honestly depending on the size of tank they really only recommend one about every two feet of tank space. I am not sure on the PAR for it, but I'd be curios. Honestly, I get totally lost on all the light info. All I know is it is working awesome in my tank and everything has good color.
TAT-2Z, I am wanting to retrofit my 14gal biocube to LED and thinking of doing it myself. Any suggestions? I was looking at some kits on line and it looks simple enough. I figure if I could change out valve cover gaskets, spark plugs, and normal vehicle maintenance I should be able to follow some directions for lighting...I hope lol. But, would like some suggestions from someone who has built their own.
