Fluorescent Lights - ballasts


New member
Was replacing a ballast, and came across the thread here, http://www.reefcentral.com/forums/showthread.php?t=1403281

Well, everything is about as described, but one of the lights went out, so either it is a bad socket, or I did something wrong. Now, I only have sockets with two holes, so I have blue and red each on a lamp, then I split off yellow so that there are two yellows in each of the other lamps. Since the one side does not work regardless of bulb, I'm thinking a socket is shot.

Is that even possible? Should I just replace the two-hole sockets with four-hole ones...? I see they are cheap at least.
