The Miller is talking about a 4P. Not 4S
So only 1.2v… I can not believe in 4P AA.

No no not series, parallel
Consider the Q4 the ultimate muggle light and hopefully opening doora to sweet AA yet complex cool firmware running flashlight mods on SK68, Kronos X5, etc lights.
And indeed modded TK4A mini soda can lights needing only 1 AA instead of 4.
The 14500 is neat for those qanrinf max output but 1* AA with Narsil/Bistro is a goal.

You need about 3v (I hope you are not thinking about a xhp in this configuration) for one led and about 6amps for 4 LEDs to get the 2400lm out of it
ONE AA??? Poor small eneloop. Sick after 10 minutes dead Evil

OK im in!

This thread will get 100 or 10000 posts.. I have time

HKJ has tested Eneloop AA up to 10A current. If it takes 2.5X to convert AA to LED running voltage, you’d need 14A input to get 6A output. One cell probably couldn’t handle that, but two might, three sure would, and four would be gravy! The real challenge will be finding a boost driver capable of 1xAA input to ~3V 6A output. I don’t know that any have even been attempted, but that driver has actually been desired around here for a while.

@TheMiller – Firstly, I appreciate all the effort that has gone into conjuring this light and the amount of time and resources you and many others have poured into it. For a conventional reflectored thrower, I truly hope it turns out to be the masterpiece everyone ever dreamed it would be. I apologize if this was the inappropriate thread to mention the Ledil Seanna. It would certainly be a departure from the conventional flashlight build, but I believe it can not be ignored when considering the maximum range potential of the XHP-35.

A quick search confirms there have been several frankenlights already built using the Ledil Seanna/XHP35 combo that approach just under 1 million cd using older binned 35 emitters. Cracking the 1M or 1.1M barrier should be a no-brainer with the latest bins, carefully tweaking the max current level at the bench, a sufficient direct thermal path utilizing a 1 piece integral heat sink, while enjoying the HD version of the XHP35 emitter (more lumens and better beam pattern), which this hybrid “reflector” seems to prefer. In a build using the Seanna, the heat sink should protrude as part of the floor-plate assembly, not part of the bezel. Then the thermal path will be direct and without any thermal bottle necks. The Seanna and heatsink are already proven off-the-shelf parts, easily attainable and simple to mod on a CNC. I think there is enough brain-power in this forum to make it not only highly functional, but also aesthetically pleasing… if not just plain bad-ass looking. The concept and production steps are far more simple than the conventional flashlight, if one has the tooling to implement it.

Unless I missed it, and someone actually tested a reflector + lens + XHP-35HD or HI that beat 1 million cd AND produced a pleasing and usable beam pattern, it looks like the Seanna with the HD emitter will completely murder any other option that I have yet to read about. Im still in for your light if it beats the range of the TN42 in real world performance, and doesn’t suffer the usual myriad of unforeseen congenital problems most other BLF derived flashlights have suffered. So I realize its a tall order with a very difficult path to success. But I think it could be so much more with the Seanna option. Granted, it would be a large departure from the style of huge “flashlight” we are all used to lugging or slinging. Most anything with 4 or more 18650’s is unwieldy by any standards. If you own one or even several dozen chunky lights (as many of us do), you typically chose the light for the task at hand to satisfy the anticipated situation. Among the larger variety, size and weight is usually a secondary consideration… which may be why we own so friggen many of the darn things!!

If this isnt the time or place, please feel free to shelf my blurbs and rethink it in a future project at your option. I hope someone at some point can make a go of it in a production flashlight. Then we can all enjoy something that just might force the flashlight industry to rethink their direction in order to compete with a new level of unmatched performance in this fun niche market. I wont go into great detail, but I have already approached several of the large manufactures to consider unlimited flagship thrower models, featuring pre-culminators that focus spill beam back into the emitter to further excite the phosphor, in conjunction with a Seanna style hybrid Fresnel and variable focal length for beam angle adjustment, removable emitter mounted copper pills for different tint emitter quick-changes and swappable conventional reflector and lantern head assemblies (just to scratch the surface). These are all well proven technologies that have been proven many times on several forums. The obvious benefit of a real heat sinking solution that isolates heat to only the heat sink itself would also be a first outside of the frankenlight world (excluding the extremely well executed and expensive Olight X6 Marauder).

Olight X6 Marauder

If youre interested, here’s a link to the Seanna datasheet PDF.

Concept from M4D M4X:

If anything else, maybe someone else will read this in your highly visible thread and have a go at it.

Thank you for reading.

fund news:

Change:
From:
4 only for progress in projects that are meant to lead to a real flashlight for all to buy.
To:
4a primarily for progress in projects that are meant to lead to a real flashlight for all to buy.
4b the funds are growing so fast, a part also for support of driver developers for down the road these projects can be used in BLF specials

Reason, we do not know what will be used in BLF specials and even Narsil and Bistro started smaller.
Though all developers that are doing their work open source seem happy in doing so, financial rewards or a little donation are no motivations for them. The big projects can get so much attention it seems nice to give others a small token of BLF appreciation making them able to do a Oshpark order or use it for tools or something, knowing they are seen and speeding things up as among others the Kronos projects and Q8 have sped things up too.

A quote from the Q8 topic:

fuzun wrote:
This (Q8 red.) achieves 4000 lumens. For eye perception we can assume its sqrt 4000 which is 60~.

For Q16 I think we should at least double that. This means it will have to be 120×120=15000~ lumens.

Do you think q8’s soon to be big brother q16 with 4 xhp50.2 emitters will achieve this?

Thanks for the donation. I’ll use it to build a couple of drivers for a GAW when I’m finally satisfied with the design.

Thumbs Up thank you for creating BLF tech.
You guys are the core why manufacturers take us serious as a group with real information and input and not just a forum of consumers.
It is the likes of you that are making it possible for people like me to dare ask manufacturers to look at an idea and thus making BLF specials possible, not to mention the coolness of what gets done with super firmware, lighted tailcaps and what not Smile
So thank you again!
Pretty cool you wanna do a GAW! do people who donated to the funds and enter an extra chance?

Nice Mike. You receive a donation for work carried out that you will do more work and donate it away. Smile

So Miller talked you into giving your donation away. I’ll have a few words with him for you and give him a good piece of my mind. He wont be doing that again. Silly

Thanks for the donation, The Miller! Cash

Mike C, I didn’t think I deserved to be on the list of recipients, but you sure do. Your work around here is undervalued, IMHO. Nobody talks much about your contributions, but IIRC you’re actually the guy responsible for a lot of the coolest ideas, like 3+ channel drivers for better efficiency. It’s cool you’re going to “give back” your donation by building drivers and doing a giveaway. It reminds me of Old Lumens in a way. He had received lots of flashlights from manufacturers for reviewing over the years, and he never kept them, but always did a giveaway here.

Also, I want to take the time to say thanks to everybody that donated. I hope you all feel good about the decision The Miller made here. I’ll try to make sure whatever I do is a push forward for BLF somehow. I’ve learned so much in my time at BLF, that I can’t possibly pay back for the knowledge I’ve gained. I wouldn’t even be doing these kinds of mods, or designing my own boards, if it weren’t for the inspiration and encouragement of my fellow BLF’ers.

I’ve already got a GAW going right now (gonna end today). So, in an effort to “give back” my donation, I think I’ll try designing another crazy, cool, or niche driver board. My reasoning is that it’s the guys on the fringe, making the niche items, that push most crafts forward in life. So maybe I’ll find another nifty host and make a driver for it. Then, if the build goes to plan, I’ll do a GAW of the modded light. The donation money will help me buy the board from OSH Park and the components to populate it, and maybe the host to put it in. I don’t know when I’ll get all this accomplished. Perhaps it will be done in time for my 5000 post GAW! Party

Thanks for the donation here as well. if we can come up with a good design for a Q8 lantern I could get it 3D printed for testing.

For the Q16, the biggest issue here will be heat shedding. It will need a massive heat sink.

With 4x xhp50.2 or 70.2’s it should easily surpass 15k lumens, with xhp70.2’s it could get close to 20k or more.

The problem is that it would also be pushing upwards of 200-300W worth of power, which is going to get REALLY hot. So figure it will need to be quite large indeed to reach that level.

Honestly Djozz’s spotlight idea that was tossed around for the GT at first would be ideal for this, it would allow for an active heatsink (aka a fan) and could actually handle that king of power.

Although it would most certainty not be considered “cheap” by BLF standards even if it was the best bang for the buck around.

Honestly, if something, whatever it ends up being; is the “best bang for the buck”…. “BLF standards” may have to possibly change a bit. Smile

Many times quality and dirt cheap do not go hand in hand.
Sure, bargain for the absolute best price that can be achieved and then that is what it is. Thumbs Up

Liquid cooling is way overrated. You still have to transfer the heat to the ambient air and liquid doesn’t help that much. You still need a lot of surface area to do that.

Yeah. While liquid cooling is better than active air cooling it is not worth it because you still need fans with liquid cooling.

I have a different idea.

Did you put pressure on tip of these pressured gas cans before? If you did, you probably know that they make extreme coolness. I do not know if this is practically implementable but think about it.

Here is some science: https://en.wikipedia.org/wiki/Joule%E2%80%93Thomson_effect

If you have a towel and a pressured gas can, try this if you did not. It is very cool Smile

If we want this, of course we would not want Butane or Propane Smile

Look at this: https://www.amazon.com/Crosman-Gram-CO2-Cartridges-Pack/dp/B00GA8S08K

There are refillable CO2 cartridges for air guns. They are available in everywhere, especially in USA! Even though they can be refillable, they are also very cheap.

I do not know cooling performance of these CO2 cartridges in terms of Joule-Thomson effect. These cartridges most likely do not provide enough temperature decrease for these kind of lights. But this is just an idea and we need to fix this heat issue somehow or there won’t be q16.

This Joule-Thomson effect also makes the basis of some air conditioners and refrigerators . (https://www.google.com/patents/US7254959 And I do not know why but it got patented quite recently though.)

While a Co2 cooled light would work it would take a LOT more then 12 gram cartridges (of which I happen to have 175 of them for sale if anyone is interested).

A 12oz Co2 tank should keep it cool for awhile though. A more practical option is to use the heat shedding abilities of evaporation to cool it. I ran some tests and it takes a surprisingly small amount of water to keep a lot of heat cool. As it evaporates it removes a LOT of heat. Although you would then have steam pouring out of the light and have to fill it with batteries and water but it would keep it reasonably cool.

Btw off topic but why would a Texas man own an airgun? Come on man you are not Canadian LOL I thought you are all about real guns, which is a good thing imo as air guns are JUST waste of time.
