NO = normal output
PC = power compact
VHO = very high output
MH = metal halide
You'll need about 330-440 watts of VHO lights, more is better, and MH would be the best.
When I looked up some Metal Halides--I saw they were the screw in kinds--are there Metal Halide lights that I can buy that's compatible with a 2-pin? Or if not, can anybody tell me how I can customize my Eclipse tank to fit the screwable kind? Thanks!
You can't just replace the bulb. The whole setup will get messed up and fried if you do. You'll need to get a whole new ballast, socket, and bulb. And the MH bulbs will probably melt your canopy on the eclipse tank.
