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

lighted tail switch could be a possibility too. maybe Lexel could chime in on if that would require a bleeder or if it’s good to go as is.

I missed out on the X6 - is it still for sale anywhere reputable?

As far as i know it will be Bistro OTSM.
But we are trying to get in contact with Lexel for the last few days. Via Forum and via Skype. Because we need some information for the manual (regarding his driver) and for the website where the lights will be sold. But no answere.

Which LED should throw farther? I see that the SST-40 has a bigger hospot and more lumens.

The XP-L HI should throw further, no dome. Same size die, the lack of dome should nearly double throw all other things being equal. The 40 will carve that down with brute strength but of course it will take significantly more amps to do so, compromise all over the place.

I have some questions:

1) What’s the difference between Bistro and Bistro OTSM?

(I know the BLF X5/X6v2 aka Astrolux S2/S3, CPF Italia Cometa and Mateminco X6S use Bistro, but are there already other commercially available flashlights that use “Bistro OTSM”?)

2) What are the estimate beam distance throw (candela) for the SST40 version and the XPL-Hi version? (shouldn’t these data, even if just estimates, be included in the specs chart?)

(I notice XPL-Hi is V2-3B, any reason for choosing 3B over 3A? I think 3A looks more rosy while 3B looks yellowish, at least as per my experience when comparing Astrolux flashlights that use XPL-Hi 3A and 3B)

3) Would there be a danger of burning out the SST40 LED if using a high-drain battery like 30Q or VTC6?

Yep, always that compromise. I bet a dedomed SST-40 would be quite the thrower.

I’d also be interested in knowing the approximate throw in meters.

Just a quick interim update:

What's the difference between Bistro and Bistro OTSM?

That's a question only Lexel and maybe some people that have dealt with the Bistro HD/OTSM source code may be able to answer. Again, I strongly encourage Lexel to chime in and eventually give us more insight as it's crucial to finalize the manual. He has been contacted and asked to reply to those questions mentioned before.

What are the estimate beam distance throw (candela) for the SST40 version and the XPL-Hi version?

I wish I could tell you - or even better - incorporate them into the specs chart. However, Jacky is unable to measure accurate numbers as LS does not have the tools for it. They were never faced with this requirement before, working as a 3PM for multiple brands. They are willing to invest into such devices for future projects, though. AFAIK, there was no prototype available yet that someone from BLF/TLF could have tried out. I'm afraid we need to wait for some BLFers to report their results once they received their lights. Another option would be to send out some more ready-to-manufacture samples to people who have the right equipment but I don't expect this to happen at this point of time.

Currently, there are some loose ends to tie up but hopefully these can be sorted a.s.a.p..

I’m pretty sure the different Bistro versions are just hardware related to how it handles the timing of button presses and stuff. I don’t believe it will make any difference to the end user as far as the user interface goes.

I think both version will perform fairly similiar shouldn’t be much of a difference between the XPL-HI and SST40.

Do you mean throw? In lumens the SST is spec’d a lot brighter.

Yea sorry in throw they should be similiar i think.

Sorry guys for answering so late but some personal stuff came up today. Thanks to Lux-Perpetua for jumping in. And i can not say more than he already said about the questions. I talked with Jacky about the option to measure the output. . . but his boss is still not sure if its profitable for him to make their own lights.
If we can make it a success he will be willing to spend more and then we maybe get the infos. But thats something we can discuss if this is going well.
I hope Lexel will answere a few more questions about his driver so we can get everything ready. The factory is working on the D80 right now in night shift to get everything ready for sale. And if everything goes well they could be ready in 4-5 days.
If i can not get the driver information soon the manual has to be printed without them. Not what i would like to do but they also can not send the light out without a manual.

The original FET driver with Bistro showed a glitch when going high power, like a triple or quad or even the more power hungry SST40 ( which can go over 9A). The driver would not hit Turbo but instead would bump down to level one. I believe the OTSM is a revision that corrects this problem for error free use under high current draw. I seem to remember this but could be wrong.

Many of my early Bistro triples and quads in the X6 had this issue and there were a few ways to address it on the original boards, some quite tedious. This, fortunately, should no longer be a problem after Del and possibly Lexel used oscilloscopes to identify the problem and create revisions to the board design.

The firmware is mostly untouched from v1.7.1 flintrock

Modegroup is 4 with Turbo in the regular mode loop, while normal Bistro has MG12 with hidden turbo (long press from Moon, which also works in MG4)

Lexel can you provide a few more infos abou the driver?
1.Polarity Protection Yes or No
2. Overtemp protection and at what temp Or does it use stepdown (timecontrolled and when yes after how many seconds)
3. LVP at what voltage
4. Driver Name FET+5+1?
5. Bistro UI chart 100% usable for Bistro OTSM?

Makes Bistro sound plain and simple, when in fact it’s far from that…

OTSM as explained by Flintrock himself HERE

And TK’s Bistro Manual… the “plain” Bistro

The Bistro normal UI is copied from a listing made by CRX, thanks S. :slight_smile:

1. Its standard Bistro driver so yes
2. standard Bistro Temp setup
3. 2.7V Bistro standard
4. I count 6 AMCs total and see a FET
5. standard Bistro with triple v1.3 plus
