Fact

Factory zenon bulbs anyone recommend me some

Ozram cool blue or Ozram night breakers

If you're wanting factory OEM quality, then either Philips or Osram D2S bulbs are going to be your best bet. I'm pretty sure both manufactures produce an OEM 4300K colour and a 'whiter' 5500K / 6000K aswell, but being OEM quality they are quite pricey!

 

A lot of people (myself included) have used HIDs Direct for D2S bulbs. Much cheaper than OEM, and they've been serving me well now for well over a year!

Sorry I didn't read the xenon bit!

For the brightest possible d2s bulb,  then OSram nightbreaker unlimited.

 

About £90-110 for a pair, 

 

I got mine from Amazon a few months back,   which replaced my Phillips Ultinon (blue xenon d2s) bulbs.

 

 

The Nightbreakers are deffo brighter,   but they do cost a fair whack.

 

 

I've used cheapo Ebay d2s bulbs before,  and they aren't as bright,   and after a few months of use,  they seem to visibly loose their power too.

The Philips ultinons where bought to replace ebay bulbs.  Yes the colour was better than OEM,  but the power of the light wasn't as good still.

 

So in my experience,  the latest Osram nightbreaker unlimited are by far the best so far

Overenthusiastic marketing again. Yes, by all means buy either Osram, Philips, or GE for quality D2S lamps, but these Osram Nightbreaker Unlimited lamps do not emit any more light than factory D2S. In fact, they have lower colour temperature than Philips Vision Xenon (4600K), and marginally lower light output as well (Osram 3200lm, Philips 3300lm).

 

If it was my car, I would buy Philips Vision Xenon D2S, as they would result in best road lighting. Not sure what the price is though.

 

Initial HID light output specification was 3200 lumens at 4100K-4300K, if you see lower output from decent quality lamps it is because of the colour, e.g. GE burners from similar family start at 3200lm at 4200K white, down to 2500lm at 5100K daylight white, falling down again to 1750lm at 10000K crazy blue.
