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...

18650 cell needs some foam so it will not rattle in the tube.

Head assembled. Switch ready to drop into tail.

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 !

Welcome to CPF !!

The wires are soldered to the emitter on the top-contacts of the Led.
Because the refector is metal an screws down onto the contacts, you need to
isolate the bottom of the reflector. Many use Kapton tape, but I had none
ate home during the mod. I cut a piece of rubbery 3M sticker to fot the bottom
of the reflector...

Cheers !
