i am also having a hard time getting past how much some of these sites are charging for a diy kit(most of them not even including the heatsink). wondering if i would be better off buying something like these and getting more light and paying less then a lot of the diy kits i have seen.

i also am wondering if there has been a standard set as to how many watts per foot you need. I have read quite a few threads and the number of leds used varies quite a bit and also have noticed that most people down even end up getting their fixtures up to 100% intensity once they are acclimated. so, do i really need 200-300 watts of leds over a 4foot 120 mixed reef with a bit of sps near the top??
