What is HID bulb ?
HID xenon bulb is a micro discharge bulb filled with a mixture of noble gases including xenon gas and mercury metal helitde salt.

What is the rated life of these xenon lamps ?
Depending on the lamp ,average - 3200 hours .
That means that 50% of these lamps can burn out before the Rated life and 50% can burn out after the Rated life and it does not mean that every lamp will last at least that long.

How easy it is to install these bulbs ?
They are all direct replacement bulbs and mount just like your original equipment bulbs. Most bulbs can
be replaced without tools in just a few minutes, but still we recomend to do replacement job in specialized
service cetrer

What is Kelvins (K) ?
Many people think that the higher is the colour temperature, than brighter is the lamp. This is not true. The color temperature is purely a scale to measure the color of the light output.The reality is that the higher up the scale lamps are than less bright they become, for example 4300K lamps are approximately about 10% brighter than 6000K. If you want lighting performance the 4300k HID lamps are the best, but in our opinion 6000K has the best and most attractive light output.

Degrees K = ONLY COLOR A basic unit of thermodynamic temperature (color temperature) used to measure the whiteness of the light output. The higher the number is, the whiter the light is. When over 5000K the light begins to turn to blue as daylight.

Available kelvins:
4300k - a white light yellow tone - 3600 (lm)
6000k - white light - 3400 (lm)
8000k - a white light with a blue tone - 2600 (lm)
10000K - blue light - 2400 (lm)
12000K - light blue violet shade - 2000 (lm)



What is Lumens (lm) ?
Lumen= BRIGHTNESS The international unit (SI) of luminous flux (quality of lights). For example, a dinner candle produces about 12 lumens and a standard 60-watt incandescent bulb produces 830 lumens. The higher the number is, the brighter the light is.
Color (K) and Lumen (lm) chart :

4300K - 3600 (lm)
6000K - 3400 (lm)
8000K - 2600 (lm)
10000K - 2400 (lm)
12000k - 2000 (lm)

What bulbs to choose for better visibility ?
More lumens (lm) - A better visibility.
I would recommend 4300k or 6000k bulbs but
even the light bulbs 12000K visibility will be
2x better than 55w halogen bulbs.

What should I do if I touch the bulb ?
If you have touched the bulb, remove these oils with alcohol and a very soft cotton cloth .

What decreases life of HID bulbs ?
Probably the number one reason is lamps running with non approved ballast. It does not matter how good the lamp is if the ballast characteristics are not OK the lamp will die prematurely.

Turning bulb on and off without neccesary cooldown. Turning it on more than 3 times an hour seems to reduce life according to datasheet.

Burning in the wrong position or plane. This creates over heating both of the internal components in the lamp but also at the pinch. The biggest failure across lamps as a whole is airleak. In the HID lamp you have very high pressure and temperature, if these are direct wrongly to the pinch the lamp will fail. Both Philips and Osram recommends horisontal (+/- 10 degrees) burn positioning.

Handling. They are a delicate product which have not been designed to be handled. They are very much fit and forget. You can risk damage either to the burner or to the UV shield or both. This damage can be either physical or by contact depositing oils and acids from your skin on the glass.

Headlight housing not according to specs of the D2 bulb. Bulb vibrations caused by loose retaining mechanism, or bulb getting too warm simply because housing is too small and do not get adequete cooling.

History of HID
First time xenon headlamps were introduced in 1991 as an option on the BMW E32 750. This first system used an unshielded, non-replaceable D1 burner. The AC ballast was about the size of a building brick.

The first American-made effort at HID headlamps was on the 1996-98 Lincoln Mark VIII, which used reflector headlamps with an unmasked, integral-ignitor burner made by Sylvania and designated Type 9500. This was the only system to operate on DC; reliability proved inferior to the AC systems. The Type 9500 system was not used on any other models, and was discontinued after Osram's takeover of Sylvania. All HID headlamps worldwide presently use the standardised AC-operated bulbs and ballasts. Current-production burner categories are D1S, D1R, D2S, D2R, D3S, D3R, D4S, and D4R.
