500 w halogen grow light for watts, and a cfl tube or 2 for spectrum?


New Member
Okay, so someone i know wants to start growing, and they have this new 500w halogen grow light, and some cfl tubes.
My question is if you put the grow light a few feet above some plants, and cfl tubes around them for the spectrum would this work or help?
I know something about cfls being about 1/4th of the watts from regular bulbs, so in this case wouldnt the light be the equivalent to a 125 watt cfl?
Any helps appreciated. :thanks:
