Is it that the lights cause alge if they are cheaper? or just not enough light to keep anything alive?
Right now i have a 48" marineland and a 48" reefbright running now and they seem to be doing thier job.....? i would need atleast 6 fixtures to flood it with light but that are still very reasonably priced. Im still learning with the LEDs and thats what I want over my tank but not in the 2k range anytime soon so Im looking into this as well

People generally don't like the 1W fixtures because there's better out there. LED's are weird though, if you put a tight lens on a 1W you could get decent par, just terrible spread. Same with the 3W's, they might not use R5 binned LED's, but you could get decent results in theory with enough lights.
