Think about LED as being similar to T5 in that you need to pretty much cover the area that you want to grow; light doesn't travel very far off the side of the fixture. Having said that, I bet that you would need multiple of those 100 watt units to cover your grow area. If you want to do that, then LED can grow some fantastic bud (really trich laden) but if you don't have the money/ inclination, T5 can grow some excellent bud too. I probably wouldn't go with a UFO anyway. There are better units and quality counts a lot with LED lighting.
