This is the model I have. E-200W-3G-2:1
Bought from my LFS, first one a couple of weeks ago. I went yesterday to get some supplies, and they had all their LEDs on sale, great price couldn't turn down.
I tried a little experiment with my coralife fixtures. They are 36", each has one
39w 10.000K one 39w actinic. My tank is built into the wall. I moved the LEDs back a little almost even with back of the tank. I put the fluorescence back on and pushed them against the wall. So they are about 5" from the front of the tank. I like the color a better, I am going to replace the 10.000Ks with actinic's and see how that looks
