Re: [APD] LED Lighting
There's nothing to stop one from using the new super bright
LEDs for lighting a tank. There are a varitety of color
temps to satisfy diff tastes. The problem has been the cost
of the LEDs and the assembling a suitable array of the
devices to light a tank.
It's not impossible to make such an array, just a pita. And
if one doesn't get the voltage right, the LEDs burn out
Try running them at a bit below the rated level. If you use
diff colors (red, blue, green), then put the diff colors on
different circuits back to the power supply -- the reason
is that diff colors heat up and draw current at diff rates
and the LEDs will tend to last longer if you yu keep them
