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

Like this, so the flashlight is actually inside your pocket instead of dangling outside.

I’m down with the Skilhunt clip. :+1:

I’m happy as long as the clip remains removable and it doesn’t add any weird bumps like the Manker one does.

Interested. Hoping for a 4000k or warmer color temperature option.

I have contacted Olight in the past and ordered just the clips. About $5 a piece if I remember correctly. Didn’t find them on their site so I just emailed them and they took my info and shipped them. Might try that if you know which ones you want. This was a while back so not sure if they still do that.

Possibly, pending price

Available soon. [quote=Sillen] Possibly, pending price [/quote]

In!!

Valerianis · September 21, 2018, 10:12am

Interested, but which is a price point?

freeme · September 21, 2018, 11:29am

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!

firedome · September 25, 2018, 10:33am

Interested, pending price

PBWilson · September 25, 2018, 11:08am

Any idea what price range this one might be?

AEDe · September 25, 2018, 12:11pm

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

amars7 · September 26, 2018, 10:34pm

Interested pending more info

freeme · September 27, 2018, 11:44am

Mass production has begun.

JordanZHP · September 27, 2018, 3:33pm

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.
