You have 100 of these fixtures? How many tanks do you have? Are you a LFS?
The unit appears to be physically very similar to the early gen 1 Sunbrites, which used a plastic case and the mega-quanitiy of LED approach. However, Sunbrite used higher end, true color LEDs (Edisons I believe) and were all a sole spectrum in a given tube: options were 10k, 12k, 16k, 22k, 470nm, or 440 nm. I still use a pair of late Gen 1 bulbs in my system (same approach but metal case and improved power supplies in the ballasts).
Your bulbs used a 50/50 mix of 440 nm with a yelow spectrum 5.5k LED. Keep your eye on algae growth with that 5.5k spectrum.
On my 135g (18" across) with early Gen 1 bulbs, I needed 6 to 8 tubes across the tank to keep acros happy long term. However, YMMV! :-)
Detroit's oldest large LED tank! Est'd Jan 2005, went LED June 2009. 6' wide 130g reef, Sunbrite T10 LED tubes (3xGen 3 and 1xGen 1), mostly SPS, but chalices, other LPS, and a few softies too. http://pjr-reef.blogspot.com/
