Halogen Light Temperature

Color temperature See the appendix 3.

Halogen light temperature. If you lower the filament temperature by changing the voltage with a dimmer you will get less light output and dimmer lights. Halogen lamps glow at a higher temperature 2800 to 3400 kelvins with a whiter colour than other incandescent bulbs. It is brighter than the incandescent cool white.

If youre after a road legal option the Philips WhiteVision is known as the first road legal intense white light with a colour temperature of 4300K. The halogen gas does it job by catching atoms from the filament which are driven from surface by the high temperature. Incandescents operate at about 2800 K while halogens get up to 3400 K.

To reduce the heat emitted by regular incandescent and halogen. A halogen lampis a bit better. As a reference the color temperature of candlelight is about 2000K and bright sunlight is about 6000K.

According to the Wikipedia online encyclopaedia a 100 watt bulb is 21 efficient. LED lamps on the other hand are available with all color temperatures for a wide variety of applications. This process combined with their small size causes halogen light bulbs to produce more heat than any other light.

However this requires bulbs to be manufactured from fused quartz rather than silica glass to reduce breakage. Electric Lamp Company Tungsten Halogen Lamps. Direct sunlight has the equivalent of 4800K.

See the PhET simulation below for a comparison. Higher filament temperature will increase the ratio of visible light which belongs to rather short wavelength band of emission from a halogen lamp. For lamps with a color temperature of over 5000K the reference is natural daylight which also has a CRI of 100.
