So I figure my lights at 300w right now. I have 4 cobs being driven @700ma from my wall @110v im assuming this is right, I went (W)=(V)(A) so (W)=(110)(.700) any LED guys out there to verify this?

Hi Brokeleg, your math is good (W)=(V)(A) but I'm not sure if ur cobs are 110v each. Is this a cumulative series wired voltage? In this case you should have 77W. For a detailed math I'd need cobs and driver model. Thx

No it's not like that. Just like your phone charger works at a reduced voltage (usually 5 volts) even though it's plugged at 110V, your lights works at a reduced voltage (how much depends on the one you are using)

Hi @Brokeleg! Indeed, that would make 308W but it depends on your resistance and the voltage drop. I recommend to get a smart-plug so you'll be able to track your energy consumption efficiently. Happy growing!
