That's great to hear as I don't want to have to manually adjust 8+ of these
I've spent some time reading through this thread since my interests have peaked on multi-chip LEDs.

I'd have to agree with you that multi-chip LEDs are the future for sure. When I was considering the 3 Watt LED DIYs for a tank my size, I could not even fathom the amount of soldering that would have to take place....But with using 20, 50, and 100 watt multi-chip LEDs that becomes much easier to achieve and a little thermal adhesive to heatsinks designed for CPUs/GPUs.
