Fireflies Brass 1.5V AA / 1.2V Ni-MH AA Tail-Switch EDC Flashlight

Anyone know anything about this light?: https://www.ff-light.com/index.php?route=product/product&path=63&product_id=82

Sort of an unusual design with the cut out on the side. I guess it is for the clip? I wonder what the driver is like. Probably just the same poorly spaced, visible PWM one in the SS AA, but it would be nice to be wrong :).

That looks like one I ran across a few years back. If it is the same, horrible low frequency PWM and one of the switches with compression contact to the spring and not really reliable. I will dig around and see if I still have the light. Fireflies was not the original brand.
