My old ballast was a dual 250W HQI M80 type ballast that was a full 9 amps + two 54W T5's = 608 watts of pure heat. The new Powermodule is 5 amps with 540 watts, the heat must be at least 50% less.
My tank now stays a full 2 degrees cooler than before and my heater in on more often. The room itself is way cooler and the cooling fan almost never comes on. Not to mention the chiller will almost never come on now unless it is 35 degrees outside.
I am not sure what the power savings will be but I am sure I will see some. I am actually not too worried about the savings, I am just so happy about the way the tanks looks and the fact it does not bake the room.
