Tungsten vs. Standard Incandescent

Tungsten Halogen Standard Incandescent
Halogen gas causes the evaporated tungsten to redeposit on the filament. The high pressure within the bulb slows down the deterioration of the filament Tungsten is deposited on the walls of the bulb reducing light output. Over a relatively short time the filament gets thinner until it finally breaks.
High color temperature and 100 CRI. Their light contains more blue and green than a standard bulb causing the halogen light to appear whiter and brighter. Low color temperature and 100 CRI casts a warm light that provides good color rendition of human skin tones.
Uses a low voltage system that operates efficiently at lower wattages than line voltage systems. Produces light by heating a solid material until it glows. Most of the energy consumed is given off as heat, resulting in low LPW (lumens per watt) performance.
Produces large amounts of light from a very small area causing excellent beam control. Poor beam control.
