Do you have the PIAA SuperWhite of the XtremeWhite? The SuperWhite is 3800K, the Xtreme is 4000K, just like the Silverstar. If you have the SuperWhite then you will see a difference going to the Silverstar. I've had the Silverstars, the PIAA SUperWhites, and the PIAA XtremeWhite in my truck (I have clear lamps just like yours but square) and couldn't tell any difference in the whiteness of the light between the PIAA Xtreme and the Silverstar, but both were noticeably more white than the SuperWhite. THe only difference I could tell was that looking at the light itself, the Silverstar has a purple tint and the PIAA XtremeWhite has a blue tint, which makes sense since the Silverstar has a purple coating and the PIAA has a blue coating. ANyway, the actual output appeared the same to me and as far as I can tell the output on that Element is like what I got from the Silverstars and am getting from the PIAA's.
BTW, you should be ashamed of yourself for viewing the Element board!
