LOL- You should see how bright 12 of them are @ 1400ma each. It's like staring directly at the noon day sun.

I've got 12 Vero 18's on a 6' Makers Heat Sink and cooling fans are a necessity. Don't skimp here. Keep the Vero's as cool as possible.

That driver's not going to work. It's output is only rated for 12V, so it won't light the Vero 18's. I recommend that you use the newer Meanwell LDD-1000H and a cheap 36V DC power supply to power...

Your initial led count is to low to reach "high" light. I think you'd be better off aiming for "high" light and then dimming them to reach the "medium" level. For a tank that large- take a look at...

Looks nice! I'm still running a 50/50 mix of the 2700K & 5600K Vero 18's on my tank, but I'm considering swapping out some of the 2700K for the 5600K versions.
