Here is a thread on LEC. I have my eyes on one just don't have the $ right now.

I have 2 LEC315 in my 5x5 and I can say it is not quite enough light. My temps stay like 63f with lights on so I can say its gonna be easy for me to throw like a 600w HPS in there for the next run; which is what i'd suggest.

2x LEC315 with a 600w HPS imo would be prime as hell in a 5x5. Chopping this tent in like 2-3 weeks then i'll be throwing another light in.

That being said i have 4 huge plants taking up literally the entire 5x5, if your plants are a bit smaller and dont entirely fill your entire 5x5 you might be able to get away with it

I love the lights I honestly do, I just think you need a little more juice for a 5x5

2 315s should be plenty of light in a 4x4, it's the equivalent of at least 900w due to their high efficiency. Just make sure your canopy is receiving 5-6000 foot candles. I'm running one fixture with a 210w bulb and one w/ a 315 in a 4x4.

these 315w LEC systems are serious business. i've got one over a 40"x40" space and the nodes are tight as hell in veg, but i haven't gotten to flower a run under it yet. @GroErr runs them for flowering, he might be able to give you some good advice on square footage.
