Lots of people have silverstars burn out on them like you said. I really liked my sylvania cool blues, they were almost as white as the silverstar. I’m going to use the new silverstar next year, something like siverstar extreme or some crap…suppose to be much longer beam . piaa’s are nice, longer life than silverstars, but lots more money. just buy silverstars from wal-mart and when they burn out just exchange them.
