Re: [GSAS-Member] DIY LEDs

["Clifford Miller" <clifford@clevergeek.com>]

A year ago or so I got the full demo from someone with a 4-ft solaris
system (over $1200 worth of aquarium lighting at the time) over his 90
gallon reef tank, the equivalence of around 10 watts / gallon (and higher
par than standard lights).  It can be fully programmed and scheduled
(sunrise, steadily warming throughout the day to full daylight, then
slowly working back to just glistening blue moonlights in the
evening)...that runs virtually cool to the touch.  I have to say, it was
impressive.

If we have any DIY geeks, the best info I've seen is from the guys over at
nano-reef.com, specifically from evilc66...he's put up several days worth
of good LED reading (complete with metered PAR/LUX ratings for many of the
projects).

Great places to start are the "Ultimate Guide"
(http://www.nano-reef.com/forums/index.php?showtopic=186982), and
"Comprehensive Project List"
(http://www.nano-reef.com/forums/index.php?showtopic=200335).

You could use far fewer LED's for a standard freshwater tank than a reef
setup would need.

It would be fun to go from "do I have enough light for that species?" to
"will my lights burn this plant to a crisp if I don't shade adapt it?",
and save on the power bill at the same time...
