I did a search about this on forums, and I wasn't getting the answer that I was looking for. I was hoping that someone could clear this up for me.
When I was comparing flashlights, I saw that the Preon Revo could run @ 1.5 lumens for 67 hours off a single AAA battery. Looking at the Preon 2, it can run @ 2.2 lumens for 23 hours off 2 x AAA batteries. Comparing the two, it doesn't quite add up. Shouldn't the Preon 2 with the 2 batteries run much longer than the Revo, or does that 0.7 lumen difference in the low modes make that much of a difference in run times? Looking at some details, the Revo is "current regulated," whereas the Preon 2 has PWM. In that case, what's the difference between PWM vs current regulation? And why is there such a huge difference in the run times between the two?
Thanks in advance...
