Right, I think it was overboost.com that did a test on these 'blue' bulbs, they were so bad that one example even put out 50% of the light of a normal H4 bulb.
They used a lightmeter and tried it in a car at different distances. Very interesting reading. It was mainly aimed at the 'riceboys' with their lowered Acuras with coffee-can exhaust, they love the blue lights, so the test was done to see if they really put out "85watts through a 55watt bulb" as they claim. Nope. ----- Original Message ----- From: "Mark Bergman" <[EMAIL PROTECTED]> > emit light that's somewhat similar in color temperature to that of an HID lamp, > but has a very different intensity and spectrum.
