Quartz Light definition

A quartz light is a kind of light that is quite bright.  Inside its quartz envelope is a tungsten filament.  When in use, quartz lights can become very hot.  If oil from one’s hands gets on the bulb, the bulb may blister and explode; obviously, it is never a good idea to touch the bulb with one’s fingers.  The color temperature of the light is usually 3,200K.  Also known as a tungsten or halogen light.
