Trouble with double lamp

norbizzle2012March 13, 2010

I bought a double t12 bulb lamp and i could only afford one bulb at the time so i was wondering if the lamp will completely work with 1 bulb. When i connected the single bulb in one socket it seemed very dim and when i connected it to the other socket it glowed orange at the ends. It needs a 20 watt bulb but im sure its supposed to be bright enough. Does it need the other bulb to work properly? plz help

Some light fixtures require all bulbs to be good and installed to work properly, evidently yours is one of them.

Each bulb is supposed to be 20W at 720 lumens is this enough for growing my seedlings. Also i bought GE Plant bulbs so i dont know if it is supposed to be less bright than normal?

IME, only while the seedlings are very, very small.
