SST-90 Emitter for DIY Aquarium Light?

[SC300TWINTURBO]

This might be off subject not pertaining to cpf, but I was curious to see how one person would make a DIY lighting fixture for a Aquarium using SST-90 Emitters. Whether it'll be one SST-90 or 3 or 6. How would one drive this? what type of heatsink should be use? and cool it off(fans) for at least 5-8 hours or constant run time.

Due to the high current requirements of the SST-90 it's more practical to use XP-Gs, XM-Ls, or Bridgelux for conventional lighting uses including aquariums.

A Cool-While Bridgelux C-1202 puts out 1,300 lumens at a stock 1amp, and costs around $11. 1amp ac/dc LED drivers are consequently cheap and easy to find.

A SST-90 needs to be driven at 6-9amps respectively to get relative value out of it compared to the emitters above, and good luck finding LED drivers in this range that also work at low voltage. This means you are almost forced to go with a DC/DC hybrid scenario to work off mains....unless you want to run them off batteries.

If you use SST-90, you need around 10A Driver and it will cost higher. or secondary 10A Low Voltage buck Driver with 20-30V SMPS.

but all above method expensive for that kind use.

best way is use few XP-G or Endor/Indus stars. these are rated for 1A. you can get 1A driver less than 10$ from ebay. these drivers capable of driving up to 10 LED series.

I think an SST-90 would be overkill, that's an insanely powerful and expensive LED, no?

Just a thought. Great inputs and advices.

Thanks
