If it isn't a flourescent, HPS, or MH, then from what I know, it won't work. Check to see if its actually a CFL (compact flourescent light) and the 50, 60, & 65 watts is actually the stated watt usage. CFL's have low watt usage but put out a lot more light. My 42W bulbs each put out 150W (2600 Lumens) and I have 2 of those over my babies right now. Goodluck.
