What to do with discarded LEDs..Use them as desk lamps! Duh! A while ago I recieved these 12″ strip PCBs with 30 high intensity LEDs on each. I took 4 and attached them to a board to see how much light they would emit together. Turns out that they put off what appears to be about the same as a typical 18 inch fluorescent under cabinet fixture. I now have two that illuminate my computer desk.
