To avoid my ceiling temp from going too high I allow the tank to cool down by morning to 78. It still hits 82 before the halides turn off. It takes until early morning when I get up for it to cool back down to 78. A big swing compared to most but I refuse to run a chiller anymore.
Brad's sick of the LED electrical savings already! Buying a heater now?
Do you recall what your system's total draw was over 24 hrs before with halides? I'd be curious what it will be with a few hundred watts of heating and the LEDs.
