My setup has 3 rows of whites, 3 rows of blues, and a row of reds in the middle. I bought my tank used and it came with a (mogul) metal halide fixture, but with the tank being in my mantown in the basement the metal halide was out of the question. The tank alone makes the room hot, let alone putting a metal halide light and then most likely a chiller. So LED was the only option for me.
I got my Auraled lights yesterday and they make the lights on my other tanks look like garbage. These lights are incredibly bright. And unlike most of the LED setups I have seen that shine straight down these ones light up my whole tank(ZERO DARK SPOTS.) As far as par readings go, my lfs doesnt have a meter I can use and I am currently trying to scrape up $300 for the "Apogee mq 200." Hopefully I can get one soon.
