They do not have a need in gas, typically the power of electric current, and they give out increasingly lesser amount of warm. It may look to be a down side in observation to their halogen analogues, yet much less heat leads to prolonging their efficient operation. The third choice is xenon (HID) light bulbs. The HID in their name suggests high-intensity discharge, meaning the popular property of such lamps - their exceptional illumination. In energy intake and warmth emission they take place between halogen and LED light bulbs.
They do not contain filament, but still use gas (xenon) to produce blinding white-hot light they are well-known for. Although they are available in a range of shades.

- 4300K for Xenon
- 6000K for LED
