Josh did you get the dimmer controlled unit. Plus im gonna start another 10g would one be too much for it
My frag tank is 11gal. Cheapest 1w units. It has 104 leds. 52 white and 52 blue. I measured the par (don't know how par measures on leds) with both lights on par is 200. Just white 80 par and just blue 120 par. I will send you a pic later so you see the height. Dimmer units are a lot more expensive and a lot of this units you can dim with an $8 home depot dimmer.
