LED lighting · Prototype to finished build

Hamburger Ötzi

The LEDs worked; the prototype was simply too big. I rebuilt the three-LED light inside a Cateye HL-1500 housing, with a smaller copper heat-pipe cooler and a handlebar remote connection. The layered construction and the Ötzi cooler gave it its name: “Hamburger Ötzi.” The gallery includes the earlier prototype.
