BTW, I did some research(wow, I never do that) and found out that purple LEDs are good for the job of plant lighting... so are green LEDs(I think)
Building My LED Light
- Thread starter traelman
- Start date
This guy, Wayne Schmidt, has done a good bit of research on plant lghting, and has presented it very well.
It tends to agree with what I've found, which is plants like bulbs that are strong in the blue and red portion of the color spectrum. Looking at the data sheet for the Rebel LEDs that I'm using they perform well in both of those spectrums.
Now that I have the LEDs working I can start on the enclosure to house everything. So its off to LOWES.:headbang2::headbang2::headbang2:

As promised here are some pictures. I have three lights hooked up, running at 3.4V/1000mA. Thats about the max they will handle. they look pretty good. I'll get some pics in low light tonight. These were taken in front of a sunny window and they are still really bright.

and now 1oooop comes along to enlighten everybody... there are actually these electrical devices that move heat
and you can actually make an air conditioner out of them, only problem is the wattage they use up... here's a pic
and how it really looks like
meh... peltier modules...
My wife said she has burned retinas.:lol2::lol2:
Anyway these things are pretty cool.
As far as the heat issue, I turned the fan for the power supply towards the heatsink and it seems to be doing a good job of keeping things a little cooler, by at least 10 degrees.
These pics are of all six LEDs, wired in parellel, being driven at 500 mA. This is in the middle of there operating range, so it should actually extend their life usage.
The last photos are of my existing light and the new LED array.
I'm really glad that things are "looking brighter"!!!!:headbang2::headbang2:

peltier cooling methods are pretty inefficient for cooling anything that puts out too much heat.... They also produce condensation. -Not a big deal for a fish tank, but a big deal if near electronics... like LEDs.
