Anyone? Don? Three beauties now waiting for an extender that doesn't sound quite right...

A Nichia 119 LE for Mule, Haiku, SunDrop XR-U or Makai head can certainly be made using the buck converter which would be appropriate for 2x123. Such a LE would certainly have longer run time than similar one powered off single 1x123. As for guestimating what batteries would provide how much run time, I defer to the guys here who are more up on the various batteries and their capacities....... Just want to know if Don is able to provide a 6V module with Nichia 119 to run on the 2x CR123 tube? Would it have better run time? .......
Ordered the 2xAA...

Personal preference I would say. Personally I really dig the McClicky switch as I like the smoothness. They are tough too for a clicky switch.OReceived it... Once the CBA IIIs at work are free, I can do some runtime tests. I need a data logging DMM...
Don't like the tail switch though. It's 3 modes but changes on a simple tap rather than the deep throw on others (in momentary on)

First current check with Haiku 219.
Using AW 16340
23. 78. 415.
Using 2x Eneloop
27. 106. 630.
Funny though, the Mule 219 and AW 16340 pulls harder on high (690mA) but same on low and med.

Lithium based batteries are preffered for electronics, because their voltage stays rather stable under load, while the one of NiMh drops with the load.
With a low or medium draw, the voltage probably stays somewhere near the working voltage (should be 2,4V) for the 2 Eneloops, while it drops at the high load. The 16340 should keep around 3,7V on high, could be higher on low and perhaps also on medium.
According to my theory, the draw on high seems to be the logical one however, while the ones on low and med should be higher for the Enbeloops (35 and 120 mA). That's theory though and it never works that way in reality...
I know that in led lights they [lithiums] are preferred because their operating voltages are the most simliar to that Vf of most leds. Thes less voltage transformation/bossting a driver has to do the more efficient it is.
