I discovered the clip being the answer to the headband issue by accident and posted it a couple days ago it does work.

1802

On the thermal configuration example. He did 9 clicks, then 40 clicks. What does each signify?

He said 30 clicks would give 60 C… He actually did 40 clicks which would be 70C or 158F. Is that too hot of a ceiling?

That’s Anduril only correct? I have a couple that are older Narsil M. Is the procedure different?

TIA

Just your ISP in this case.

Works fine for me.

1804

I deleted my post - just came up for me, weird - maybe you triggered it . Been trying a bunch of refreshes, nothing, til just now -- weird.

It’s New Years Eve. Servers, digital bandwidth, internet traffic… today is the busiest day of the year because it’s a world wide holiday that goes on for more than 24 hours

PS. Happy New Year!

1806

To celebrate New Years, I ordered my third PL47.

1807

I noticed both the PL47 and ROT66 are no longer available in 219B. Sounds like any remaining stock was diverted to the E07 and we are reaching the end of the line with 219B lights from Fireflies.

…and we’re up to 44 days in transit for my 219B PL47.

1808

Fireflies should start selling additional tubes to BLF members who are having problems with the initial tube.

1809

/\ Yes

1810

The tube is the problem, it is not the battery.
I received two PL47 with Nichia 219B and tested with the battery (Sofirn 21700), and the black one is good, but the champagne one battery doesn’t fit (does not go in).

1811

Inner diameter of the tubes :

XPL Hi V3 3A 5000K Champagne : 21.69 mm
SST20 10W NW 4000K CRI95 Black : 21.96 mm
Nichia 219B-V1 R9080 Champagne : 21.72 mm

1812

Inner diameter of the tubes :

Nichia 219B-V1 R9080 Black : 22.0 mm
SST20 10W NW 4000K CRI95 Champagne : 21.7 mm

M4M4X’s review is worth a look for anyone thinking about buying one of these, or having problems.

See video review: Fireflies PL47 and E07 // some more vids added

For the want of an extra few mm of metal, or a little research into cell dimensions and thinking about tolerances when designing the metalwork, this project seems to have been a fail for some.

As for the electronic/firmware design and integration, well it’s early days yet to know how durable the LEDs will prove to be.

Fundamentally a torch that (unmodified) can cook itself in a minute or less, along with any other failings, is a bad design. It’s not the user’s fault, nor the fault of the dumb cell (that may or may not even fit), it’s just lack of design, integration or development testing, never-mind independent review. Also entirely predictable, given the hardware and firmware capabilities and limitations, when constructing such an over-powered device with so little thermal capability.

Between the manufacturer, the electronics and the firmware consultants, a way should have been found of controlling this beast. And I don’t mean just shipping it in muggle mode with temperature control set to an unusably low level. Still, it comes with a multi year warranty, so no need to worry :cry:

Any such ideas would probably also be usefully applied to e.g. the FW3A, though at least that one should be able to mostly run purely on 7135s, with the FET kept only for special (short) occasions.

What is certain is that changing LEDs, should it be required, will not be easy, this torch seems to be purposely designed to frustrate hardware modders.

With these small, hot, thermally challenged, multi-emitter torches, with the output power of a Q8,

Edit, or nearly twice that, in the maddest one. Seven emitters WTF? What could possibly go wrong ? does this seem like a plan ?

Just because you can make it, and persuade some people (noted) to prostitute themselves to try to make it work, after a fashion, does not mean that it it is anything that I desire. Absolutely the opposite.

Thermal control is probably the most important challenge for hardware and firmware designers. And frankly I don’t think the way it is being approached at the moment has much merit or future. Nevermind requiring the user to fiddle about with it themselves.

This is where the effort should be being applied, rather than just titivating switch and aux. LEDs, pretty though some may think them.

Please use calipers to measure your batteries. Some are just over 21mm wide. That’s not the fault of the tube. They get rewrapped and resold. I have many like this.

1815

This is not new. Manufacturers of 18650 torches do not make their tubes precisely 18mm internal diameter, or only designed for 65mm long. They take a view, and make things that mostly work without complication for the user, except in extreme cases (mostly “protected” even “button top” cells with all the extra unnecessary junk added on, and sometimes even a second wrap over the original.)

Nevertheless these sloppily toleranced torches are made and suit their customers very well.

Possibly a “wet behind the ears” junior designer sat down at the CAD station and drew something up assuming that all 21-70 cells would be no more than 21mm diameter or 70 mm long.

Schoolboy mistake.

1816

Light arrived yesterday,got shipping notice on 11/25/18.
40T works,so does Vapecell 5000 with recessed top.

1817

Not sure where you pulled your analysis from, but I can guess :slight_smile: J/K. He said his two PL47 are inconsistent. That’s a different problem for him I’d like him to verify if he can.

My PL47 tube is 21.4mm at both ends.

My Acebeam 21700 battery is 21.1mm in diameter and fits well.
My ROFIS 21700 battery is 21.8mm in diameter. Really freakin wide battery, doesn’t even have a USB port yet is still that wide.

There’s no way I’d expect Fireflies or any other company, other than ROFIS, to fit the ROFIS battery. The Acebeam literally rattles around inside the ROFIS MR30.

My 18650s vary, however the wider ones are 18.3mm, so they all fit well into the PL47 using the included adapter. The tube is perfect.

He should measure the Sofirn battery(s) and both his tubes with a caliper.

My two PL47 with Nichia 219B tested with the same battery (on one Sofirn 21700)

Now that we have established that you do not desire this light, could we have a reason besides being a narcissist troll why you feel the compulsion to continue blathering on about the light that you do not desire, relentlessly in “woe unto you” tirades.

That is like a redsox fan spending time at a yankees forum just to poke the beehive—just to insult and infuriate, because it is fun for him. That is simply mean spirited and childish, and you keep coming back just to spout off, “i hate everything about this light that i am not interested in and i clearly have nothing more constructive to do with my time than come here and vomit into your brains for awhile. Well honestly, because i am simply a miserable, sad and lonely person and coming here and being hateful makes me feel strong and powerful and alive…”

this is the behavior of a troll. I dont understand why it is tolerated

And shame on you community for allowing this pestilence to persist.

Tiresome.

Can you measure each tube inner diameter in mm like I did? Sounds like they are somehow different.
