[♛ FreemeGB] Fireflies PL47 Gen II 4*XP-L/ Nichia/ SST20 Hi CRI 21700 Right Angle Flashlight - ENDED

I just got my pl47 219b. I am not happy with it. I put 10 amp 18650 and the light goes straight to blinking mode.

I can’t switch modes… it stay on low…

How can I reset to factory ramping mode?

did you tighten the rear cap well?

My other pl47 xpl hi 5000k is working fine…

This pl47 219b is no good… aux was off from the factory… i click 7 times to turn it on…

When i press the button, th aux will turn off… then the low mode came on. Then the light switch modes by itself…

Junk junk junk

Here is the video for the pl47 219b. Is my pl47 defective ?

mine had a low mode and it was blinking because it did not have good contact. I have to tighten the rear cap quite strongly. your apparently has a more serious problem.

Yes… i have tighten the tailcap good… the light start blinking every 10 seconds…

I will contact FF.

It gets brighter on its own. Wonder if it is in some kind of test mode. Maybe Toykeeper might know?

How do you guys deal with the warranty?? Do you send the defective light back to china??

From what I’ve read, seems like Jack will just send you a new one. You might have to show him a video to show how it’s defective.

Guys one question please

what's the difference between Anduril UI and Narsil UI please?

You could look to Lexel for an explanation/solution.

I think that he is responsible for the overall electronic design. Basically just yet another derivative FET +n knockoff.

He also designed the aux. LED board but has chosen not to share the details with us.

I doubt that you will hear anything from FF. Communication is not what he does.

The firmware seems to be based on TK’s open source, but not necessarily tailored properly. so Caveat Emptor. As always. Do your homework.

That said, your failure reports suggest basic manufacturing problems, not just firmware/hardware integration issues.

I wrote to Fireflies about my faulty light next day I receive mail from Jack, he asked for a video and said they will send me replacement light. Yesterday I sent them the video and now I’m waiting for reply.

Just wondering, around how much current to push the 219B to give a purplish bluish tint?

How about a full-charged 40T? Will it also give the PL47 219B purplish bluish tint?

Same here last night with my Samsung INR21700-50E fully charged, be careful with nichia 219b turbo mode.

Narsil, actually NarsilM for "Multi" channel output support was further developed/released for the BLF Q8.

Narsil - dates back to 2015/02, vers 1.1 released in 2016/07

NarsilM - v1.0 released in 2017/05, v1.1: 2017/08, v1.3 is the active version

Narsil is the culmination of many inputs from the BLF community with UI contributions from BLF/Q8 members, and software components from ToyKeeper, JohnnyC, Werner and others. I put it all together and added some unique twists of my own. Because of it's rich history and support for many UI options, it's gotten a bit complicated.

Anduril is considered the next generation of Narsil(M). If you are familiar with the Lord of the Rings, Anduril was the sword forged from the fragments of Narsil, so the firmware is very much along the same lines. TK wrote Anduril from the ground up so it's a cleaner re-birth, but with same/similar features. She has taken it further in some areas, like brightness controls over the AUX LED's, campfire/candle mode, etc.

NarsilM has a bit more traction out there right now, more hours of use, maybe a bit more proven, specially for it's uses in the Q8, GT, and associated lights.

I can't make a true comparative list since I'm just not that familiar with the details of Anduril. You would probably find better and more info in the firmware threads. Sorry, I just haven't had the time to keep up with things as I should have.

awesome! Thanks a 1000000

jack replied my email within 7 hours… he asked for the video… I summit already.

I post the video here too. Post # 1672

I dunno - weird, but was the light warm/hot to begin with? Not sure if Anduril has full thermal regulation and not just thermal limiting. It almost looks like it's turning up power after recovering from thermal dropping output. If the firmware doesn't do that, then something weird goin on with the switch I'd suspect .

Looks like thermal regulation is having issues, though not sure this is enabled in Anduril in the PL47??

That definitely looks like a hardware problem, like it thinks the switch is being pressed when it’s not.

It’d be worth cleaning the contacts and trying to remove any potential dirt or debris from inside the light. I’ve had what looks like little hair-like bits of aluminum floating around in some lights, causing problems. But if that doesn’t help, it’ll probably need a replacement.

There is no such test mode. It looks like it’s in stepped ramp mode and it’s getting phantom button presses.

Speaking of doing one’s homework, I’d appreciate it if you followed your own advice instead of spreading FUD. I’ve confirmed repeatedly in public that I made the code for this light and sent it to Fireflies. The code is published, the compiled binaries are published, and the details are available for anyone who wants them. Speculating about it isn’t merely unnecessary; it has a negative effect by spreading fear, uncertainty, and doubt about things which are not uncertain or doubtful.

The PL47 uses thermal regulation, but the behavior in the video is something else entirely. The thermal regulation system doesn’t go that low, and when it makes adjustments it’s smooth instead of going in steps.

There is only one known bug in the thermal code, and the PL47 uses a workaround for it. Sometimes on lights which heat up incredibly fast, the normal regulation algorithm doesn’t ramp down fast enough. So the PL47 errs on the side of caution by using a hardcoded fast step-down (er, ramp-down) on turbo before switching to the normal regulation.

About the link above… TA has been having thermal issues on a light he built, and is trying to get the code to work, and it’s doing really bizarre things… but as far as I can tell, the problems appear to be caused by his own tinkering. I’ve tried to point him in the right direction, but I think he needs me to actually fix it for him, not just give tips and ideas. And I’ve been too busy to do that for free. In any case, it’s completely unrelated to the PL47.

As far as I can tell, Newlumen’s light has a hardware problem, like burrs inside the light shorting the switch… or something like that.
