My PL47 just hit the USA. 17TRACK showed it as not even received from the seller on the China end all this time. This is how bad overseas tracking is. You have to be patient. Then there’s the slow cargo ship that got caught in a big storm, my flashlight went overboard, got swallowed by a kracken, he shat it out, a dolphin found it and used it to light his way to Nova Scotia, he passed it to some Canadian geese who used it to light their way flying to Florida for the Winter, they dropped it (butterfingers) over the harbor in NYC, it landed on a pimp who traded it for some rock candy with a lady who also works at a mail sorting center, it then fell out of her pocket and got scanned into the USPS shipping system and now I have some tracking finally. Whew. Look at the positive, at least it’s tested as working

Go for a e07 and use 40t.
Pl47 should be fine with 18650.
Just received mine. At first it worked fine, but after I unscrewed battery tube and screwed it back, flashlight stared on turbo and can’t be turned off. The only way to turn it off is to unscrew tail cap. I tested with LG 21700 which i got with the light and Sanyo GA with the adapter.
Any idea why is wrong with it?
It’s in the PL47 config file, but if I recall correctly I think the default ceiling is set to ramp level 120 of 150. And I think that works out to about a 30% to 50% of the full lumen output, but with all the nonlinear response curves involved it’s hard to say exactly without measuring.
If a light is in full turbo any time power is connected, that usually indicates a short somewhere, allowing current to bypass the driver and go straight to the LEDs.
That makes sense, I guess I should contact Fireflies then.
Thanks for the fast response ToyKeeper .
As you guys know, skylumen have two dead pl47. FYI
Any details posted about that somewhere?
It may or may not posted… I communicate with him on the Facebook messenger.
I bought the XPL Hi V2 3A 5000K Neutral White. I’ve been reading about some battery restrictions for the Nichia 219B. Other than some of the size issues are there any amp issues? Can I use an EFEST 35A for example?
Finally received my lights. After being held in my local postage service for a week.
Had that same feeling too! Red led ?

The red light in the center is a warning that the voltage is low.
It happens when unscrewing the light because, for a very brief moment, the voltage passes through the “low” range before it hits zero.
It also happens when the battery is genuinely low.
Nice feature!
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.
