Oh, you could pocket the 26650 model. It is small.
I purchased one of the 26650 models, it is part # P22650-L2 and while it is a very small format and XM-L2, the tint is slightly cooler and it does not draw as many amps, I got just over 3 amps on my best battery fully charged. I have not yet Braided the driver spring (this model has one, unlike the Mini or the D80) so it will probably pull a small amount more, but will not get near the output of the D80.
Now, it is common knowledge that the XM-L2 emmiter’s will draw less amperage from the same driver as the forward voltage required is higher, but the 1.5 amp difference is not going to be eliminated.
One important note on the P22650-L2, the tail cap appears to be glued, have not been able to get it loose. Have not tried heat yet. I wondered why all the pictures given for this model light always showed the battery tube separated from the head and never the tail cap. Now we know why. It is really hard to even tell where the cap threads together but it appears to be on the last cut on the tube.
If anyone has the comparable Palight and has gotten the tail cap apart, please chime in.
If you want the run time, go for the bigger light, but at least with my samples, the D80 is brighter.
They are both have flawless anno and great build so you can’t go wrong with either that you chose.
