Given the technology that's available it was only a matter of time.
Hmmmm... how easy and cheap do you think it would be to get a couple of hundred white and blue LEDs wired-up to a couple of power supplies and timers?
I see people on Ebay selling do-it-yourself moonlight LED
kits for dirt cheap so obviously the parts aren't that big an investment...
While not as sophisticated as their fully dimmable computer controlled setup, I think you could easily make a basic 3-cord, 3-timer LED
hood if you could find the right wavelength LEDs.
Maybe something like a layout of 200 daylight LEDs on one circuit, 200 actinic blue LEDs on a second circuit, and 20 "blue moon" LEDs on a third circuit, each with their own on/off timers?
I might have to start a new pet-project soon...
