H7 bulb info
H7 bulb info
I gleaned this from a post I found on another site. http://www.clubtouareg.com/forums/f4...ral-31736.html
Take it for what its worth.

Any of the blue-glass "extra white" bulbs are an absolute nonstarter as far as seeing better is concerned. Sylvania Silverstar/Ultra, PIAA, Hoen, BlueVision, CrystalVision, TruView, Nokya, Polarg, etc. -- all a scam. Such bulbs produce significantly less light than even a standard bulb, so we'll start our comparison with standard bulbs.
Osram Silverstar, Narva Rangepower+50, and Philips VisionPlus are all "Plus+50" H7 bulbs. Philips Xtreme Power and Osram Night Breaker are both "Plus+80"/"Plus+90" bulbs. They are, as a class, the best 55w H7s you can buy. But, Osram offers (and I stock) an even better option with higher output and longer life. Here is the comparison (figures at 13.2 volts):
Standard H7:
55w, 1500 lumens, 500 hours
H7 ultra "Plus+50" (any brand):
55w, 1580 lumens, 225 hours
H7 Xtreme "Plus+80" (Philips) or "Plus+90" (Osram):
55w, 1620 lumens, 200 hours
H7 rallye+65 (Osram only):
65w, 2100 lumens, 500 hours, obvious choice.
The extra 10w is of no consequence as far as electrical power or heat --
those 80w to 100w bulbs are a different story, and they produce less light
and have a shorter lifespan than the Osram 65w item.
Philips Ralley 80W H7 bulb
Produces 100 lumens less than the Osram 65w, has a much shorter lifespan, draws more current and produces more heat. Lose/lose/lose/lose deal.

I have been looking at some of the early posts on this forum and some are hilarious now. Silly questions and even sillier answers. It would be a pity if the plug was pulled on these gems.
I was looking for the guy who posted one damning post on his Crossfire and either sold it or committed suicide. Hilarious, well, not if he killed himself.
