If TN42 had 25% bigger head it would look even better. The Courui has the perfect proportions for a light, and this BLF MT will have very similar proportions to that! Design wise if it is close to Courui in design, or eve a box design it will be great. Those plungers with narrow handles look horrid. Everything else should be fine.
I’m interested.
Count me in for one unit please.
Agreed, if only my courui was properly modded - sad really, my favourite looking flashlight, and yet since I got my sniper I never use it…………….it’s just so under powered.
I know the project has started with a roughly 120mm reflector - but could you clever guys not just mod a ‘host’ courui and make it actually work like it deserves to?
Seems to me it pretty well ticks most boxes already, it’s just the terrible performance that needs sorting. I know there was an issue with some peoples reflectors, but of course there is no guarantee that ‘any’ bulk bought reflectors will all be good.
Anyway, just an idea 
David we understand this is will not have the same appeal as the Q8
For lights with a reflector you say there is ample choice.
This is going to be an extreme flooder surpassing the TN42 at a lower price.
I really hope you will still engage as you did with the Q8 even though you are not liking what it could be looking like
I fear the reflector, driver and LED alone will costs manufacturer more then $40 and we need a lot more material for the housing.
When form factor and LED are choosen we will do a rough calculation to see what this one would cost (as was done with the Q8 bit that was much easier to guess 
)
I like the way you're think'n! Also like your user pic 
.
Betta a 3D drawing could be whipped out in no time by 5ar. Little more than $40 though - big head, more $$$, just the reflector alone - they get pricey in large sizes.
The Miller, I have a confession to make. :person_facepalming:
I’m engaging in this conversation even though I don’t even like “throwers” in general! At least not the way guys around here define “thrower”. I’m really just a middle-of-the-road kinda guy when it comes to flashlights. I like Neutral tint. I like a “neutral” spot as well. What I mean by that is that I don’t want a flooder OR a thrower, but something in the middle. If anything, I’d rather it be more thrower than flooder, but that’s all. I don’t have a real use for throwers. I don’t hunt and rarely am in a large enough un-lit area at night to need to see further than say 100 meters or so. I know flooders can easily reach that far, but I don’t like spilling too much light on things to the side, so bringing it in a little makes sense to me.
That being said, I do like to “play around” with lights that can reach out. I have bought lots of zoomies, and I like to see how far the fully-zoomed-in spot can reach. I’ve got a Courui D01 (well, actually, it’s my daughter’s) with a de-domed XM-L2 in it, and the rest of it is stock. It is plenty of “thrower” to me. So, what I’d like to see is the same throw as that, with a wider (to me, more useful) hot-spot. If I had a good quality light with a 120mm or greater reflector, I’d want to put a large emitter in it, like a MT-G2 or XHP-70, or even that Luminus SBT-90 that I’ve got collecting dust in my basement/shop. The balance of throw-vs-flood would be just about right then.
So, you guys can safely disregard everything I say when it comes to designing a BLF mega-thrower. 
I keep not getting emails about updates to this thread….annoying.
I had suggested this at one point but I think it got lost or maybe it was in the big post that I lost at one point and gave up reposting lol.
This was actually my thinking fromt he start, use the Q8 as the base design since it is already well setup and simply cut it off at the shelf and then make a new head for it.
The bulk of the work is already done. Although we would need to figure out the cell setup, see next reply….
This is something I would like to see as well but it would be hard like you said. The only way you would get 1S is if we either used cell carriers or an extension for the battery tube, which would be nice to have for the Q8 anyways actually. Although alignment would be hard to say the least.
I think that cell carriers would make the most sense. You could run any cell setup you wanted and cost would be minimal, you could simply use a modified version of the multi-cell Q8 tailcap in the cell carriers.
It would cost more naturally but should easily be able to be kept under the goal $100 budget (I think that the total cost could be lower then that if the Q8 was used as the base).
Also, for the record, the CAD designs of the classic style light in the OP are using the correct proportions that a final ~120mm reflector light with a quad cell setup would have. So that gives you an idea on the final look of such a light. I think it looks good personally.
That said I really do like the box style, I just think it would be better utilized with a multi-emitter mega lumen monster setup. 7x+ XHP70’s with 35,000+ lumen and a fan cooled heat sink to actually handle the ~400 watts of power for a reasonable time anyone? Um, yes please.
Again here is a simple design using a 120 mm reflector. (just so you can see how it would look)
Head is 130mm, tube is 50mm and total lengt is 261.5mm
Here it is with a shot tube. (like the Q8)
Honestly for a single emitter, we don’t need anywhere close to that much fin area. The surface area of the head itself is already huge.
We do need space for the side switch though.
True while we don’t need that much fin area, it also doesn’t add much space, they could be cut down for a sleeker design though but I am sure he plans to do something like that in a final design.
I’m just thinking from a weight standpoint. Djozz likes light, that looks heavy.
Look at the TN42 for instance. It has almost no finning, and handles it fine. This hot rod would be doing like 7watts more than theirs?
True but they also have far better thermal regulation then we do but I see your point.
That said I am sure some people will be swapping XHP70’s into this (should actually be quite nice with that large of a reflector) and then it would need every bit of cooling it could get. I think some more mild fins along the lines of the L6 would work fine though.
Too few fins and it gets that ugly plunger look IMO/
it’s all about the transitions. The TN40 is hideous because they just stretched out the top. The TN42 is beautiful IMO. I really like the smooth head close to the bezel. You should go with fins on the sloped sections.
I was personally thinking of something along the lines of the S70/L6 style, something in between would be nice I think. Mostly cause I don’t want to just straight up rip of Simon or I would say a larger L6.
I’m in. Would prefer plunger style with 6 or 8 batteries,for run time and any xhp led. Seems like we’d be going backward with any of the older leds. But anyway I’m in for one whatever you all decide. Will enjoy seeing this move along. Wish I could add something smart or interesting but alas I’ve got nuthin….
I’m interested as well. Would love to see 110-120mm head diameter, with an XHP-35 HI and powered by either a 4S driver regulated up to 2.5-2.9A (or a buck to have 4Sx2P at the same amperage); or a 2Sx2P boosted driver, boosted up to 2.5-2.9A, for which I know currently does not exist.
Have two big lights with long handles, the Fenix TK70 and the Supbeam X60, neither has ever been used except for testing because of their size. The second one with the short handle looks very unbalanced.
Who holds a light at eye level, never done that and never seen anyone else do it.
Ok, ok. :person_facepalming: Add me to the “interested” list.
Is a head band going to be included with this light? :laughing:
