Lou Minescence
Flashlight Enthusiast
The PD31 specs may say 2 lumen but mine is more like 10-15 lumen, owning a PD31 I don't see why I would buy a PD32 but it seems the lows are pretty much the same except the PD32 specs may be a little more accurate unless my PD31 has a unusably higher low mode than others.
I think my PD 31 is around 2 lumens. I run my light on 18650 batteries.
