Dichroic & Reflector Halogen Lamps

Dichroic halogen lamps are incandescent lamps with a reflector that reflects visible light while allowing infrared light to pass through, making them cooler than regular lamps.

How do dichroic halogen lamps work?

Dichroic halogen lamps use a filament heated to a high temperature to create light. Halogen lamps are fitted with a tungsten filament, which is sealed into an envelope along with a small amount of inert gas and a halogen such as iodine or bromine. This chemical mixture ensures that the filament burns out slower, making them last longer than other types of lamps.

The dichroic reflector in the light housing adds intensity to the white light while allowing the infrared light to pass through. This works to remove most of the heat from the lamp.

Types of dichroic halogen lamps

Dichroic halogen lamps can have different levels of intensity, colour temperatures, beam angles and sizes. You should choose the lamp according to the type of light you want the lamp to produce.
