If you're just looking for pop and not coral growth, then I would buy the AliE bars, as you can custom order the spectrum/diodes you want. XHO's are the most overpriced and cheaply made light bar out there. They have great pop, but you can get so much more from other bars for much less. The Quanta's aren't dimmable, but I treat them like T5's, so that's not an issue for me. I use three of them and I turn them on 5 minutes apart from each other.
Luca's (Quanta Lights) is currently working on a fixture (not a bar) that's due out in May. It's called The Helix. Give me a minute and I'll post some pics with just the Meso Blues on.
The XHO's use 470nm and 450nm diodes, so it's an easy thing to mimic/replace.
I think the Popular Grow bars can be modded with those two diodes for a fraction of the cost.
