The difference between xenon and halogen lights is the gas used in the light bulb. Xenon lamps use xenon gas, while halogen lamps use a gas from the halogen group. Iodine and bromine are the most common halogens used in lamps.
Halogen light bulbs are incandescent lamps containing a halogen gas instead of an inert gas in the bulb. Halogen bulbs are more efficient, give higher quality lighting and have a longer rated life compared to ordinary incandescent bulbs.
A type "T" halogen light bulb is a halogen bulb bearing a 'tubular" shape. Unlike other bulbs that contain argon or nitrogen gases in the envelope surrounding the filament, these longer-lasting bulbs bear gases from the halogen group that blend effectively with the tung...
To remove a halogen bulb, simply remove the light fitting from the ceiling, and take out the bulb. Make sure the electrical mains going to the light are off and the bulb has had time to cool down before touching the light.
Halogen light bulbs are changed like any other light bulb, but it is imperative that you do not touch a new halogen bulb with your bare skin. Leaving an oily fingerprint on the bulb can create a "hot spot" that causes the gas to leak and can shorten the life of the bulb...
In order to remove a halogen light bulb remove the heat guard and grasp the bulb. Turn counter clockwise, making sure it is not squeezed too tightly.
Touching a halogen bulb with bare hands can leave fingerprints, and these oily areas become hotter than the rest of the bulb, causing the bulb to burn out faster. A halogen bulb with fingerprints can burn out or explode within just a few minutes.
