What is the difference between d2s and D3S bulbs?

D1 and D2 types of light bulbs operate on 35W 85V AC current. These bulbs contain heavy metal mercury. Newer HID bulb designs (D3S, D3R, D4S, D4R) that are in production since 2009 contain no mercury and are more environmentally friendly. These lights require special ballasts that differ from D1 and D2 types.

Which is better xenon or HID?

Unlike most HID lamps that do not reach full brightness until they are hot enough, Xenon lamps do not need to warm-up, and provide instant bright light. Xenon lamps simulate daylight better, and the light is more natural compared to other HID lamps.

Can you touch an HID bulb?

They actually run a lot cooler than tungsten, that’s why their running rating is 33watts, and touching them shouldn’t do any harm. If you’re worried, then a good clean with alcohol, maybe using one of those lintfree soft papers sold for camera lenses should clean them up.

Which is better 35w or 55w HID?

You will get about a 50% brightness increase by going from a 35-watt ballast to a 55-watt ballast. So the 8,000K HID bulb will go from 1,000 maximum lux to 1,500 maximum lux at 25 feet, but the color will shift to a 6,000K color. Just because your HID bulb says 10,000K or 12,000K does not mean that it is brighter.

Is 6000K or 8000K brighter?

While it might seem a bit odd, the 6000K LED headlights are brighter than the 8000K headlights – and there’s science to back this distinction. Light intensity is measured in Kelvin units, which are abbreviated to K.

What’s the difference between D2S and D2R bulbs?

The difference between D2S and D2R is that D2S HID bulbs are designed to be used in a projector headlight application, and a D2R type is made for a reflector application – such as in worklights and some driving lights. You can easily identify them as the D2R has a painted shield onto the glass, whereas the D2S doesn’t.

What is the difference between D2R and D4R bulb?

First is the voltage required to operate the bulb: D2 bulbs operate at 85V while D4 bulbs operate at 42V. Secondly, D4 bulbs are newer more environmentally friendly versions of D2 bulbs; D4 bulbs are mercury free.

Why do you wear gloves when changing headlights?

Sometimes it is instant, and sometimes it can last a few weeks, but touching the glass with your bare hands will always cause the light burn out quicker. To keep this from happening when you change a headlight bulb, you should wear a pair of vinyl or latex gloves and to avoid touching the glass of the bulb.

Do HID lights fade over time?

Do Xenon HID Bulbs lose brightness and dim over time? Yes, over time a Xenon HID bulb can lose some brightness and colour intensity as they begin to age. We find that branded bulbs like Osram Xenon HID Bulbs degrade a lot less than cheap unbranded Xenon HID Bulbs.
