I call it the "El Cheapo Thrower"...
It was an eB*y LED torch that runs on 3xAAA.
(My first "High-power led" flashlight, bought in 2005...)
Done it in december, but did not find time to post until now...
Mods done:
a) Emitter replaced;
b) battery-config changed from 3xAAA to 1x 18650;
c) Switch-housing modified to fit 18650.
Showing threaded heatsink with XR-E epoxied...
I used some 3M tape to isolate the reflector, so it will not short the led...
Some views of the parts...
18650 cell needs some foam so it will not rattle in the tube.
Head assembled. Switch ready to drop into tail.
Battery inserted, wrapped in foam.
Assembled...
This animation shows what the eye sees.
And what you see is the throw this little thing produces on a
building at approx. 100yrds from where I stand...
You can even see the corona shining on the building at half the distance...
Quite impressive what a few mm's of phosphor can do, eh !
Cheers !
