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.
