BurningPlayd0h:
Expecting to put an 18650 into a 21-70 torch is just asking for trouble. That’s a 5mm mis-match in length. Even on paper.
At least an 18650 to 26650 adapter is easily done, and respectable in an engineering sense.
Sooo… a 26650 > 18650 spacer is easy but this conversion isn’t for some reason?
The simple solution is to understand the actual dimensions of your batteries before putting them in lights. Since these li-ion cells weren’t ever even really designed to be used loose (and certainly not with varying sizes due to protection circuits, button tops, etc.) that would seem to be the bare minimum of preparedness to me.
I’ve used the included 21700>18650 spacers in two e-cig mods with no issues at all for months until I got some 20700 and 21700 cells.
If you have to tighten it down hard to make contact… why do you think it would be wearing on the springs? Sounds like the cells you have are slightly under spec and you have to get the springs closer by tightening before it makes good contact.
The alternative would be that the tailcap isn’t making good connection with the contact area on the battery tube itself but that would be easy to test by trying it with different cells/spacer + 18650 cell.
Are you sure the o-rings on both ends of the battery tube are still in the correct grooves? I had a similar issue with my Q8 when I got it because they had been pushed into the wrong one when first assembling the light with batteries.
Of the 100’s of lights that I have, this one is the only one I have to really crank down on to complete the circuit. Like I said, at least it works. I do love it but also want it to last. Tried with a short flat top 30Q. With the adapter, too long could complete circuit. Same battery without adapter still needed to crank it hard all the way on to get a circuit. Seems to have something to do with battery tube section making contact with the bottom inside of the tail cap. 50E already showing circular scrap marks from the spring on the negative end. Both O-rings are and have been in correct slots.
Next might try something like a copper O-ring with outer diameter equal to inside diameter of end cap. Not even sure that has a chance of helping. Fine, thin aluminum V-shaped threads won’t last long doing what I have to do to get the light to work. Might ask FF to send another tail. They just shipped my second PL47, with magnet separate this time and second ROT66 a few days ago. Preordered a E07 today so may ask Jack to send another tailcap with that order. ’Nuf complaining…love the light and has a great 3 year wanrranty. Just going to enjoy it and try to stay in the moment!
From some photos I saw earlier, it looks as if FF haven’t used retaining rings for the driver or the tail PCB, but are just relying on contact between the ends of the tube and the PCB surfaces. Perhaps there is no other current path, hence the sensitivity to cell dimensions ?
Since I don’t have one, this is just supposition by me.

Seems to make sense to me, but then shouldn’t everyone with a glued-in magnet under the tail cap PCB have the same over-tightening issue? If not, perhaps there is a flaw in my tail-cap. It will be interesting to hear feedback as others receive their PL47’s.

How is the beam on the pl47?

So funny that there is a “Muggle Mode” spelled out in the instruction manual LOL. First time I heard what Muggle meant, I laughed pretty good.

I like those glowing dice. Tritium ? But they have got to be loaded. Where can I get some ?
The “think of the children” warning is apt.
Are we not all muggles, except for the few wizards ?

nope not glowing, just reflection from ceiling they are made of Ti and available here … https://www.hkequipment.net/product-p/edcdcex2.htm
Neat! I like my Whisky and may need a few of these.

I hate to waste things so I found a use for the rather Sh*te headband mount…
works a treat… I just removed the loop where headband that goes over top of head is…. I found it seemed to get caught on things when it was still present.

What is the correlation between titanium cubes ablnd whisky?

Cool idea! It holds well enough that it’s not aging to accidentally pop out?

pretty solid to be honest and due it’s orientation will be fairly hard to knock it too….
Put them in the freezer and use them as ice cubes that dont melt and dilute your drink.

So, guys and gals, I have not received the light yet.
Do you think I should go for a refund, or not? I’ll be getting my PL47 from Neal if I have to with Express shipping.

I thought so but it doesn’t make sense as I’d be challange to find metal with less heat capacity, right? Sure it looks cool but doesn’t really work, does it?

Did you receive shipped notification from FF yet?

I haven’t gotten mine either. I am sure the Canada Post strike has delayed it.

@freeme and PAvlo, yeah it got shipped a while ago. That’s what happened. Got delayed by probably 3 months by the Canada Post strike.
I wanted to pay for faster shipping, but there were no ways to pay for it on the Fireflies website.
