Hey, im in the market to finally upgrade to these lighting kits and have a few questions which i hope many can answer. I have Depo Gen 4 headlight assembly on my e36. Heres my questions:

1. which ones are better for everyday driving and will not piss off anybody by blinding on coming traffic or attracting the police.. 35W or 55W hid kit?

2. Colors: not looking for anything fancy just colors that give me the best lighting and throw for night driving: What is the best 'night driving' color choice for 35w and for 55w.

3. Which is more reliable, 35w kits or 55w kits, especially in winter or cold months.

4. bulb longitivity? would going 55w shorten the life of the bulbs/ballast?

thanks.

35W 4300k from Propr'one. 6000K looks better though.

+1 on the 6000K.

I don't think you'll be pissing off much drivers unless your headlamps are poorly aligned.

thanks for the replies. so looks like 35w kit

which color works best in fog/rain? 4300k? 5000k? or 6000k?

4300 works better in the rain. The higher (more blue) colours tend to be absorbed by the water.

I know about that all too well:( I have 55w 6000k's, they are damn bright in the dry and sexy. But in the wet they don't provide much lighting. they are still a lot better that stock though:P

a lot of lights are like this, I think mainly because the wet surfaces reflect the light away from you rather than reflect it back at you when it's dry. Think of it as being a mirror when wet.

everyone always thinks 6000k is good. *th-up*

I just prefer 6000K as a colour because it's not too blue, but not plain white. It's a good level. I even swapped out the OEM 4300's to 6000K, and I love it. It still looks OEM but catches your attention more.

4300K or go home!

If you have them installed correctly, and have adjusted your cutoff so that the light beam doesn't go into other drivers line of sight, the 55W kit is better, brighter, puts more light on the road, and will not blind anyone.

2. Colors: not looking for anything fancy just colors that give me the best lighting and throw for night driving: What is the best 'night driving' color choice for 35w and for 55w.
5000K. Enough blue that they will match A/E's, and not look yellow compared to ccfl's, or in pitted/worn housings, but not enough blue to get harassed/rice out the car/ get too much glare in wet conditions.


3. Which is more reliable, 35w kits or 55w kits, especially in winter or cold months.
The 55w kits technically have the same reliability ratings as the 35w. In my experience, their failure rate is exremelt low (lower than standard 35w, very close to failure rate of digital 35w ballast (slim) (~0.9%)).


4. bulb longitivity? would going 55w shorten the life of the bulbs/ballast?

Ballast, no.
Bulb, yes, but generally marginally so, depending on which kit you go with. Some manufacturers use 35w bulbs in their 55w kits. This will work, however, the manufacturing tolerances in 55w bulbs are smaller than they are in 35w bulbs. That, combined with the additional power running through them, can burn bulbs out sooner.

Most reputable HID manufacturers use 55w-specific bulbs in their 55w kits (myself included)

Just a note-
If you decide on a 55w kit, keep in mind that the higher power changes the appearance/temperature of the light.
The bighter light makes a 5000k bulb look more like a 4300.

I have a 35w kit for fogs, and a 55w kit for low beam, and the difference is noticeable.

Id recommend a 6000k bulb if your planning on running 55w and want the 5000k appearance.

^^that's not entirely accurate. Unfortunately, most people dont even know what a 6000K looks like.

Kelvin are a scientific measurement of light. If HID manufacturers produced products that were bang on, all brand new 6000K's would look like all other 6000K's, as 6000K is a specific colour. (assuming they were in similar housings)

Its generally true that on lower end HID kits, where 55w kits use 35w bulbs, that bulbs rated at 6000K will produce more white light, with the elements producing blue light proportionally making less like, therefore making them look whiter. If the 55w hid kit you purchase uses 55w specific bulbs, the colour should be whatever the bulbs were branded at.

There's other problems that have to do with light output in ellipsoids/projectors. Most ellipsoids white light out to begin with (colour coming out of the ellipsoid is whiter than the light coming out of the bulb, due to the refractive properties of the ellipsoid). This effect is increasingly noticable the more candlewatts a bulb produces. Since 55w hid's produce approx. 32% more light than 35w, they can also appear even whiter than their 35w equivalent would look in a given ellipsoid.

thanks guys for your insights. Ive made my decision and have ordered the 35w 5000k kit.

I just switched to 5000K's from the OEM, I'm sure you'll be happy with the 5000K kit.
