No trouble at all Brent, there wasn't much more to show. All I was able to do was get a couple of them fired up at your place, one blue & one white. It was a busy venue!

For what it's worth, I made a few photos of the set up over my tank this afternoon/evening. I'll try to get several more tomorrow with the T5HO & Halides for comparison, but just looking at the photos compared to real life, I must admit the photos don't really tell the story. Seeing the LEDs over the tank has given me more incentive to finish up the build & replace the old lights. Anyhow, here they are:

All LEDs running with the fixture 7 inches above water surface. Blues & Royal Blues set at 8 VDC, Cool White & 10000K White set at 9 VDC. So in effect they are all being driven at somewhat below their maximum forward voltage. Still very bright & the colours are blending nicely. Did not perceive any disco ball effect.



This one is only the 5 Blues on the center rail dialed down low, set at only a few volts with the heatsink fans barely turning.
