Teflon tape has never worked well for me (i.e., it just shreds). You could try a teflon oil, but I usually just use standard lube. It helps, but I don't know that you will ever get a Ti light of this size to turn smoothly single-handed (especially if you have grip issues).I have a question for those of you who have the Ti - the threads on the head are "gritty", which I expected, but it's bad enough that it's really hard for me to twist on and off one handed (I also have grip issues, so maybe it's just me). What is the best way to treat the threads to loosen them up? I've seen people re-lube with silicon grease, teflon tape, etc., but I wasn't sure what works best with titanium. If anyone could give me any suggestions I'd appreciate it.
Sure, that happens on this light - see for the runtimes for the pattern of slow-drop off over time as the battery is exhausted.The output doesn't even get lower as a sort of warning indicator?
