Inspiring by wayne's XM2, I got my self to make this inexpensive, easy mod, not regulate.
http://www.acad.polyu.edu.hk/~02938190d/policelux3/
I simply just add a 1ohm 2W resistor & a 1A 102degrees C fuse (to avoid too much over-heating). I not sure the heat can be dissipate as fast. Fortunlately, the fuse is not blow when with fresh 2x123A as the current is something 1.2-1.3A in my meter.Sorry i havent done the runtime test of it. But it will be expected to have more than 1 hr high output.
There were several kinds 2x123A Police flashlight that selling. This one is the shortest type in length(4.5"). So, I found diffculty to make a thicker heatsink instead of the original one. Not enough space... Wayne must do far more better in heat problem of his XM2 i think.
In fact, i dont like an unregulated much. However, i found this is my cheapest option to have a high powered lux3.($20+) /ubbthreads/images/graemlins/grin.gif it's the way to go
