So basically I'm on a mission to build my own LED grow panel as it is far to expensive to buy one. And this thread is not just about my mission but all others who also would like to have an affordable LED panel. Through the efforts of us as a collective, I hope this can be a thread that has the easiest DIY LED build eventually, and not a thread about how one person made an LED panel. I hope to have clear cut items and procedures to follow. For now we must learn: http://www.howstuffworks.com/led.htm http://www.kpsec.freeuk.com/components/led.htm http://unclean.org/howto/led_circuit.html http://www.kpsec.freeuk.com/symbol.htm My idea is to modify an LED Christmas light set and replace the bulbs with high quality LEDs at specific colors. I'm trying to figure out how to increase the wattage. Perhaps if I just cut the wire at the plug in, and wire it to this 12v dc 150w power supply. I will have small PC fans and housing for it all if it could work. Any ideas?
