Ok, I wanted to do a Solitaire mod, but it seemed to me that doing it the easy way (just removing the lamp and glueing the power led to the alu body and the black plastic part) would not be good for heat dissipation, so I decided to make a small heatsink.
I took a screw, cut it, bore a small hole and ran a wire through it, soldered that wire and a spring to a contact, and glued the contact to the screw. On top of it I glued the xp-g r5 emitter.
Next I bored out the mag and made an appropriate winding for the screw
The last thing I did was fitting a slightly too large DX clicky switch in the tube (used the winding of the original tailcap and sawed the rest off, then made it fit to the switch) by just filing it a little.
HOWEVER, I didn't put a resistor in there! The worst thing is, I didn't forget it, I just didn't want to put one in!
ADVISE: To be on the safe side, always limit current, or the light can go! What I did is a little risky, but at least I used protected 10440's (Trustfire grey "600mAh"). Ok, the protection circuit is not the best, but it jumps in when I try to short the batt. The actual capacity of these cells is below 300mAh by the way.
I put everything together and this is what came out :
(optics: white Ledil)
On very fresh cells I actually measured 1.5Amps+! How is that possible? That's 5C on the cells! And my multimeter isn't faulty. Must be the low Vf of the xp-g?
The protection circuit didn't jump in... definitely not healthy for the batt!
I am only running the light for 20sec max! Otherwise it would get too hot. No angry blue light until now.
1.5Amps would mean 460 lumen!!!! Can't judge if this is true, it is definitely VERY BRIGHT though!
