What to do with discarded LED PCBs? 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 flourescent undercabinet fixture. I now have two that illuminate my computer desk.
Step 1: Fabricate mounting board
Because these strips do not weigh much and also do not creat much heat at all I chose to secure them with cable ties. Also, I had these laying arround, so why not? I then took the scrap 3/4" thick board and measured to length and width and cut with a handsaw. I think the dimensions ended up being about 12" long by 6" wide. Lastly the mount holes for the cable ties had to be drilled. I drilled these a little narrower than the strips. One pair at each end.
