Innovative Xenon Gas Discharge Technology (HID)

Unlike conventional bulbs, Xenon bulbs do not have a bulb filament. Rather, the light is produced using an electric arc. A mixture of the inert gas, Xenon, and metallic salts is enclosed in a glass bulb the size of a matchstick head. The light arc is ignited between two electrodes. A sophisticated electronic ballast is necessary for this process.

The high voltage of 20,000 volts necessary for the ignition of the light arc, is produced by a 3rd Generation ballast or in the base of the D1S Xenon bulb. The advantages of work lamps using HID Xenon bulbs in comparison with a 55 watt halogen bulb include the following:
• 2.5 times the luminous flux and at the same time 23% less power consumption.
• Increased luminance results in a brighter and larger illumination of the working area.
• Light spectrum is similar to daylight – for natural colour reproduction of the environment.
• Vibration-proof light arc instead of a sensitive breakable filament.
• Service life up to five times longer – reduced expenditure for bulb replacement.
• Constant brightness – independent of fluctuations in the current supply thanks to the electronic
power control in the ballast.

Note: To achieve optimum service life of the Xenon bulb (D1S/D2S), the angle of inclination measured from the horizontal position must not exceed +/- 35 degrees. Doing so causes the metallic salts to shift and inhibit a connection between the two electrodes at the time of ignition.
