Hey I just bought two 18w compact fluorescent bulbs. They're not the screw on socket bulbs, they have four pins about one centimeter long and one centimeter apart from each other. They're all in a row. There's a thing in the GrowFAQ that shows how to modify compact fluorescent bulbs with the screw socket and have them running in parallel with each other through the same wire. Can I do this with the bulbs I got? They scientific term for the socket is "PPL 18/65." The socket for these are expensive an I don't want to pay that extra cash for them.
