Replacing a light bulb in a luminaire does not require serious skills. But even in this case, certain difficulties may arise associated with the design of suspended ceilings and spotlights. For this reason, you should figure out how to replace an LED bulb in a spotlight.

Types of bulbs used
The incandescent lamp is the most famous type of lighting fixture. It consists of a bulb with a thread inside. When an electric current is passed, it heats up to 3 thousand. degrees and starts to glow. The advantages are low price and mass character. The disadvantages are high energy consumption. The incandescent light bulb also gets very hot on its own..
Halogen lamps are more efficient. They differ from ordinary incandescent lamps in that the bulb is filled with halogen gas vapors. This significantly increases the service life of such lamps. Their cost is slightly higher than the price of conventional incandescent lamps.
Fluorescent lamps consume even less energy than previous ones at the same luminosity. Compact appliances of this type, coiled and using a common base (E 14 and E 27), are known in the market as "energy saving lamps". The most significant drawback is the presence of hazardous mercury vapor. LED light sources are a promising solution that can replace older types. They are distinguished by the longest service life and the lowest energy consumption.
The choice of a specific type depends on the conditions of use. Halogen lamps are great for kitchens and rooms. They provide an optimal balance durability, cost and energy efficiency. LED bulbs give bright light and consume very little energy, but they are distinguished by the highest price.
Types and methods of fastening
There are three types of this mount., which determines how to replace the light bulb. Here they are:
- With the help of a latch and a two-pin base (designation examples - GU 5.3, MR 16), it is most often used for spotlights. In this case, the light bulb is simply inserted into the socket and snaps into place.
- With latch and two-pin base that can be rotated 90 degrees (example - GU 10).
- With conventional threaded base (E14, E27). It is used less often than the two listed above.
Light source replacement steps
First, you need to get the luminaire by removing the retaining ring with which it is fixed in the ceiling. To do this, you need to carefully pick up the antennae, take out the ring and put it aside, as it will be needed for re-installation. Then, depending on the type, you should carefully pull out or unscrew the bulb from the socket, holding it with your free hand. Regular and halogen bulbs simply twist out. If it collapses, then you should collect the fragments, and then unscrew the base with pliers, making sure that the cartridge is not damaged. In this case, it is also necessary to choose the correct size of the base.
Before installation, it is necessary to correctly determine the power and operating voltage of the lamp in order to ensure the desired level of illumination. It is necessary to check the data of both lighting devices and their packages, since, for example, there are LED lamps with a GU 5-3 base, designed for 12 and 220 volts. The power of the new source should be the same or slightly less than that of the old one. Otherwise, the luminaire may overheat, and the power supply provided by its design may burn out. Do not handle the bulb of halogen lamps with dirty hands - this significantly reduces their service life.
After a successful check, you can insert or screw the lamp into the socket. Then you should install the spotlight in its place. After that, you need to take the retaining ring, squeeze its ears, insert the ends into the grooves and release. Making sure that the lamp is securely fixed, you can supply electricity to the house and turn on the light.
Security measures
Before carrying out work, turn off the electricity supply in the house. A wall switch, if the electrical wiring is mistakenly routed, may open not the phase, but the neutral wire, which will lead to an electric shock during removal and installation.
The work site must be comfortable and safe. You cannot change the lamp on unstable benches and stools, for this you should use a high-quality factory stepladder. All procedures must be carried out very carefully so as not to damage the ceiling, the lamp itself and its wiring.
So replacing bulbs in false ceilings and spotlights - this is not as difficult a job as it seems.
