It just came and is even smaller than I imagined. It's very nice looking, but I will likely either paint the gray end caps black or machine new ones from aluminum and send them along the next time I have to get something black anodized.
The legs do slide out to adjust, but not a huge amount. The fixture itself is 23 5/8" long and the legs look like they could extend out to maybe a max tank width of 26". This doesn't matter to me as I'm just setting it on my glass top.
The light color seems great...I'm not perceiving any yellow (I got the 7K/7K version). The light spread for each LED is also very impressive. I put my hand directly against the splash guard to block the light from numerous LEDs and expected it would create a giant shadow on the floor....nope. There was a vague dimming affect on one side, but I had to look for it.
Sorry for turning your thread into an improptu review...I'll try to post some pics in a few days.
