Here's what I observed. I was out and about last night driving some local sparsely used unlit roads, so I was able to make good observations with the PIAAs. First and foremost Eckoman is correct that they light at about a 5000K color temp rating. Very differant from the SilverStars I had in. The light output from the Super Plasma GT-X bulbs is the closest to HID I have seen yet in terms of color and look appearance. I'd compare them with Acura TL HIDs running at about half the brightness. But the color is almost exactly the same. I was stopped next to one so that's how I conducted that comparison. With the high beams on they transform into a more white output level of color. They seem to have a blueish/green tint at the edge of the light pattern that I'm not terribly fond of. Still very bright, but definitely NOT any brighter than ther SilverStars. The Silverstars are as bright if not brighter than the PIAAs when in highbeam operation. This could be due to the color temp differance, but maybe not. When the S/S's are in highbeam operation, rather then the light going whiter, they seem to tint slightly BLUER which is opposite of what almost every other bulb does. But I almost liked them better because of that.

As for lowbeam operation each bulb between the S/S's and the Plasma GT-X's they are about equal as far as lumens brightness output. Actually the PIAAs I'd almost go with saying are slightly brighter. Because of the color of the light been emitted from them, they seem to reflect the light back up better off the ground as well as off of road line marks and cateyes, better. When I bought the bulbs, the shop told me I should match a yellow city light bulb with them in my city light sockets to enhance the affect of the GT-X's. I'm thinking of trying that out. rightnow I have Polarg M-4 wedge bulbs in my city light socketsfor my CTR headlights.
