The MS lights can be customized for you, and they are decent people to work with. I didn't get a chance to see Darin's setup, but he seemed to know what he was talking about, so probably ok. Don't know about a warranty with Darin, but you do get a warranty with the MS LED's. If you want to go with something that is off the shelf, proven, analog dimmable, and configurable optically, you can also go with AI Sol's or AI Sol Super Blues. I'd go with the AI Sol Super Blues with 70 deg optics, and a mix of CW, Cyan, and Royal Blue on each 3-chip module if it has to be a well known national brand. You can change the optics yourself if you don't like the results.
