Frequent Answer Question

1. HID / Xenon Technology:
XENON HID lamps do not have a filament. Instead the light is created by an electrical discharge between two electrodes in an air tight tiny quartz capsule filled with xenon gas, mercury and metal halide salts. This improves durability as road vibrations can cause damage to coil lighting technologies. These light sources also produce a blue-white light that is safer because it is closer to natural daylight. The color temperature is approximately 4200 K compared to 3200 K for halogen. The increased light output from a 35 watt XENON HID lamp is approximately 80% more light then a 55 watt halogen bulb. The XENON HID system will also draw less power from your vehicles electrical system.

2. Temperature:
Color Temperature is a measurement in Degrees Kelvin that indicates the hue of a specific type of light source. Many people believe the misconception that colour temperature is a rating of the brightness of the bulb or HID kit. This belief is completely false. The reality of the matter is that the higher the colour temperature, the less useable light output you will obtain. A perfect example would be a black light. This light has a colour temperature of approx 12,000k and has almost no useable light or lumens output. Higher K kits such as 7000k, 7500k, etc. have been manufactured for individuals that are more concerned about the actual colour output of their lights as opposed to the actual useable light output they produce.


Chromaticity and Colour Temperature


XYZ trisimulus values and the associated Yxy colour space form the foundation of the present system for numerical colour notation. The concept for the XYZ tristimulus values is based on the premise that all colours are seen as mixtures of these three primary colours. By defining the colour matching functions of a standard observer, the Commission Internationale de L'Eclairage (CIE), an international organization concerned with light and colour, provided the basis for colorimetry in 1931. The Tristimulus values XYZ are useful for specifying a colour, but the results are not easily visualized. The two-dimensional colour (x,y) diagram is taken from the Yxy colour space, in which Y is the lightness (and is identical to the tristimulus value Y) and x and y are the chromaticity coordinates calculated from the tristimulus values XYZ. The CIE x,y chromaticity diagram for this colour space is shown. In this diagram, achromatic colours are toward the center of the diagram, and the chroma or saturation increases toward the edges.

Colour Temperature (Tcp)
A black body (perfect radiant body) is an ideal object that absorbs all energy, changes its colour from red through yellow to white as its temperature increases. The absolute temperature T (K) of the black body is referred to as the colour temperature and colour by a locus (black body locus).

The above diagram is sometimes used to indicate the colour of a light source. Correlated colour temperature is used to apply the general idea of colour temperature to those colours that are close to, but not exactly on the blackbody locus. For instance, a light source which has a colour difference of 0.01 in the green direction (Duv) from a black body which has a colour temperature of 7,000K is indicated as having a correlated colour temperature of 7,000K + 0.01 (uv unit).


:3.: What is Xenon Light?

The xenon bulbs supplied with the HID kit are micro-discharge bulbs filled with a mixture of primarily xenon gas and other inert gases, creating a superior, bright, white light so close to Sunlight that it looks blue. This special bulb has no filament like a halogen bulb, but the light is created between the two electrodes in a xenon bulb and is like none other.

This high precision HID system places the bulb in the exact correct position inside the headlamp. No mounting rings or loose parts are used to fit the bulb as they may bring problems. These loose fittings have created alignment problems in the first generation kits.

At first you might think this is not dramatically important but it is very important due to a fact that only a small portion of the overall bulb emits the light. All systems are as mentioned earlier "bulb beam corrected".

:: More light output?

A 35 watt HID lamp produces up to 3 times=300% of the lumens at the light source when compared to a conventional standard 55 watt Halogen lamp.

:: Whiter Light and Greater Driver Comfort?

Good visibility contributes to driver confidence which promotes relaxed, safer driving. Drivers can benefit from fitting HID Conversion Kits in their vehicles, since the white light stimulates driver concentration and makes night time driving less tiring. In addition, the HID system also delivers a marked contribution to road safety in the event of limited visibility due to weather (rain, snowfall) conditions. This is a must for safer driving.

:: Why was Xenon Light developed?

At least 60% of all traffic accidents take place in poorly lit conditions. And the older the driver, the more light required for seeing better during night driving. Brighter lighting by xenon light means most importantly, better road safety and less strain on the eyes.

:: Greater Visibility and Road Safety

While driving at night, there is nothing more important than being able to see where one is going. HID lights help in overcoming severe driving conditions by providing between two to three times more light than halogen lamps. This higher light output is put to very good use, improving both light intensity and light distribution on the road, thereby widening the field of vision for earlier recognition of people and objects. An additional benefit is that the brilliant white light is reflected much better by road markings and signs which makes for more confident driving in bad weather conditions and at night. The difference you can se below.


:: Lower Power Consumption

A 55 watt Halogen lamp draws a constant 10 Amps, while an HID lamp in steady state draws in 3-4 Amps (50-60% less power). As a result of lower power consumption, less heat is dissipated by the HID lighting systems and more power from the engine. Additionally, you will be doing your part for the environment: less power consuption means less waste.
An HID lamp will last four to five times as long as a halogen lamp. The lamp will have a life of at least 2,000 Hrs. For most people, this translates into the life of the vehicle and probably the life of the next vehicle as well.
