HID (Xenon)
The light as emitted by a light arc between two electrodes which makes the lamp insensitive to shocks and vibrations, providing a burn life up to 6000 hours. The Xenon lamps burn at 4200°K. Since this light color is closer to daylight color the captivity of the eye is better used and you as a operator will be less tired and get more done.
Xenon lamps have a very good luminous flux and will, including the control electronics, provide three times as much light as a halogen lamp. The good color rendering will enhance this experience and the light from a 35W Xenon lamp will for the eye equal at least that of three 70W halogen lamps.
The disadvantage of the Xenon lights is the high service cost once they need to be serviced, an operational voltage of 80V and a high inrush current. Low cost Xenon lights are often difficult to start in cold conditions and may interfere with the radio.
