This is my try to replace the energy-hungry 150watt halogen floodlight I use for working on my lathe.
I think it went well..
Step 1: The Parts
The basic components and electronics are from DealExtreme.com
a PVC pipe, a pipe holder, a p4 heat sink and an old 24volt fan.
I suppose that connecting the led to the driver and mounting it on the heat sink with the optics is self explanatory so the photographs are enough.
