I'm not sure if it was pure PWM or not but when I do a run time test, I sample once every 4 seconds and if the output is up and down (even if your eyes don't see it), it just makes a mess out of my chart. I guess I'm too much of purist when it comes to driver design.
I'm not at my computer where I can check the run time chart but from what I remember with an AA, the efficiency was pretty good. It's really not a bad light. I shouldn't diss it too much. I'd buy another on a Lightning sale on Amazon. Hard to beat it for the price.
