| 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. |
