In Jerommels’ last design, the head is of a TN42 is shown.
This light has a reflector diameter of 90mm, the BLG GIFGA will have a 120mm reflector.
The TN42 uses a XHP35 HI that gets around 2,15A.
The BLF GIGA will get around 2,5A (I hope). Above that, the gain in lumens is marginal but the increase in heat development is considerable.
Due to the much larger reflector and head, the BLF GIGA will have much more mass and surface area and thus will be able to absorb and dissipate more heat.
A few fins around the electronic switch (and so very close to the led) would do, I think.
Bear in mind that using this light outside (remember, search & rescue) means movement which will provide additional cooling as well.
It would be up to the mathematicians in this forum to calculate heat generation, heat transfer, absorption by mass and dissipation at certain temperatures, but do we really need to go that far?
Just a tought: if the BLG GIGA will be well over 1Mcd at turbo, it could have a high setting at which it would still produce around 650Kcd, the same as the TN42 on turbo, so at “just” 2,15A.
I’m sure that the BLF GIGA will be able to handle heat generated at 2,15A for a long, long time. Probably until the cells are depleted.
Most of the flashlights look alike. But some are horrid looking, some are fine. They might have a problem if you make a CLONE, but this is a completely different light that has nothing in common with them. It is like comparing the S41 short, with Skyray king. Yes they are both tube lights… Yes they look similar… But that is it.
My opinion is that TN42 appearance is not suitable for the diameter of 120mm reflector.
It's all well and good on paper but should take care of the production process and the things that can be easily implemented without the production costs increase.
Jerommel: You have to pay attention on proportions: 120mm diameter reflectors, place for a shoulder strap to attach on head, PCB driver size 46mm, driver need at least 10mm of height clearance to the bottom of the shelf, tripod mount .... on tn42 there is no place for the tripod mount if I'm not mistaken (if someone can confirm if I'm right.)
When these above requirements realize I believe that will drastically change the shape of tn42.
Not that easy to pack all the requirements and that looks to be as tn42 or another flashlight
If the overall appearance of a certain size flashlights looks great that does not mean that if you reduce or enlarge the design that he look great as well as the original size. Imagine that C8 increase the reflector at 70mm silly silly silly.
If we decide to design too similar tn42 we will have a problem with finding a company willing to produce clones.
BTW, is it possible to get a cross section shot of your GT render? (it cut in half?).
A blend between the 2 deigns could be just what we need. Personally I LOVE the 5AR design, with a few minor revisions, like the changes miller posted above.
Possibly the area by the switch/tripod mount could be reduced a little to make pressing the button a bit easier while gripping the light and a few fins added at the base of the head to improve cooling. Then make the rest of the head smooth (remove the anti-roll cutouts and fins since that is apparently what people want).
I personally MUCH prefer the overall shape of the GT vs the TN42.
I think we need to forget this “TN42 look alike copy knockoff” and get back on track.
(No offense meant ’Jerommel’, that is just how I see it. )
The renders ‘5ar’ did have been, and still are; perfectly acceptable. They look very good, excellent in fact. IF they need to be tweaked a bit here and there so be it, but the platform is sound & solid.
Soooo, “if it ain’t broke”, why are we all of a sudden trying to “fix it” ? :question:
I think that is a legitimate question, because 5ar’s renders are certainly “not broke”.
Hopefully we will stay mostly on track and see this become a reality. :+1:
As The Miller stated earlier, the reflector choice will significantly impact the appearance. For example, this light (never finished) was for a reflector that was about 120mm deep and 130mm wide. The finned area should be ignored because it is a solid 3". The battery tube was sized for 4 18650 cells side by side. Iirc, 4 cells deep (4P4S). The pic, excluding the finned area, gives some sense of proportion. It's hard to see the final about inch that is covered by the black ABS. That is not the bezel. The bezel would have mounted to that. So the head would have been even longer when finished.
EDIT: That is 6" vent pipe coming out of that wood stove. The bricks are standard sized bricks.
I think it’s good to have some different designs and design features to choose from / to discuss / to consider.
And:
I’m still working on it and i consider everything you guys say.
Please also read what i write along with the pictures.
But maybe i was to soon posting pictures.
That’s just enthusiasm and the drive to make it look ‘less Chinese’.
(no offense to the Chinese)
Then IF it is not ready yet, might I humbly suggest you stop posting a photo shopped “TN42 Frankensteined picture of a light” and wait until you have the real deal before you post it. :+1:
To do different simply “muddies the water” as far as I am concerned.
You don’t have anything to be “sorry” about Jerommel. That is “your opinion”, just as my thoughts are “my opinion”. There is no right or wrong in that, just personal preference.
And my personal preference is for the renders ‘5ar’ has done.
I think they have been well thought out and presented. I also thing his renders represent a very solid platform for this light.
IF they need to be tweaked a bit, no problem. But the ‘platform’ is sound and solid. (to me anyway)
That would definitely look better. Good point.
And in stead of those vertical slots in the head above that maybe 6 flat sections against rolling, would possibly solve my problems with the looks.
I think that is where the head screws on, I would actually like the fins as miller presented them above but extended up a little high into that empty space you pointed out myself before transitioning into the smooth head.
I assume people can read too, so…
But i get the feeling you’re not looking at the design but at the rendering of it.
I just wanted to present alternatives to the head and the ‘pill’ section of 5ar’s rendering.
Sure, he can do the best job rendering designs here obviously.
I can’t do that.
Well, it’s no fun to feel like having to change people’s minds and ‘dissing’ the 5ar design.
I edited mypost a bit, by the way.
Yes, they are nice renders, but the design is ambiguous (i.m. (not so) h.o.)
I would appreciateitif folks would just have a little patience and see if there will actually be something better in stead of just sticking with the first preliminary renderings.
I mean, it has to look good to most of us, otherwise people won’t want to buy it.
And now i’ll stop preaching and will get back with something new later.
I’m with Teacher and Texas_Ace. I really do like the design, can live with the fins as they are already presented, love the accents and anti-roll on the bezel and would just as soon see it stay as it is right now. I would like to see the tactical ring somewhat thicker and contoured, looks almost like it could cut being so thin but it may be a perspective thing with the tube being larger than the eye perceives due to the large diameter of the head.
We’ve been seeing the renders from 5ar enough that they’ve really grown on me. To the point that I’m really pretty convinced it’s just about right as is.
Source a reflector, get solid dimensions, see if 5ar needs to tweak design any to fit the actual in-hand reflector, and move forward.
Some design style is necessary to a degree when the light is parked, but in use the focus will be a mile downrange, behind the light will be dark so it won’t be seen, only felt. If the ergonomics are true, the beam goal is met, then we’ll be golden.
Jerommel, I am not going to re-quote all that has been written
This is nothing personal against you. I am looking at the basic design of 5ar’s renderings…… I like the design, for multiple reasons I have already mentioned.
IF you or anyone else comes up with something I personally like better, so be it. But at this point I am totally sold on the design that the renderings of ‘5ar’ shows. If it gets tweaked a bit no problem, but I am sold on the basic design.
Again, let me be crystal clear; my opinion is based on the design not just the cool renderings.
I also fixed the quote you edited while I was typing.
“So be it” sounds like you (like others) seem reluctant to consider something else, which i find strange and a little frustrating.
This explains my temper in this matter, and / but i apologize for that.
I’ll be back here with something to show to you all.
