I think the people that complain about melting lenses are the ones that use 55w instead of 35w (from what I read). I have the 6000K in my headlights 8000K in my fogs both 35w sets and so far I have had nothing but good luck.

YES my fogs are much brighter then they were originally, they need to be adjusted, but they are brighter. The 4300K's you ordered will actually be brighter then mine. Well maybe not brighter, but more "true" light. Mine have the blue tint to them.
