One of my Super Plasma GT H4s went out, so I want to try the Xtreme Whites.
Does anyone know if there is a noticable difference in light output and color between the Xtreme White, Super Xtreme White, and Xtreme Force bulbs?
http://www.xtremewhite.com has them all, but their price are ridiculous compared to other sites like optauto.

Any help would be appreciated.
