Another LED question

[monocus]

i think the epistar leds are at the bottom of the list of leds-you don't say how big your tank is or how deep-which will affect your par.i didn't see any lenses on the unit but a 120 degree will cause a lot of light pollution.myself i stick to 60 degree.one light would do for a 28"x16" tank.the price isn't bad and at least it's dimmable
