Hi, I am just wondering why/how when someone touches a light bulb with their fingers how it will decrease the life expectancy of the lamp assembly (what causes it).
When replacing any halogen bulb, do not touch the glass envelope. The salts in your skin oils penetrate and weaken the glass. The bulb not only has a shorter life, but when the bulb dies the filament doesn't merely burn out, but rather the bulb envelope shatters. The light bulb industry calls it a "non-passive failure."
