Re: Wave of Ti Haiku XP-G flashlights(on hold)
Since there is a small O-ring seated in the bottom of the reflector and against the MCPCB, I would suggest not unscrewing the LE when your interest is in the window. What mikes1 has suggested is the approach I too would take. I would also suggest you put a piece of tape on the outside of the window so that you know which side is the outside. The inside surface has a delicate AR coating which you don't want to mistakenly put on the outside. A soft microfiber cloth is reasonably safe on this coating but I have gotten in the habit of not contacting this surface with anything other than a stream of air. :shrug:
