the profile of the frame may prevent the lamp from being secured using its latch.

When distributing spotlights, it is also necessary to take into account the presence and location of chandeliers, sconces and other decorative elements on the ceiling and walls. When used simultaneously, spotlights can be moved to the sides. Or divide the lighting circuits with spotlights for areas near other light sources and the rest of the room into separate switches.

Wire distribution

It is best to distribute the wires at the stage of forming the frame of the suspended ceiling and secure them to the frame in advance so that when drilling holes for the lamps, you can get the wire loops and make the connection. As a last resort, the wire is supplied to the first of them, and for all subsequent wires they are threaded from hole to hole. The disadvantage of the latter option is the impossibility of securing the wires to the frame, and they will simply lie on the surface of the suspended ceiling material.

With normal advance distribution of the wire, it is enough to lay a two- or three-core cable along the optimal route to all installation locations of the lamps, leaving a loop of 10-15 cm of bent wire at each point. Fastening to the frame should be done using plastic ties, but not tightly and with a slight sag of the wire, without tension. This will prevent damage to the wire due to thermal changes in its length.

After this, you can begin covering the suspended ceiling.

Forming holes for lamps

You can finally decide on the position of the lamps only after the ceiling is completely sheathed. During the design, the moment of placing the spots at a distance from the frame elements was already taken into account. Now you should also take into account the location of the seams between the elements of the suspended ceiling; this is especially important when installing lamps in a suspended ceiling covered with plastic or aluminum. If the lamp is placed at the junction of the ceiling elements, then it should be moved to the middle of one of the strips.

The holes are drilled using a special wood bit, which also drills recesses for the socket boxes. In this case, perfectly straight holes are obtained; this option allows you to effectively fix the lamp in drywall. The diameter of the holes must be selected in accordance with the dimensions of the devices used. It should be 3-4 mm smaller than the outer diameter of the front part of the lamp, but larger than the dimensions of its inner part. The most commonly chosen size is 60 or 75 mm.

Important: Remember that once you drill a hole, it cannot be moved, so once again make sure that its location is correct.

Typical connection diagram for ceiling lights

Connection

After all the holes are drilled, the loops of the previously laid wire are pulled out. Or, two wires are laid from hole to hole, starting from the outermost one, to which the supply wire is connected.

Important: All connection work is carried out only when the appropriate wire is de-energized.

The loops on the laid wire are cut along the bend and exposed. To connect each lamp, two small wires 10-12 cm long are used. Having exposed a 10-15 mm wire on each side, the short wires (leads) are clamped at one end into the corresponding terminal on the lamp, and the second edge of the wire is twisted with the power cable. The connection is observed using markings on the lamp: L – phase, N – zero, PE – grounding.

Nowadays lighting devices are used not only for their intended purpose. With the help of lighting you can transform the entire room. Even the simplest single-level ceiling will become a real masterpiece and will attract admiring glances if you choose the lighting fixtures wisely. Can be used different lamps into a plasterboard ceiling, including combining several types of them. But before you start experimenting with lighting, it won’t hurt to learn about the features of selection and installation various types lamps

Lighting design

They begin to work on lighting even during the creation of a suspended plasterboard structure. First, electrical wiring is laid over the frame; the wires lead to the places where light bulbs will be installed in the plasterboard ceiling in the future. Before sheathing the frame, holes are made in the sheets of material for the lamps.

The disadvantage of plasterboard ceilings is that after the sheathing is completed, access to the wiring will be impossible. To alter the system or carry out repairs, the drywall will have to be removed. Therefore, before covering the ceiling, you need to decide on the type of lighting (general, spot, complex) and the type of lamps suitable for the chosen solution. Then you need to decide where the lighting fixtures will be located and connect the wires to these places.

Some types of lighting require special conditions. For example, LED strips Can only be installed in multi-level ceiling structures with a partially open area between levels.

It is permissible to use several types of devices simultaneously. For example, spotlights and a chandelier, or an LED strip with spotlights. Combinations can be different, so it won’t be difficult to come up with interesting and effective lighting. Properly selected, it can transform a room, highlight the interior, and make the room visually larger. Lighting options can be seen in the photo.

Spotlights

Spot lamps for plasterboard ceilings are ideal. Many people generally install suspended ceilings only to use spotlights for lighting. They can be located at any point on the surface, so the design possibilities in this case are very wide. For example, a room is divided into several functional zones, lighting one of them more brightly and leaving the other in twilight. A large number of lamps, controlled by a special switch, makes it more functional - for example, you can adjust the brightness of the lamps, turning on not all, but only some devices.

LED spotlights for plasterboard ceilings come in two types:

• non-rotating (fixed rigidly);
• rotating (make it possible to change the angle at which the flow of light is directed, thereby highlighting exactly that area of ​​​​the room that needs enhanced lighting).

Chandeliers

Ceiling chandeliers– traditional lighting fixtures, they can be found in many apartments. And today they are the most popular light source. Install them in the center of the ceiling. There are two ways to mount chandeliers.

Compact and lightweight devices are attached through plasterboard to special embedded profiles. You cannot attach a chandelier directly to the casing, since the material may not support even a lamp that is not too heavy. If you need to attach a chandelier specifically to drywall, then it is advisable to choose the lightest model, and carry out the fastening itself using a special butterfly dowel, which will distribute the load over the sheet area.

LED strips

Often used led light bulbs for plasterboard ceilings. With the help of such lighting you can get interesting and beautiful lighting effects. But you need to keep in mind that LED strips cannot serve as the main source of lighting - their radiation is too weak to allow reading, sewing and any other work that requires intense light. If you don’t want to install other types of lamps on the ceiling, you can put a floor lamp in the room.

LED strips have a long service life and many different lighting effects. From them, make a simple one-color glow of the ceiling structure, as well as running waves, smooth color transitions and even color music.

Single-color plasterboard ceiling bulbs can only emit one color, but the light intensity can be adjusted. The greater the density of LEDs per linear meter of strip, the more intense its glow. But at the same time, the more of them on a strip, the more expensive it is, however, given the long service life of the light bulbs, such a purchase is quite profitable. To connect the LED strip you need a transformer.

The most expensive are multi-color RGB strips. For them you need to install a special control controller. Such tapes connected to this device are capable of creating light effects of different colors. To do this, you just need to enter the required program into the controller, and the tape will begin to play with all the colors of the rainbow, depending on the taste of the owner.

Plasterboard ceilings can be made even more beautiful if you try to choose the appropriate lighting option. Now there is nothing complicated about this - there are a variety of lighting fixtures on the market that can advantageously complement the interior and add sophistication to the room.

After installing plasterboard ceilings, you need to install lighting fixtures. What lamps can be used? To illuminate the room, you can use LED or fluorescent lamps. You can also use LED lighting to illuminate the room. Before installing lighting fixtures on a gypsum ceiling, you need to make slots of the required size in the sheets.

A plasterboard ceiling with lighting allows you to bring unusual creative ideas to life. To illuminate the room, you can use point light sources or lamps. If you like extraordinary solutions, you can mount a chandelier or make hidden lighting.

When installing the backlight, observe the following rules:

• Observe polarity.
• Cut the tape only in special places.
• If you need to connect more than 3 strips, give preference parallel circuit connections.
• Before gluing the tape, check its functionality.

During installation work, make sure that light sources do not fall into the place where the profiles are located. If necessary, change the profile markings or move the lamp slightly to the side.

Do-it-yourself plasterboard ceiling with lighting: step-by-step installation diagram

It’s easy to install lighting on a suspended plasterboard ceiling with your own hands. You need to start installation by making a design sketch. The drawing will help you plan your work and calculate the number of components needed.

Scheme for installing lighting on a plasterboard ceiling:

1. First you need to attach a starting profile.
2. We attach the hangers. We attach a frame made from the main profile to them.
3. We fasten the frame using connectors.
4. Next, you need to sheathe the structure with plasterboard sheets.
5. Connect the LED strip cord to the contacts on the power supply.
6. Check the voltage of the tape and power supply.
7. If the voltage is normal, stick the tape to the ceiling.

If you are installing LED lighting on a plasterboard ceiling, connect no more than 3 coils. Otherwise, the paths along which the current passes may not be able to withstand it and will ignite.

LED spotlights for plasterboard ceilings: features and advantages

LED recessed bulbs are the most commonly used because they are relatively inexpensive and long lasting. In addition, these lamps emit little heat. Thanks to this, plasterboard tension sheets do not overheat and are not deformed.

Advantages LED sources Sveta:

• Energy saving. Such light bulbs consume significantly less electricity.
• The service life reaches 60,000 hours of continuous illumination.
• The lamps do not emit ultraviolet light.
• fasten led lamps much simpler than halogen ones.

Some models LED lamps are able to change the color of the section. Such devices are somewhat more expensive, however, such a lamp allows you to change color scheme premises. Typically, such models are used to decorate a living room or children's room.

Built-in lamps in a plasterboard ceiling: selection criteria

Recessed luminaires provide uniform lighting around the entire perimeter of the room. This device helps to achieve a visual division of the room into zones. Recessed lights can be bright or dim.

Recessed luminaires can have a rotating or non-rotating mechanism. Lamps of the first type allow you to change the angle of light emission. Non-rotating ones have a rigid mount and cannot change the lighting angle.

To install built-in lamps you can use:

1. Incandescent lamps.
2. Energy saving light bulbs.
3. LED lamps.
4. Halogen light sources.

There are open and closed lamps. The first ones are used to decorate a living room or children's room, since such devices are not protected from moisture. When installing lighting in the kitchen, it is recommended to choose closed lamps, because they are completely protected from moisture and steam.

We install the box on a plasterboard ceiling with lighting

A box with lighting helps not only to diversify the design of the room, but to hide communications and electrical wiring. Installing such a structure is a simple process. In order to make the box yourself you will need pliers, a CD-60 profile and a grinder.

Before you start, you need to paint the pipes. This will help prevent rust from appearing on them. After the paint has dried, apply a coat of primer to the pipes. You also need to eliminate any holes in the ceiling.

Installing a box on a plaster ceiling:

• Screw the UD profile to the wall.
• Fix the brackets to the ceiling.
• Attach the edge of the plasterboard sheet to the CD-60 profile, which will lie directly against the pipes.
• Cut the ends of the hangers and bend them.
• Attach the CD-60 profile to the hangers.
• Lay down sheets of drywall.
• Make a niche and decorate it with LED strip.

Do-it-yourself hidden lighting for a plasterboard ceiling

Making a plasterboard ceiling with hidden lighting is quite difficult. Before installation, you need to make preliminary markings. Remember that hidden lighting involves the use of light bulbs that do not emit much heat. It is best to use LED bulbs. In turn, halogen light bulbs do not fit into a hidden niche.

Hidden lighting is only suitable if the ceiling height is large. Otherwise, it is not recommended to use this design.

It is necessary to make hidden lighting in the following sequence:

1. First you need to draw a line along the wall to which the supporting profile will be attached.
2. Attach the UD profiles using screws. The spacing between attachment points must be at least 45 centimeters. You cannot use wooden choppers, as such a structure will be fragile.
3. Secure the CD profiles using self-tapping screws.
4. Route the wiring.
5. Cover the structure with plasterboard.
6. Putty the seams. If desired, apply paper tape to the joints.
7. Attach the lights. This completes the installation.

Dimensions of holes for spotlights for plasterboard ceilings

Before you install spotlights in the ceiling, you must decide on the size of the hole. Usually the dimensions of the hole for the lamp are indicated on the packaging, however, it is advisable to measure it yourself. Permissible deviations are 2-3 millimeters. If you cut a hole that is too large, it is advisable to replace the sheet.

The most common hole sizes for the lamp:

• 30 millimeters.
• 40 millimeters.
• 150 millimeters.

After you have installed the spotlight, do not forget to install the thermal ring. This will help avoid overheating of the canvas. In addition, these products provide mechanical strength to the structure.

Installing lamps in a plasterboard ceiling: step-by-step instructions

Regardless of what lighting options you use, the installation of lamps must begin by making holes of a suitable diameter. Also, before starting work, you need to turn off the power to the wires.

Lamp installation algorithm:

1. First, route the wires through the holes.
2. Take the lamp and secure the wires going to the socket in a special block.
3. Install the lighting fixture housing.
4. Insert the light bulb into the socket.
5. Put on the decorative trim.

When connecting the lamp, adhere to safety regulations. When connecting, follow the markings. “PE” is grounding, “L” is phase. The letter "N" is a phase.

Installation of spotlights in a plasterboard ceiling (video)

It is easy to install spotlights on a ceiling made of plasterboard sheets. You need to start the installation with marking and choosing the optimal lighting fixtures. It is recommended to use LED strips. Incandescent lamps are a good alternative. If you have high ceiling, you can make niches for hidden lighting.

Spotlights for plasterboard ceilings (photo)

Today, spot lighting is used very often in houses and apartments. This is due to the ease of installation of the products, as well as their inconspicuousness on the ceiling, which in no way spoils the interior of the room. Next, we will talk about how to correctly install spotlights in drywall with your own hands, providing step by step instructions and a visual video lesson.

Installing spotlights in a plasterboard ceiling has many advantages, namely:

• It’s not complicated; even a novice electrician can handle it;
• takes very little time (fix 1 piece no longer than half an hour if everything is prepared);
• high-quality lighting of the room, especially if you use economical ones;
• The light bulbs are hidden in the ceiling without spoiling the interior of the room.

We draw your attention to the fact that it is recommended to use LED lamps, because... they have a fairly high luminous flux and service life. In addition, these products allow you to save more than 30% of electricity!

Preparatory work

To begin with, the cable is pulled in a protective corrugation through a structure of profiles to the approximate location of installation of spotlights in drywall. The wire itself runs from the main switchboard to a distribution box fixed in the room itself. You can find out more about this event in the article:.

From distribution box it is necessary to lead along one wire route to the installation site of spotlights in the plasterboard ceiling. To do this, it is recommended to use one of the following conductors: 3*1.5; or . To select the most suitable conductor, it is recommended to carry out. Typically, a 1.5 mm copper wire is sufficient for a lighting line.

We draw your attention to the fact that many self-taught electricians are trying to make their work easier and connect the lamps in order from one line, simply connecting the products to each other with cables. We do not recommend using this installation method, because... in this case, the loads will increase noticeably and “fall on the shoulders” of the very first connection point with the home electrical wiring. As a result, an overload may occur, leading to spontaneous combustion of the wiring and a short circuit.

When the wiring is separated, you can proceed to the main process.

Main process

So, installing spots in drywall includes the following steps:

1. Preparing the walls
2. Connecting the product
3. Control check

Let's consider each of the stages of installing a spotlight in more detail.

Preparing the walls

In this article we consider installation work if the ceiling is plasterboard. All you need to do is cut the grooves in the ceiling. Grooves are called seats for installing a lamp. They can be square or round, depending on the shape of the product.

In one case or another, to install a spotlight in drywall you will need the following materials and tools:

• electric drill;
• crown for working with wood;
• thin and indicator screwdriver;
• terminal blocks;
• pliers.

First of all, be sure to turn off the power in the network and check its presence using an indicator screwdriver (it can be used in an outlet or on contacts connected to the ceiling). Next, drill a hole in the drywall. The diameter of the crown must necessarily coincide with the diameter of the body (maximum spread no more than 3 mm).

We draw your attention to the fact that it is possible that the hole you have chosen will end up on the frame made of profiles. In this case, you will only ruin the ceiling, because... Installing a spotlight under drywall will not work. To avoid such a problem, we recommend that you mark in advance the places where the profiles are installed, or use them to check their presence in the right place.

Connecting contacts

When the hole in the drywall is cut, you need to find the input wires that you brought from the junction box and connect them to the lamp. The most effective are vago terminals or regular terminal blocks. Their advantage is good fixation and insulation of the cores, as well as high installation speed. In addition, using these connectors, you can fasten cores of various sections and materials.

After connection, it is necessary to fix the spotlight in the plasterboard ceiling. To do this, we clamp the spring legs with our hands and carefully insert the body into the groove. There is a so-called method: fix the legs with wire in advance (as shown in the photo) and after installation, cut the wire with wire cutters. It is reasonable to use this trick when fragile ceilings and expensive products are used, because... If you fail to secure it the first time, the paws may damage the ceiling material.

After the body sits in seat, you need to screw in the light bulb, if it is threaded, and proceed to check.
