I seen Piaa lights for the Fusion, in H11, they are known as a high quality bulb, and at 4000 kelvin they aren't a bad colour either. Has anyone tried these bulbs, they don't appear to be too heavily coated like other cheaper bulbs out there. A friend of mine sells the PIAA bulbs in his shop and has had good luck with them in the past in other vehicles. I may end up running these.

Let us know how you make out! Anyone interested in the Sylvania Silverstars for your highbeams H7, go to Pep Boys. They are on sale right now. Get a copy of the coupon off their site. Twin pack H7 $34.99 - $5.00 coupon = $29.99 - $10.00 Pep Boys rebate= $19.99 - $ 5.00 Sylvaina rebate (off Sylvania website) = $14.99 for the twin pack (any sales tax will be on the $29.99.)

Please explain, so before I put them in I can decide to keep them or not.

I'll give it a shot.

Take two 55W halogen bulbs.  Bulb 1 has clear glass, and bulb 2 is the same but covered with a "super-duper ultra-white" blue (or dichroic) film.  Which bulb is brighter?  Assume both lamps are attached to the same power supply @ 13.8V.

A. Bulb 1.

B. Bulb 2.

For extra credit:

C. Clear Silverstar bulb made by OSRAM Germany.

Hint:  Which bulb type are the manufacturers forced to use in their new vehicles?  What happens when you cover a light source with anything not perfectly clear?

In North America, for the brightest light, we're pretty much stuck with option A.  Too bad we can't legally get option C.  It's really tragic that too many desperate drivers try option B, mostly (I guess) due to false advertising.

EDIT:  I just looked at

http://www.xtremewhite.com/ORD-Light~bulbs-PIAA-PIAA~Bulbs-no-23935-1-1-1-1.cfm

...and that page contains some of the worst marketing BS I've ever seen.  "100W output from a 55W bulb"  :lol:

...or this: "PIAA light bulbs manufactured with PIAA technologies save energy, provide less heat therefore lengthen the life of the car light bulbs."

Priceless.

yeah I don't know how they get this 55w bulb produces same light as 110 watt b.s., lots of companies make that type of claim and I just don't see how it can be true.

I seen some PIAA bulbs today and they didn't have that really blue coating on them like some of the cheaper bulbs out there, if they were coated it was very slight. They are very expensive bulbs as well, probably 3 times the price of the average aftermarket bulb.

Just the tip is blue, the rest is clear. The lights are still kind of yellow and aren't much better than stock. Especially for the price.

You're "test" is good, up until the fact that companies such as Sylvania Silverstar (USA, not Osram Germany) use higher levels of inert gasses (like Xenon) and more tightly-wind the filament to increase light output to make up for the filter. Output in lumens is close to or exceeds clear-bulb levels, but at the price of longevity. That's why Sylvania Silverstars only last a year or two.

100W = 55W refers to the color temperature of the bulb, not the light output. Look at a candle and it appears yellow. Look at a 100W bulb and it appears white. It's marketing to ignorance, but those of us that know what they mean laugh a little inside.
