Hi, I would like some design suggestions, ideas and links for my new proposed rebel-tri-star array for coral reef aquarium application. (office tank).
I was going to use some of the blank rebel - tri-stars they sell here.
I was thinking of the following on each star to accomplish 20,000K lighting, I would setup a 25 star array consisting of 75 LEDs for starters.
- 1 cool white 145 lumen on each tristar
-1 royal blue 440nm on each tristar
-one blue 470nm rebel on each tristar
I would run them off two PC power supplies connected in series to provide 24VDC.
I would power each strand of 6 LEDs (3.15V Vf each) with LM350's (3V loss) w/ a resistor between Vout and Iadjust to set the current at 800mA each.
It would also put a endor tri lens to increase output and direct the light to the tank.
This is basically a DIY version of the newest solaris but using my own blend of lights and bins. I think this version could easily surpass a 400W Metal halide, but cost is huge. a square foot of lighting will likely be $500 or so in parts.
*My biggest issue is heat dissipation. I would have to mount the rebel starts on a RAM heat sink and actively cool it.
*Mounting heat sinks w/o screw holes is also a concern.
Do you have any good links/suggestions or have seen anything that I could emulate for my new project?
(I've built several aquarium LED arrays in the last 5 years, I'm at revision 4, Just google ' zachtos LED ' and I should pop up right on top.)
