HID Headlights
HID stands for "High Intensity Discharge". Becoming more popular on high-end cars, the light given from an HID 35W bulb is more than double the light from a 60W Halogen bulb. Xenon light is based on the gas discharge principle , where an arc of light is created between two electrodes within the glass bulb filled with metal salts and inert Xenon gas. So there's no filament.
Xenon bulb life is in the order of 4500 hours - three times the life of a Halogen bulb.
HID lights are powered at 80V, so a 'ballast' power unit is needed to power these bulbs. All Ballasts have under and over voltage protection as well as short circuit protection. All units are 100% waterproof.
NOTE! There is some dispute over the legality of aftermarket HID kits. The Department for Transport has said that in it's opinion the HID is not legal because they do not comply with Road Vehicle Lighting Regulations 1989 yet in the same statement they say "The UK cannot refuse to register a vehicle with a European type approval". It seems the jury is still out. Also, the HID kits we supply are "White", not toward the Blue esection of the colour spectrum. HID light output is measured in a "Colour Temperature" referred to as so-many "K". All our HID kits are of 6000K - which equates to Daylight at Noon. See the chart/explanation below (Source Wikipedia).
| Temperature | Source |
|---|---|
| 1,700 K | Match flame |
| 1,850 K | Candle flame, sunset/sunrise |
| 2,700–3,300 K | Incandescent light bulb |
| 3,350 K | Studio "CP" light |
| 3,400 K | Studio lamps, photofloods, etc. |
| 4,100 K | Moonlight, xenon arc lamp |
| 5,000 K | Horizon daylight |
| 5,500–6,000 K | Vertical daylight, electronic flash |
| 6,500 K | Daylight, overcast |
| 9,300 K | CRT screen |
The color temperature of the electromagnetic radiation emitted from an ideal black body is defined as its surface temperature in kelvins, or alternatively in mired (micro-reciprocal Kelvin).[2] This permits the definition of a standard by which light sources are compared.
To the extent that a hot surface emits thermal radiation but is not an ideal black-body radiator, the color temperature of the light is not the actual temperature of the surface. An incandescent light bulb's light is thermal radiation and the bulb approximates an ideal black-body radiator, so its color temperature is essentially the temperature of the filament.
Many other light sources, such as fluorescent lamps, emit light primarily by processes other than thermal radiation. This means the emitted radiation does not follow the form of a black-body spectrum. These sources are assigned what is known as a correlated color temperature (CCT). CCT is the color temperature of a black body radiator which to human color perception most closely matches the light from the lamp. Because such an approximation is not required for incandescent light, the CCT for an incandescent light is simply its unadjusted temperature, derived from the comparison to a black body radiator.
