Fireflies PL47G2 Discussion Thread

Is that a trimmer pot in the center for the aux leds?

There is no trim pot. It’s just the screw that holds the mcpcb.

Just think. Why make a potentiometer that you can’t use?

Assuming this is the Lexel board or something like it, those are probably 0603 color leds.

I wish they’d gone with a threaded bezel. I don’t like press-fit.

Bezel is pressed in, but not so hard as I thought.

So I started with a thin knife.
I pushed knife between bezel and head body from one side.
Then I made the same from another side.
Some space freed up and I pushed a small screwdriver between this parts.
Then changed small screwdriver to a little bit bigger.
Continue doing this until it opens up :slight_smile:

As you can see there are some scratches. They are from screwdriver.

This is not the best way thay you can open flashlight, but the only one in my case.
I think you can use vise or smth like that.

I need this light with amber secondary LEDs. That would be awesome. You choose high CRI LEDs, and add blue secondary LEDs?

If it weren’t such a pain to open the head with the pressed in bezel, I would attempt to reflow amber LEDs in place of the blue myself.

So the o-ring on my black PL47v2 decided to wiggle out of place. No idea how. So I also had to remove my bezel.

After a few tries on the vice, it came loose. No drama at all.


Put it back in it’s place, and pressed the bezel back on again. Perfecto

Also, my second PL47v2 has arrived. The clear ano XP-L Hi V3 3A 5000K version.
Itøs one of thoose rare light I have no intentions of modding. It’s perfect as it is. (I should have ordered a tailcap with magnet, but forgot. So I have glued one on this one…

Pictures don’t do it justice.




Try a plastic pry tool such as that used when replacing iPhone screens and what not.

Plastic pry tool

I’ve been using mine for some time abd it’s definitely an improvement from gen 1. And nice to know that the bezel can be removed without breaking the glass lens unlike gen 1. Dang that clear ano looks damn good. Need to buy another one.

Does anyone know if the firmware can be updated without disconnecting the aux wires(like PL47G1)?

Yes , just need a key adapter

Thanx Fireflies, ordered one :wink:

Anyone experience with flashing the PL47G2?Witch progkey can I use?

Hi, is the ff-light.com website down for everyone?

hi,
I disassembled it to see what package the aux leds are, as guessed by Firelight2 they’re 603 (1608 metric) leds, but I measured the voltage and resistance and it’s a bit strange, voltage across a led is 2.56V, and across its series resistor is 0.96V (10kΩ), firstly that doesn’t add up to the voltage of the cell (4V at the time), but maybe there is some voltage drop from the controller or something.

Secondly the voltage across the leds is a bit high, the current per led is 0.96/10000 so 96µA (which approximately add up to the current drain directly on the cell), the cyan leds 603 that I found should have a lower voltage at such low current (although not that much, 2.3~2.4V)

But if I want to replace with amber leds like this one with about 1.6~1.7V fV at very low current, the resistors should be more about 20k for 96µA (3.5-1.7/0.000096=18750)… , with the original 10K it’ll be about 180µA per led which will drain the cell 2 times faster.

the cyan leds linked are like ~30mcd/mA though, while the amber is ~4.5mcd/mA, huge difference, but the aux leds are originally way too bright for my taste anyway.

Any mistakes here ?

I guess I should either change the resistors, or simply put half as much leds to keep the drain similar (about 1.6mA total at 4V cell), I’m probably going to do the latter, less work and the resistors are 402(1005), not sure I have the soldering skills.

Changing the button led would be nice too, but the retaining ring seems difficult to remove, at least without damaging the switch cap, press fitted rings are annoying…

I had the battery out of my PL47 G2 overnight to charge. Put it back in and noticed the aux LEDs were off and it was in muggle mode. My levels settings had also changed. I thought maybe it reset to defaults but it got way to hot on turbo, probably 70-80C. The temp calibration was off by about 10C. Has anybody else had this happen? Did it just reset to defaults? I’ve had it with the cap unscrewed for days many times and never had this happen.

Any discount codes floating about? And No, won’t order thru Neal’s Gadgets….

Fin has some but you need to request the code via his thread.

Anyone having issues with FF-light? Emails have been getting ignored but weren’t before I paid and the site was offline for some time and no DHL tracking number has been sent.

If you were inadvertently holding down the button while screwing on the cap, this is a factory reset. I haven’t done one so I am not sure if it goes into muggle mode.

Anyone flashed new firmware on the light? Can I use emissar’s flashing kit on this light?

Just got mine in and the pin layout doesn’t match the Emisar programming tool. I wonder if FireFlies sells a programming tool?

Why can’t there be one standard :smiley:
