Yes tests prove it is possible BUT we specify is at 2500 lumens better to underspec as with the Q8) AND it won’t sustain it for long because it will be too hot, a default step down will be chosen based on testing, of course with Narsil, people can set up thermal stepdown for themselves (calibrating the MCU in the process via a vey simple menu (choose thermal stepdown and the light turns on at max for user to decide when it should kick in, very nifty! not by default for each MCU is different so a careful (say 30 sec) stepdown will be default so it is safe to use.
This sounds great, I’ve been on a fairly long hiatus from BLF, I was previously considering an E14 or S41 (my plan was to mainly use it with the optional 18650 tube) also looking at the S42 but after reading about all the issues going on with all of those I held off. Real happy I waited, and came back now to find this beauty!
I may reconsider the S42 (219c) when the revised versions arrive, to use in 18500 format.
Yes well put
Driver design is being tweaked now, it is a complicated driver with the ring for eswitch in tail and relatively large MCU on a small board but is seems almost ready.
Yay!
Really looking forward to this light!
Please make sure nothing is glued in the final version. That way we can do driver swaps or upgrades in the future.
The driver will most likely have another firmware option available after release. I plan on doing a thing with it where you configure it by pointing it at a screen so it can read Morse code. I’m not sure how useful that will be in practice, but it should at least be a fun project.
TK, yeah in the design this future firmware is taken into account. Could e sweet, choose the setup of your light on the pc, hold light to screen and it gets the setting one prefers.
lot of work, for the pc/smartphone user interface and firmware are to be made, so nobody would expect this to happen soon,
the mere fact you are checking in on the driver development is already very cool!
My limited understanding is that with an extra component on driver the led can be used to detect flashes of a screen.
In a special config mode in the firmware one should be able to program the light using the flickering of a PC or smartphone screen
Hah, no. It has three LEDs in parallel, not a camera.
So, it effectively acts like a single pixel, and can only sense a single pixel worth of information. It’ll have to talk in blink patterns instead of QR codes. And since the screen can be just about anything, it’ll probably be pretty slow in order to make it compatible with a wide range of devices. DEL modified the circuit a bit to make it work, and figured out a way to somewhat amplify and center the signal to improve sensitivity, but it’ll still be a pretty slow one-directional data transfer.
It’ll probably be useful for people who build and sell lights, since it could eliminate some of the need for reflashing. For example, it might be possible to configure voltage calibration from a phone. But for most people it seems like more of a gimmicky novelty. And it could easily go too far and make the thing brickable, so it would be a bad idea to put it in receive mode at a disco party.
(I’m planning to give it at least some minimal data verification algorithms, so accidental configuration should be unlikely, but it’s not exactly going to crypto-sign and checksum each transaction)

How would this be possible with 3 x xpg3 led emitters?
Yes tests prove it is possible

I may reconsider the S42 (219c) when the revised versions arrive, to use in 18500 format.I am stoked for this light. I love the idea of a light that looks straight from the lathe, and kicks butt to boot!
Really looking forward to this light!

Yes will update list later
Indeed glue is not an option

Oh that is pretty…
Please put me down for 1…
Please add me to the list.
Thanks
I’d like to get one please. Thanks.

Beautiful!
Please add me to the list for one.
BTW I really tried to resist…
In for 1. thanks
Please add me to the list for 1 light. Thanks!
Hi Miller,
Can you put me in for two please? Many thanks.

Oh, and I should probably be on the list for two instead of just one, so I’ll have one to use and one to mess with.
Put me down for two please.
Wow, yes will update the list later.

How about (Advanced) QR-code?
You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.
