for depth, yes, but not full coverage. I think to get it even, you'll need 2 front and back each 2 feet of length. With single sols over my "growth area", I still don't have enough back to front to cover the 18 or so inches. Trying to save can be disappointing when you plug the lights in and see that it's not enough. But he can try 3, if not enough, just order the fourth...
