An E1e was modified using an E-can, 6 ea. 5 mm RGB flashing LED's and a MadMax
voltage regulator:
An aluminium slug was turned and milled to serve as host to the LED's. The LED leads
were potted with Arctic Alumina prior to final assembly. The "AA" served to secure the
LED's as well as provide some thermal relief via the Al slug and into the head of the light.
The integral reflector was bored and them milled to provide scalloped chambers for the
LED's. The MadMax was adjusted to provide 3.5 volts output to the LED's on a fresh 123
cell. At this voltage, the raw current draw on the battery was typically about 330 mA. This
assembly would have worked with standard 5 mm LED's as well.
The colors and combinations of mix are very difficult to capture.
