Got really high, really bored, and decided to get really burned making this panel.

Cut a bad panel in half, stripped off all of the diodes and bypass diodes, bypassed the cut traces, and at first started just soldering all red (left side of the panel) but then tried to just start tossing them on at random grab from the bin.

Aw thats alot of anode cathode soldering bro.............solder temp 365c ?/.............nice work.............the drivers dont realy care how many diodes it runs up to a set max voltage,........how many 3w to the standard driver 42 diodes yea ?/...............AB.........................x3 ?/..................

Ps; how quiet are the new fans less than the 38db of the olsd one tea, half that say 15db's ??.........normal conversations is 28-32bd's............so half that bro?/........AB...

say Yep, a lot of hand soldering since no solder paste for reflow. Iron temp 315C, low-temp RoHS solder. Ahhh, 50 diodes on that panel. (was a 100 LED panel cut in half) And while using 3W LED I'm only pushing like 525mA so at best 1.5w per LED.

Could probably use this to grow small plants or a single medium sized one if I wanted. Throw inside of a large PC case with a hole cut in the top for the heat sink and fan, would take up almost zero space.

The fan I'm running for just this is 12VDC @ 0.3A and isn't much louder than any other PC fan. It's one salvaged from an old 90w UFO from the old days when 'real' LEDs were still attached to green PCB instead of metal, powered by a 12V wall wart that went to a rechargeable radio set. It's pretty quiet. You wouldn't hear it in a closet or over your own computer, most likely. I will give a rough ear estimate of about 25db or so. If I pumped it to 1A forced I bet you it would sound like a jet engine!
