Hello,
I am an artist in Portland Oregon and I need to power an array of 3 watt cob leds (9-12vdc 260-280ma)
They need to be strung in strands of 8 (12 total strands) 96 total leds.
I would like to run them a little underpowered to reduce the heat and make things a bit safer and perhaps last longer? I've tested them on a small constant current power supply at about 2.5 watts strung in parallel and that seems about right.
How would you design the power for this, with safety and affordability being important. I am decent at following instructions...
Many thanks, Tor
