how do you do that?
Right from the Diamond web site under lighting.... 9' - 59 watt - single pin - F096/741/ECO
I bought mine from the local ACE Hardware. Not sure why some guys are saying they are impossible to find. ACE had plenty of them.
FYI, not looking forward to the day one of them burns out. The diffuser is a pain to get in/out. It's a very snug fit.
