New-117 (TK35 clone) mod. Turn a TK35 into a TK35UE (Updated with Beamshots 3-jan-2015)

Oh and this thread “17mm single-sided / DD driver w/ low parasitic drain for e-switch lights: AxxDD-SO8+LDO” started by a very smart guy at 17mm++ single-sided / DD driver w/ low parasitic drain for e-switch lights: AxxDD-SO8+LDO seems to make a good case for a design with no zener diode in it, although this TK35 clone is clearly a clicky light (aka mechanical switch) and as the thread says thus parasitic drag is a non issue, but the moonlight mode argument is a good point.

I wouldn’t bother for this application. If you are interested in very low moonlight levels then one of the new drivers (DD+single-7135) would be a good choice except for the lack of a Zener or LDO. You can still Zener mod them as I mention briefly in this thread: [WIP] 17mm DD+single-7135 driver / single sided / Dual-PWM
