Sorry for my very late reply, MascaratumB . Somehow I didn’t catch the reply in my subscription list. I appreciate your response. I had ended up getting an Aurora A8, which I enjoy. However, the noticeable PWM at low levels has tended to annoy me. The effect isn’t the worst I’ve seen, but none of the other lights I own exhibit this effect… which makes it stand out more. I’m glad to hear the E300S doesn’t have visible PWM.

I’m wondering about the optic. Is it a 20mm size? There are a number of variations in optics available today and it’s interesting to consider an optic swap. The difficulty you faced in disassembly is a bit unsettling, though. Especially where that top seal is concerned. It does sound like it’s necessary to do it, though, to keep the pill from moving when rotating the outer bezel for access to the optic.
