Halogen lamps have an internal chemical reaction that recycles evaporated tungsten back onto the filament, increasing their lifespan and maintaining the clarity of the bulb. Capable of operating at a higher temperature than standard gas-filled lamps of similar power, the lights produce a higher luminosity and colour temperature. The generally small size of halogen lamps permits their use in compact optical systems for projectors and illumination.
