In Reply to: Re: Replacement headlights- Xenon bulbs??? posted by Steve B. on February 26, 2000 at 14:00:46:

wagner bulbs are made by philips? that's very interesting. i guess federal mogul, the company who owns the wagner brand, must sub-contract their lighting products.

anyway, philips does have its own line of bulbs called blue vision. this can be picked up at your local k-mart. there are also a line of bulbs with the brand name narva (a subsidiary of philips) which are suppose to be exactly the same as philips blue vision. these are available at some speed shops. osram-sylvania also has a line called cool blue. these can be picked up at automotive stores like kragens and pep boys. then there are piaa super whites available at most speed shops and a variety (too many brands to list) of cheaply made korean bulbs.

well, i'm been an active poster over at the philips automotive lighting forum for about a year now. so i've been following it pretty closely. the consensus there is that the osram-sylvania cool blues are whiter than the philips blue vision. next, is that osram-sylvania cool blue and piaa super whites are very similar in color output. this makes osram-sylvania cool blue (about $25 a pair) a better deal than piaa super whites (about $65 a pair). as for the korean bulbs, they usually have the more attractive light color but output on the ground is a lot worst. also with these bulbs the bulb life is very low and you run the risk of the bulbs exploding sometimes (happened to me).

i currently run osram-sylvania cool blue 9006 55 watters. no trouble so far. the color is whiter than stock, but still not as white as i want since i still see a lil hint of yellow. light output on the ground is about the same. the color temperature for the osram-sylvania cool blue 9006 is 3500. a regular halagen bulb is about 3200. piaa advertises 3800, but this is the rating for their h4 super white bulb. the color temp for the piaa super white 9006 is unknown. h.i.d. has a color temp of about 4200.

in conclusion, i guess the osram-sylvania cool blues are an improvement over stock, but i'm still looking for something better. well, hope this helps you out a little. oh yea, most of the brands that i have mentioned, claim to use a small amount of xenon gas.
