You need a CPU heatsink and an active cooling fan if you plan to run an XHP70 at 6000lm, unless you’re comfortable with your LED going over 85 or 100C and having reduced output.
Yes, a user-friendly design is crucial. I have another question. Will there be enough room in the driver cavity for an optional driver change? I dont need much, just hope it will not be designed like the Palight Boss1 with 9mm of vertical space in the driver cavity.
It will have some extra space, I think I asked for 15mm for the first render, it will be adjusted before production I am sure though.
Just give it an extra 100 or 200mm in there so we can store a sandwich and drink too!
Could do that and basically create a modern maglight so cops everywhere can carry a big stick and not get sued lol.
Haha I still have a 4D maglite sitting around somewhere from back when I thought those were “high power” flashlights….
Because 4D must be brighter than 3D cells, right? xD
Sign me up also depending on final price
why we keep using 18650 at this size?, 4s 26550 would be better in my opinion
It was mentioned earlier, people want to be able to hold the thing.
26650s would require a handle to hold it, and at that point they may as well do the box design they originally had in the vote.
More people voted for this style of light, so that’s what they’re going with.
Also, more people own 18650s.
I was the one that brought that up earlier. I meant to jump back in and clarify that I meant 4 26650 inline like the L6 but nearly double the length, not a 4-26650 side-by-side box. The box design doesn’t appeal to me either but if the 4 cells were in a nice straight line it would be about the length of a 4 cell Mag but WAAAY cooler.
Interesting idea.
Tube would be much thinner and runtime would be shorter tho.
There is a solution to use 26650s, but that would mean 4 in series, in a bored-out thick long battery tube, and from what I understand that’s not wanted by the development team, and really that’s who’s calling the shots in the end. So like I’ve mentioned before this light will not suit everyone . If you don’t think it is for you look elsewhere. There is literally no one single light to suit the 100th percentile of users, this one is not that magic bullet either.
It will be a specialised long throw beast. Not your EDC that Jim, Jill and John will want for late-night fridge raids.
Members new and old in a sense insulting some aspects of this light should be thankful they’ve been allowed to view it’s progression in the R&D stages. And also have their opinions on it heard.
Today’s 2cents.
Edit - that first sentence or 2 was being typed the same time as other members. Sorry for repeating your words (-:
Not necessarily. Bore out a fat tube to accommodate 26650 width. Yes it would weigh a lot due to very thick battery tube walls - but it’s going to anyway.
But in saying that you’d lose 2 carriers and 4 cells. So the weight may be ok.
Please add me to the very interested list. I can’t miss out on another potential industry stand setting BLF creation.
Ahahaha! Idiocracy… a documentary!! I’ve been saying the same thing for years. I call it the “idiocracy effect.”
I work on a plane and have to make an announcement on each leg regarding the Samsung Galaxy Note 7. Even though they have been recalled, and the replacements have been recalled, and now they are banned by the FAA from every flight in the U.S. Some people are still using them and sneaking them onto planes.
Li-Ion battery fire/explosion onboard a sealed pressure vessel probably won’t end well. You can’t just pull over and park. This is the idiocracy effect in action.
And yes, because of the “idiocracy effect” now prevelent in our society, perhaps PCB fuses are a good idea.
Cells, capacity, series, power and availability…. what do we mostly use, a 3000mAh 18650? Maybe a 3400mAh? But we’re talking about using 4S, then 2 parallel, right? What about the big 32650? It’s in excess of 6000mAh, delivers whatever power any other cell is capable of and then some (yes, it’ll outperform the 30Q or LG HE4) And 4 inline series would make (does make) a great handle for a honker.
The beastly Trustfire TR-J20 uses 3 of these, I’ve helped build one that utilized 4, and the results can be staggering. It would have the full capacity of 8 18650’s, with the expense of 4 good cells. Something to think about, I’m sure most would want to veto based purely on having to buy those 4 new cells, but doesn’t a light like this warrant a set of matched dedicated cells?
Edit: Just so you know they’re serious contenders, my TR-J20 uses 3 TrustFire 32650’s and puts out 15,000 lumens. Richard built one that needed 4 of the big cells, I built him an extension for the TR-J20 he modified, and it made a whopping 34,000 lumens! These cells are awesome!
Beamshots!!! That’s just insane power
4 x 26650 inline!?
Comedy. The tube will be too thin. And the proportiins would be horrid.
26650 can be used in a 2x2 configuration. With no carriers i think.
As I mentioned up a few posts but you keenly overlooked, all that needs to be done is bore out a fat tube to fit 26650s, and have thick tube walls. The weight of the thicker walls (by rough calculation) will be minimally more than the weight of the 2x carriers and 4x extra cells that will be housed in the 18650 configuration.
Or if weight is truly an issue, bore more aluminum out, and make a plastic sleeve.
well, 4*26550 is quite big, but how’s about 2s 26550, it’s thick and long enough to not be an idiot looking
and today many people have access to 26550 cell, if you want to make a flashlight for everyone, you need to stick with AA ni-mh battery
but, the vote has decided 8*18650, so, nothing can do now
A changeable Tube would be better, for those who dont have and hate dummy cell
