Hi dd61999,

Thanks for the runtime graphics for the Zebralight v Fenix using the Energizer e2 Lithium cell. The results are quite interesting. The Fenix L1D Q5 (Hi) is specified at around 107 Lumen according to the Fenix Store website at

Do you know if the Zebralight has a higher output higher than the specced 66 Lumen on the Zebralight website when using Lithium Cells. Comparing the two runtimes the Zebralight looks to have an output of around 80-85 Lumen (relatively speaking). This would make sense as a lot of flashlights run brighter with the Lithium Cell when compared to the NiMh cells. This would account for the shorter run times than I would have expected at 66 Lumen.

The Zebralight looks like an excellent performer and when looking at the numbers and comparing it to the Arc AAA premium we have the following;

Arc AAA Premium - 8.9 cm cubed - AAA Lithium Cell - 1250 mAh @ 1.5 V 1875 mAhV - 10.5 Lum 5 hrs

ZebraLight H50-Q5 - 16.8 cm cubed - AA Lithium Cell - 2900 mAh @ 1.5V 4350 mAhV - 18 lum 20 hrs

The ZebraLight is roughly twice the size but lasts 4 times as long at nearly twice the brightness on the medium output setting. That IMHO is pretty impressive compared to a already excellent product such as the Arc AAA Premium and especially when considering the Zebralight has the 3 different lighting level options as well.
