The halogen gas reduces wear on the filament, so tungsten-halogen bulbs last longer than incandescent bulbs. The bulb of a tungsten-halogen light is made of quartz, because quartz has a high melting point. If glass were used, it would start to melt when the bulb got hot. WebIncandescent bulb are black body emitters. Basically, something is heated enough so that it radiates most of the power put into it. The black body radiation spectrum is well known, … crystals for decoration
