Has anyone tried putting together a fixture using a light like this? Running the numbers through Hoppy's calculator I end up with a low light at 2 strips, medium light at 3 strips, and high light at 4 strips. Would be a pretty simple setup and wiring.
And has anyone tried setting up a system with colour-changing LEDs? Like the ones with a blue, green, and red diode installed on a single chip? Seems to me like you would be able to 'dial in' the exact spectrum you want, and with a bit of programming could have your lighting change through the day to simulate a period of light. Lots of blue early in the morning, simulate a sunrise, to full intensity in the afternoon and fading out in the evening back to blue. I've seen reef guys get pretty advanced with this programming, could be cool on a planted tank as well.
Rapidleds.com get yourself some 3v cool whites of 10000 3v royal blues of 460 or 450 red at 620 660 is good as well ratio 2 whites per blue is what I used for a 55g. Running great and plants are thriving I have 12 chips all together
