Item Halogen lamp LightningHID Remarks Bulb structure HID contains no filament. It consists of tungsten filament filled up with inert gas. The components that make up an xenon light source are quartz arc chamber, electrodes, chemistry, mercury, xenon gas and a quartz sleeve. The quartz arc chamber contains the plasma discharge. Electrodes provide the starting and ending points for the plasma discharge. Bulb general quartz UV cut quartz UV cut quartz avoids UV exposure to people and materials while allowing maximum visible light passing through. Luminous type with electricity passing through tungsten filament activate xenon gas by means of electrodes Tungsten filament generates more heat resulting in higher temperature which would be broken easily all in sudden. HID remains light on as long as there is xenon. It would only gradually dim out when xenon gas amount becomes less and less. Ignition HID generates more energy. Luminous intensity 1000 Lumen 3500 Lumen Higher lumen provides higher visibility. Luminous cover area short and narrow beam longer and wider beam LightningHID covers 2 times more area resulting in more safety   Beam LighningHID beams more brighter, more longer and more wider. Colour temperature (K) 2000-3000 3500-12000 5000-6000K is as close as dayight which eliminates visible fatigue. Life time (Hour) 350 3500 Longer life time results in more economic. Power consumption (W) 55-100 35 HID reduces about half of electricity and thus, results in less fuel consumption and better car performance.。

Summary   LightningHID shines 3 times brighter, covers 2 times more area and lasts 10 times more, but consumes only half of power versus halogen lamp.

Unlike halogen lamp, HID has different colours according to different colour temperature. Color temperature is a simplified way to characterize the spectral properties of a light source. Standard unit for color temperature is Kelvin (K). The color temperature of light refers to the temperature to which one would have to heat a "black body" source to produce light of similar spectral characteristics. Low color temperature implies warmer (more yellow) light while high color temperature implies a colder (more blue) light. Colour temperature is not a measurement of brightness. Higher/lower colour temperature does not imply higher/lower brightness.

LightningHID provides a wide variety of bulbs with colours from 3500K-12000K. The most popular colours are:   Colour temperature (K) Colour Diagram Light penetrating power General name LightningHID 3500 yellowish white Poppy Yellow Higher light penetrating power 4300 whitish yellow Sunflower 5000 white Icy White 6000 white with 5% blue Iceberg Blue 8000 white with 10% blue Cool Blue 10000 white with 20% blue Blue Diamond Lower light penetrating power 12000 white with 30% blue Sapphire Other colour gold Bullion Gold - purple Violet green Emerald pink Panther Pink   When looking at the light coming directly out of HID headlights, some of them possess a bit of blue or purple hue with colour temperature 8000K, 10000K or even higher. High colour temperature does not help for higher brightness. However, some people recognize blue or purple as the expensive and elegant look characteristic of HID's. Low colour temperature, for example, 3500K is mostly applicable for fog beam specially designed to use during bad weather condition. With the extreme light penetrating power, the 3500K xenon bulb would give the driver a more clear vision on the road. For comparison, most halogen headlights have a color temperature around 3200K which gives them a "dingy" yellowish appearance compared to HID's. The disadvantage of high colour temperature is that it leads to low light penetrating power passing through rain and fog. Using such high colour temperature HID should be carefully considered especially in those areas where there are frequent poor weather condition.   What Colour temperature? 4300K yellowish white, , 6000 crisp white light with delicate to moderate blue tint.   I have been driving with HID Xenon’s now for many years and as you may have guessed I have tested every combination of Kit, bulb and colour. The following is a summary of my findings (objective as I bought light meters to measure the actual light outputs) and recommendations (both objective and subjective), which most customers agree with.   OEM is 4300K and without a question gives the most amount of light. I have tested dozens of bulbs and compared them all to a Philips D2S bulb as a reference point. The difference between colours and manufacturers is really quite shocking.     The best 6000K bulb produced 15% less light than the Philips 4300K - while the worst 6000K bulb was a dreadful 70% less. That said, our bulbs being the best ones with 15% less light in measurable terms, actually produce a very white light with a slight blue tinge to look at. For every day driving this really is a more pleasant light than the yellowier 4300K.   If you’re after the coolest looking Xenon’s with amazing performance then 6000K is my recommendation   If you are after the most amount of light on the road then I recommend the 4300K - which is a yellowish white 4300K whilst having NO blue and for the purists we do have some 4300K bulbs also.   If you want the blue look like the OEM factory fit Xenon’s then please remember that the blue is not produced by the bulb, but by the reflector/projector lenses. Refraction spilt the colour of the light like a Prism if you remember that experiment from Physics. When you get up close the bulb is actually 4300K with a yellow tinge. 8000K bulbs or higher are not the answer - they produce very little light – up to 70% less than the 4300K and the Police do not like them.

	6000K has an approximately 2900lm output, which is 3x the light output of the traditional halogen light and slightly less light output compared to the 4700K. Although it has a bit lesser light output, it emits pure whiter light with a slight tint of blue.
	8000K has an approximately 2500lm output, which is about 3x the light output of the traditional halogen light and slightly less light output compared to the 6000K. While it has a bit lesser light output, it emits bluer light than the 6000K. This is one of the most popular of all color temperatures by customer demand.
	10000K has an approximately 2300lm output, which is more than 2x the light output of the traditional halogen light. 10000K produces a deep blue light output approaching violet and the blue is noticeably deeper than the 8000K. This is the most popular color temperature by customer demand.
	12000K has an approximately 2000lm output, which is more than 2x the light output of the traditional halogen light. This color temperature puts out a deep bluish violet light and is deeper colored than the 10000K. It is for customer who are looking for the most extreme and most exotic looking light output.
