After about 1.5 years now has left the service of the two H7 bulbs. The vitreous is neither deformed nor has he changed color, no difference to a new lamp observed. This week appears in a newspaper, a new car review of H7 lamps and the White Hammer has done it again in 2nd place, only the Bosch Plus 90 H7 was rated better, but at twice the price. I use the lamps in an Audi A4 and has even found it works wonders, nachzubiegen small wire hanger. If the lamp that is stuck in its holder, it seems to work well with the life. Had me at the time the purchase date (09/2009) written on the box and think these are 17 months acceptable.
However, I think the critics at the color right from White Hammer there is not much to see in direct comparison the lamp significantly yellower than competing products. But that is a matter of taste, on the practical test seems to have no influence.
Strong buy recommendation, what I'll do now again. :)
