BTU Calculator for COB LED's

Does anyone know how I might go about calculating theoretical BTU's of my DIY grow light? Is their a calculator somewhere?

My light has 4 x CXB3590 (3500k, 80cri) driven at 1750mA that are actively cooled on Arctic Alpine heatsinks and 2 x Vero 29 (3000k, 90cri) driven at 1400mA on passive 140mm heatsinks. The fixture draws 445 watts at the wall.

Is it as simple as figuring out how many watts are converted to light and how many watts are converted to heat based on the efficiency the COB's are driven at and then take the heat watts and convert them to BTU's? Or is it a lot more involved than that? I assume the latter.

@CobKits would this be something you could help me out on?

It's a lot less involved. All the watts are converted to heat, there's heat in that light. LED's just make more light with the same wattage.
1 watt = 3.415179 BTU/hour.

You should ask @CobKits . HE knows his stuff well. Actually has a thread going on right now too.

He might chime in..
