I recently purchased the Fenix model PD36R. I do enjoy the ability to recharge the light as opposed to purchasing new batteries every time. The dimmer option is also a really great way to balance the amount of light needed in each circumstance. If there is one downfall, it would be the heat generated by the flashlight after a few minutes. It is to be expected however, because the flashlight does get incredibly bright when on at full blast. Since I usually work at night this light has made all the difference in the world for me.
