This is awesome, thanks for the update. Do you notice any difference with the light on the sides since it is shorter than your tank's width?
I'm at work so I can't say, but I can provide you with a quote from Lowe from when I asked him if that was going to be a problem for me.
"Near the bottom should be fine if no tall plants are blocking useful light, however, even though the spread of the LEDs are at 120 degrees, Tall plants on the side may not be getting enough light. Just something to think about. Hope this helps!"
