There is something I absolutely hate about this light that I have yet to read in a review. There is no grease on the threads. It makes high pitched squeaks and metal to metal noise for the full 1 1/4 turn to on or off. The lack of grease (and it “feels” like lack of o-ring) make the head twist too freely. As in it’s very loose unless tightened all the way in either direction. Both issues could be easily fixed with a dab of grease if I could figure out a way to get the head off without damaging the it. The bezel seems to be glued on. I cant get it to budge.
