I agree, Bill's are very nice. I like mine. Reefledlights.com
210 AGA. I've had them on since the JARC swap.
Overkill for my 29 gallon. It's actually one of the ones I've got on my 210.
The advantages for me really is the heat they don't produce, and the fact my electric is way down. And that they grow sps in the gravel of a 29" deep tank.
You are correct. I like the extra blues alot. Makes for a 14K look with everything on.
Reef Bright LED's all day long, look at kraylen's prop tank only one 50/50 and everything is doing great. I used 5 and love them, I even had to turn them down with the dimmer.
I would not do LEDs over such a big tank for these two reasons.
1. There are no LED fixtures on the market that I know of that can cover a 34" front to back spread.
2. Once you get to larger tanks IMO efficiency drops. You will need many more LEDs to cover the spread and intensity that a single MH (with a nice big reflector) can cover. Something like a luminarc III can do a 36x36" area. You could probably get away with 2 x 250w MHs on your tank.
Anyone who is against LEDs usually has not had their hands on many... or were touching the wrong ones. I got 1 RB/30w covereing a 48x15x15 no problem.
