I appreciate the threads being a bit stiff in a twisty, makes it less likely for the head to fall out at some point. But too stiff is not nice of course.
Geuzz: thanks for sharing your experience and opinion with us :+1:
Concerning the twisting action: we got what we asked for, as the threads are an exact copy of the Fenix E01 (C01 and E01 can âlegoâ), the twist resistance of the C01 is a deliberate design decision and carry-over from the Fenix E01.
After reading your post I just tested the twisting resistance of my golden and purple Fenix E01. The golden one E01 is even more stiff than all my four Sofirn C01s, while my purple Fenix E01 is slightly less stiff. Strangely enough, the golden E01 is was one of my most used lights (I carried it for over a year on my keychain, untill I received my Sofirn C01s). I can still operate all of them single-handedly, so I do not perceive any stiffness as a problem. Like djozz said, if the twisting action is too smooth, chances are higher to loose the head during everydaycarry. Perhaps also the length of the battery might be a factor in âstiffnessâ of the twist action.
Funny to read your kids took it to bath; my kids did as well, and they really enjoyed its waterproofness. :partying_face:
I have other lights where my kids did the same, which lead them to observe: âLook dad, there are coming bubbles out this flashlight.â :person_facepalming:
The only thing I can add is simply to make sure the lube is on the o-ring, too. Thatâs actually the most important place to lube.
I think when the FW3A starts shipping, Iâm going to order a triple SST-20 board to compare to the stock emitters, and also some spare SST-20âs of both 3000K and 4000K to play with (Iâve got a couple E05âs that are definite candidates). I look forward to comparing them. Currently my only other 3000K flashlight has a 90 CRI XM-L2 in it, which the Yujis are clearly better than.
It makes perfect sense to me. Low enough it can be reasonably used as a bedside light, but bright enough it can also be useful at short distances when your eyes arenât dark adapted yet.
Yes indeed, make sure the O-ring is lubricated.
And anyone know whatâs the O-ring made of, so we can choose a lubricant that wonât make it gummy?
O-rings can be made of lots of stuff: O-Ring Material Chart Rubber Selection Guide Quick Reference
Which shipping method did you choose? Itâs kind of odd that nobody in the States has seemed to get their C01 yet, but somehow you got a light, albeit the wrong light, in 18 days. Mineâs still in China!
Thank you for that link hank. I have used SuperLube exclusively on all my light threads & O-rings for many, many years & never had a problem. Never a gummy O-ring in all that time either.
BUT, I had never seen that chart you linked to!!
It does seem to cover it all⊠:+1:
Dang, I missed that when looking at the chart. :person_facepalming:
Silicone rubber (FMQ, PMQ, MQ, VMFQ, VMQ) / NC
ButâŠâŠ Seeing SuperLube is all I ever use, I cannot imagine not having used this on Silicon O-rings at some point. So I will not be changing anything. SuperLube has worked flawlessly for me since my first AA Maglite till now. That is a lot of years & a lot of lights.
If it ainât broke, donât fix itâŠâŠ that is my theory. :+1:
BUT, I also am gonna get some O-rings I know for certain are made of âSiliconâ and see what happen when I use SuperLube on them.

âŠâŠâŠâŠ. Sorry, I couldnât figure out how to post the chart so I had to improvise by âcopy & pasteâ. ⊠Oh wellâŠ.
Hmmmm, I donâtâŠ. but I actually never thought about it either. :+1: It sure couldnât hurt, I think Iâll give it a try & start lubing those O-ring grooves.
