Definitely let us know. I've never cared for the look of actinics only. It's a little too harsh for my taste. With the progress (and price drop) of LED's , I've been hoping something would come along that would allow me to view the tank in a more pleasing light (to me, anyway) in the evenings. This may be just the ticket. I had to remake a canopy for the tank. I've just about finished it up, but it wouldn't be too hard to still incorporate these into the lighting scheme.
If the saltwater environment is too hard on the strips being mounted unprotected, I'd think it wouldn't be too hard to mount the LED strip to a small strip of something (plastic, or even painted wood), and then mount that strip into something like the protective tubes they use for T12 bulbs.
