I found these 24" LED fixtures (108 individual LEDs) in 460nm blue

This company is in the City of Industry and makes all sorts of LED products. I got mine shipped to SD very quickly but I think they have walk in hours as well.
I placed 2 of them in the canopy, one on either side in the far corners and angled slightly toward the tank. I can see the color difference clear as day in person, but some others have not noticed as much difference. They are much brighter than moonlights. I'm very happy with the result so far, my tank is 30x30x24 and these have no problem covering the whole tank, though they might be brighter if they were a more focused beam (these are 120 degree view angle.....big spread). I imagine on a smaller tank or standard long tank one fixture of the proper length would suffice for actinic supplementation. Some may think this is still expensive (2 ft are $70 each) but I would have had to buy 6 Powerbrites for the same coverage I believe which would almost double the cost. The pics are all taken with the same camera settings and pulled right off the memory card (sorry for the quality, I was only concerned with light color). Here are the results.
2 24" Blue LED fixtures only
2 24" T5 super actinics only
mix of the actinics and blue LEDs
