I'm looking forward and contemplating lighting for my new 240g (96x24x24).

My initial plan was for two 48" 2X250W+T5s Outer Orbit fixtures, especially since I already have one fixture. My ideal plan is five Hamilton Cayman Sun 400W HQI Systems with LED lights and Hamilton 400W HQI ballasts.

I'm not concerned about the electric bill, but I am concerned about the amps needs to run all these 400Ws.

On average, how many amps is required for a single 400W bulb/ballast? I guess I can contact Hamilton Technology, but I thought I'd throw it out there.

I know I have 20 amp circuits and the room has four available outlets, but I haven't checked to see if the outlets are on one or more circuits. I'll play with the breaker switches this weekend and find out.
