So as some of you may know, I run metal halide lighting on my larger display tank. The one concept I have issues understanding is how the lighting electricity use is calculated.
So my fixture is 2 150 watt HQI bulbs with 2 150w electronic ballasts. So am I running 600W of power or just 300W? I don’t have a killawatt meter or whatever to measure it.
