okay i didnt know that lol i just thought the little box thts hooked up to the bulb is like a ballast or something. well i was comparing brightness to my friends sc400 we put a led 6000k kit in from OPT7 and it was super bright and had length of brightness. i myself didnt get a kit like his i just got led bulbs only so i was curious if the box wired to the bulb and integrated chip and fan on the bulb have something to do with better light out put? thanks
