if you want pure light and longevity go with the silverstars, but there is another company... ummm SRAM or something like that, that makes the european silverstars. And the european silverstars dont have the blue filter film over them which is probably more of what you want. So do a search on ebay, but find out the real name of the company first.. I'm, not 100% sure thats the name of the company.. but anyway, they should cost the same considering its essentially the same bulb..
