I am happy with Philips Vision Plus that I installed on both '00 E430 and '94 Lexus LS400 since April 2001. Both sets are still working on both cars. Only APB had his Philips VP burnt out in less than six months and he is upset about the short life of the Philips VP.
I am buying the H7 Navra Ultra High Output to see if it really generates the 2100 lumens that Daniel Stern claims in his web site. If it does produce that much light for only 65W, then it may have shorter life span compares with standard bulb. Is it worth $60?
