Re: Hydrofarm 125w CFL fixture [Re: alienscience]

I know this thread is old, but just for the record, when you use electricity in any form it generates heat, and since HID lights are more efficient they technically generate less heat, its just that they are such high wattage they get way hotter. But each amount of wattage creates a proportional amount of BTU's...


"Almost 90 % of electrical energy provided to an incandescent light bulb goes as heat and rest as light.

A 100 Watt bulb puts out 100 Joules of heat per second. So - for one minute it would put out 6000 Joules (100 Watts X 60 seconds).

1 BTU (British Thermal Unit) of heat = 1055.056 Joules.

So a 100 watt bulb, burning for one minute would put out 5.68 BTUs of heat. ( 6000 Joules / 1055.056 Joules) = 5.68 BTUs.

Same bulb burning for one hour would generate 341 BTUs of heat.

Since incandescents are super inefficient its not the same for CFLs and HIDs but CFLs are less efficient than HIDs which means they make slightly more heat per watt!
