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

In!!

Interested, but which is a price point?

Lower than ROT66 for sure.

I have some info. The design isn’t set in stone yet, and I hear Fireflies is still doing changes to the host and the clip and maybe some other things. But here are some random observations so far:

  • It’s a right-angle light.
  • Mine has 4 x 219B emitters, so the tint and beam are very nice.
  • It’s about 88 mm long, 24 mm across the body tube, 26.5 mm across the tailcap, or about 40 mm deep at the head.
  • It seems quite heavy for a headlamp, but I don’t have a headlamp holder which fits it so I haven’t actually tried to wear it.
  • The battery is a 21700.
  • The driver is a FET+3 with a tiny85, much like the Emisar D4S. It runs Anduril, but I still need to get a few things working.
  • It has 12 blue aux LEDs and 2 red aux LEDs under the optic. It changes from blue to red at 3.3V, and turns off below 3.0V. Otherwise, these aux LEDs are always on. I’m hoping it can be connected to a dedicated pin on the MCU, so the user can turn it on and off. There is a pad on the driver labelled “aux” with nothing connected, so it seems likely.
  • It also has aux LEDs around the button, but they’re not visible in my prototype. Like the ROT66, it seems to have two blue LEDs which are always on, and two which might be controllable, but on my sample the latter two never turn on. That’s probably something for me to fix.
  • The tail PCB and driver PCB are at extreme opposite ends of the light, with a cell between. The emitters and optics are off to the side at 90 degrees. The switch PCB is directly on top of the driver.
  • The body tube’s threads go rather deep into the head, so it takes a while to unscrew the tube. It seems to also double as a retaining ring for the driver, like how the Emisar D4 is designed… so it’s recommended that you leave the body tube tightened.
  • The button is recessed just far enough to be flush with the edge of the light.
  • I’m not sure how the head is held together, but it looks like the entry points are the lens retaining ring and the button retaining ring… which both look like they might be press-fit. It may be difficult to do emitter or driver mods. However, the driver has Lexel’s flashing pads, so the firmware can be probably changed without removing anything. (“probably” because it’s 2cm deep in a hole, and I’m not sure how deep the pogo pins can reach)
  • There is a magnet in the tailcap, and it is strong enough to attach the light to solid metal surfaces.

Sorry this is all pretty disorganized. I haven’t had a chance to really work on it yet.

Thanks TK

Thanks for the spy report ToyKeeper….

Now I’m officially interested!

Interested, pending price

Any idea what price range this one might be?

It use simple driver not buck boost, and very similar to D4. so my guess ~40-45$.

Interested pending more info

Mass production has begun.

Awesome! Any news on tint options?

Thanks for these details, Toykeeper. Do you know the weight? For comparison, the new Acebeam 21700 headlamp is 80g without the cell and harness, and the ArmyTek Wizard Pro USB model is 65g.

We are so close to completion.

Interested

Wow, 3 days from “the design not set in stone”, to mass production. And 1 month from a facebook announcement with a CAD drawing to full production. We’ve got the wrong companies working on the BLF lights taking 1 to 3yrs.

Mass production also means the specs must be set. Lets hear what they are

wow nice

definitely interested

ToyKeeper is involved in PL47 Anduri firmware. She has already shared some of the details on the driver and light construction.

Full specfication will be made known right before / during launch.

How did I miss this one? I’m IN!

I am finally interested in the light.
