I have 48 Lumileds PWF6-type LEDs mounted to metal pucks that I would like to make into a fixture for my new 55gal salt-water reef aquarium.
I'd like to power the LEDs at 300-350mA each, which would make each LED voltage around 3.2V. This provides about 72 lumens / each.
Theyre mostly neutral-white LEDs (just blue dies with green phosphor) and a few cool-white. I plan to scrape off the green phosphor on some of them to make em pure-blue for the live corals.
Question is, which driver / power supply combo would be best to plug into a typical 120V household socket?
I also hope to add potentiometers to dim each string of series.
I did some searching and found a couple aquarium builds, but they all seem to use tiny 10V power adapters with higher voltage output drivers (like 24-48V DC output). Like this: http://www.nano-reef.com/forums/index.php?showtopic=261164
I'm worried that it might be too small of a power supply. That seems kind of expensive, too. So, please share if you have any ideas that are cheaper.
