A halogen light bulb is filled with a gas that conducts heat much better than a vacuum. For this reason, her balloon is heated to a high temperature. If it is contaminated with grease, the glass may soften and break.
Instructions
Step 1
Choose the right replacement lamp to replace a burned out lamp. A lamp with a mirror can be with a base of type MR-11 (GU4) or MR-16 (GU5.3), and lamps of types G4 and G5.3 differ from similar ones with the letter U in the designation by the absence of a mirror. Do not install a lamp in the luminaire for which it is not designed.
Step 2
The most convenient halogen bulbs are equipped with built-in conical mirrors and protective glasses. To replace a lamp of this type, de-energize the lamp, wait for it to cool (even if the lamp being replaced has burned out and has cooled down for a long time, neighboring bulbs can heat up its body), then remove, if necessary, the parts that cover the lamp, then pulling it out of the holder … There is no need to unscrew it, since pins are used instead of a threaded base. Insert the new lamp with the pins into the socket, make sure it is firmly in place, reassemble the lamp in the reverse order and turn it on.
Step 3
Some halogen bulbs are equipped with conical mirrors but do not have protective glasses. They require more careful handling. When replacing, hold such a light bulb only by the reflector, not touching the bulb at all. If you do touch the flask, degrease it with alcohol (do not use other substances!), Wait until it is completely dry (it may take half an hour) and only then turn it on. If you do not degrease the flask, it will burst, and if you do not wait for the alcohol to dry after degreasing, it will catch fire. Otherwise, the method of replacing this type of lamp is the same as described above.
Step 4
Lamps without conical mirrors at all are the most inconvenient. Take such a light bulb out of the package without touching it with your fingers - only through a layer of fabric. Install it in the same way. If during the installation process you touch the lamp bulb with your finger at least once, degrease it and wait for the alcohol to dry as described above.
