I notice that many good D26 sized drop ins are really built for Li Ion batteries. They either have a 4.2 volt max that might toast the emitter with primaries or 9 - 12 volt max that 2 X CR123 cannot fully power.
I wonder which drop in will actually produce the most lumens safely with 2 X CR123. Some have drivers that will UNsafely overtax the primaries as their capacity diminishes. Others simply don't have much output with only 6 volts.
I don't care about flat regulation so if direct drive is safest and brightest that is fine with me.
I expect the one with the most output will be an LED but if there is a 6 volt incandescent drop in with more output on 6 volts that is fine too. The key is you cannot simply look at some of our charts that show max output with 8.4 volts and expect 2 primaries to produce similar output.
This is about lumens - not throw. Cool white tint is fine but not a major criterion.
This IS different from 50 other threads on brightest P60 because I am restricting it to 2 X CR123 primary only.
Any suggestions?
