I've been reading through all the LED threads on RC(several of which have gone into the hundreds of pages in length), and from the data I've seen(cant view stuff hosted on pb from work, I can get the graphs later), the best LED are the Cree XP/XR series, which Rapid LED sells in their kits - most have recommended 48 LEDs minimum for tanks ranging from 75-90 gallon tanks - especially with Optics(both 40 and 60 degree)- I have a 65, and plan on dialing back a bit on power(its easier on the dimmable drivers AND the LEDs to not run at full power) - White LEDs will have 40 degree, and Royal Blue will have 60 degree optics.cjdevito":13d7w20j said:budhaboy":13d7w20j said:gonna go with a DIY kit from Rapid LED(48 led set - 24 RB, 24 CW, equal to 2x250 watt MH)
Just a cautionary question here... equal to 2x250w MH in what way? PAR? Lumens? Something else?
There are a lot of equivalency claims out there where LEDs are concerned, and a lot of them seem to be hype more than substance. Don't get me wrong, I use LEDs, I love LEDs, I just want to be sure the kit you're looking at is really going to give you the performance you're expecting from it.
