Hello all you fish freaks I am in need of a DE 70w metal halide bulb for just a few days until I can get one in. I called all the stores and none of them have this particular bulb in stock. I would appreciate your help as my tank has been in the dark for three days now since my first troubleshooting thought was the ballast. The ballast was replaced today and the bulb still lights up for about 30 seconds then goes out again. Let me know if anybody out there can lend me a hand/bulb just for a few days thanks.
