If I had a dinosaur to ride to work, I wouldn't be riding to work!! lol
Best light for SPS growth, Iwasaki 65k MH on HPS ballast. Best color, 400w Radiums. Best of all worlds, some sort of LED. Money being no object, I would go Vertex. If money doesn't grow on a tree in your back yard, AI. Sure, Radions are nice, and with adjusted price, maybe a better buy, but at the old double AI price, not worth it.
Kessils are nice, but comparable in price and coverage to AI Sol. AI Sol plugs into Apex controllers nicely, a good feature.
Not into LED, but MH too hot? Can't lose with all the available T5 bulbs out there. Some of the nicest tanks I've seen are lit with T5. The rest are lit with Radiums
A local guy is setting up a 12 foot tank with plasma, I'd like to see that once it's all done.
