New WildTrail (former LuckSun) BLF-D80v2 Sale is open.

I remember he tested 45V successfully and 85V did not work reliable

Is a two sided driver compatible with the retaining ring style LS uses? Well, no, actually it’s not, and they just did redesign work to clear this retaining ring from the tube in the tail cap, reckon they could alter the style to accomodate at the driver. Some of this kind of change really impacts the style though, the retaining rings were unique and I liked em , gotta be trade-offs though huh? Isn’t easy being cheesy… :wink:

Yeah, I recall hearing something about that too… but I don’t remember if it was ever resolved. However, I’m pretty sure Mike C has OTSM working on bigger MCUs like tiny1634… so I’m guessing there’s probably a way to do it on tiny85. He says he gets about 15 seconds worth of OTSM with a 47 uF capacitor… and all Bistro needs is about 2 seconds.

I’ve been procrastinating for years about getting the Bistro-HD code merged into mainline Bistro. Flintrock’s changes are far too deep and too broad to be easily merge-able, so it’s a large task. Perhaps I could get just the basics of OTSM working though, without all the other changes. Or I could potentially add some offtime support to FSM, and then the UI toolkit would cover both e-switches and clicky-switches.

Not sure when I’ll have time and motivation though.

I am a bit confused by all the different versions. What do we have now ready to run? And what MCU would we need?
They have way less problems with the Metal parts (they make them in their own factory). So little changes to retaining ring . . . is not a huge problem.
But if we want a BLF driver we need to help them.

I have no problem going to tiny 1634 and programming key for future driver generations of BLF lights

but on this tail ckicky usually a 25V or 45V is more than enough room for advanced code like Bistro

This problem is known for years now
the BLF A6 is very old
I never designed drivers without the 4.7Ohm low pass resistor

I do the fix for years too :slight_smile:
I’m glad you are doing the driver, that ensures a good one and prevents trouble, it would be a nightmare if they attempted to make a driver to our wishes.

Looking forward to where this one goes, while I wasn’t exactly a fan of the style when I first saw it the design sure grew on me when we were doing the BLF Special Edition lights and I still highly favor the beam profile from the reflector they made. I call it a theater beam, a defined yet largish hot spot with low spill… really like that a lot and you just don’t see it often. Hope they keep it similar with the new designs.

I hope that they can find a reflector with tighter hotspot and or less spill. If not i would also be happy with the old one (with 7mm led hole instead of the 9,5 from the old one). But reflector testing is further down the road.

From now on i will update new drawings. . . in the first post. This way it is not necessary to read throu all the pages.

I just used mine last night, and Dale is right, “theatre beam” is a perfect description. I actually also love it, and hope that part doesn’t change. It has a lot of throw outside at night, but the hotspot is much larger than other small, throwy lights. Very useful.

spill angle and lumens are basically only affected by the lenght to opening ratio of the reflector

so with given head there wont be any change in that proportion

Correct me if i am wrong! But with a different curve in the reflector you will get a different beam shape or not?
I think thats what they want to test.
By tha way i updated the internal structure of the head. The stepped design is not happening. Because of the small space between reflector and head they would have to make many small stepps. It seems it is easier to fabricate this form. But we got the bigger mass un the inside + deeper finns and one more. Not a lot but without changing the appearance this is the best we could do.
I hope you like it. And the Tailcap gets a new end. What do you think about it?

I dropped a 3V XHP50.2 in my D80, with a Sofirn FET driver that I had laying around.
The FET might not be the best one, only pulls 9A from a 30Q but it does produce some photons !
The beam is nice, fat hotspot, well defined and some usable spill.
Pictures later

That sounds really good.

If everything goes like planned i will get beam pics from the reflector test next week.
And they will make some short video clips from the machining process when they start with production.
Can not wait to see how the D80 emerge from a piece of aluminium.

Okay I confess I didn’t do any beamshot or pic at all… sorry
Though I did some measurements : 2030 lumens and 20kCd

I need your help guys.
I was asked which CCT we would like to see. They want to offer 2 CCTs. The LED will be a XP-L Hi. Let me know which CCT you prefer in a new D80.

4000k and 5000k.

I would like to see 5D/5A 4000k.
