"I also still cannot find a single place offering these ballasts for sale and naming a price. All I can find are PRs announcing distribution agreements."

Hey Naysayers - Do a Google Search for 'daylight harvesting ballast' and many of your questions will be answered! There is lots of info on DH Ballasts available.

. . . and, my take on "whut's the price?" If you are a legitimate contractor and are sincerely in the market for buying/selling and installing these units I'm sure you can find a price upon contacting your local lighting distributor. I'm betting too that "tire-kickers need not apply..."...

Booyah!!!

OK....; found on the Web -

"The costs really depend upon what system is selected. The aforementioned system for example, carries about a $125/ballast cost, plus some additional wiring and control devices. So in a typical 30 x 40 kindergarten class with 16-2' x 4' fluorescents, you can see that you are looking at 32 ballasts, (unless you tandem wire the fixtures). 32 x $125 = $4000.00+. That would be a tough payback period to sell. Unless you are going for some kind of LEEDS certification, the District would really need to be "Green-minded"."
