[PART 1] Official BLF GT Group Buy thread. Group buy officially closed! Lights shipping.

Jerommel, I don’t think there is a person here that does not want this light to “look good”. I think that is what we all want.

I also think that most, if not all of us; want it to be rugged as well as functional also.

As far as “looks” go, that is a subjective choice that differs from person to person… There is no right or wrong, just personal preference.

As far as “rugged” goes, there are some parameters that must be followed if it is to be “rugged”. Angles, creases, ledges (for lack of better words) all add structural strength. All that contributes to it being “rugged”.

And as far as functional…. I think it surely will be.

I completely agree with what Dale says about 5ar’s original design. If it needs some minor tweaking for functional reasons, so be it. But the basic design is there.

Well said here also. I mean honestly, what else is there to say???
:wink:

But, I am an opened minded person. IF anyone can come up with something better, have at it. But as far as “I” am concerned there needs to be some concrete reasoning as to why it is better. Not just some subjective preference. :+1:

English as a second language can be misleading to a Texan who speaks native English slowly. “Then the light can be laid down on a table with the head outside, and still don`t roll away…”

I assumed that “the head outside” meant head off the light. I see now where you might have been thinking that the head is off the table, battery tube on the table, which seems somewhat precarious to me but whatever.

Edit: In my younger years herb mixing with copious amounts of alcohol was the standard. It’s been a couple of decades or more… still understand the concept. :stuck_out_tongue:

Personally I wouldn’t feel very safe having a huge 120mm head hanging off the table…
Don’t want such a heavy flashlight to get knocked off and hit the ground!

Hahahhaahhh :smiley: :wink:

You have to apologise my language skills Dale! Lol
Trying hard to to it right, but som misunderstanding might occur. But I hope we just can laugh at it!! Hehehe :wink:

And about that herb thing…then we “sit at the same table”… UGH! :wink:

Pointing it steady at a target 2k meters down, maybe it would be nice to actually lay it on the table? I wouldn’t mind having this feature on such a heavy flashlight.
But who cares…

Let’s wait on 5ar’s new rendering. :wink:

Use a bag of beans. Bag of rice, anything like that is a great stabilizer for those long range shots, effectively creating a bean bag that cradles the light and holds it stable.

We have the tactical ring at the tail for “hanging the head besides a table” situations right?

Oke, I have run a thermal simulation on the designed head, in order to do that I had to redraw everything. Unfortunately the program crashed and I wasn’t able to save it. :rage: (one of the problems by having it illegal :smiling_imp: )

So I have to redraw it again but will do that tomorrow.
Keep in mind that I’m a still a noob with this program and its the first time I tried a thermal simulation so I cant say how accurate it is.

Here you can see what it means to do a thermal simulation.

Ok

I've added a few finns width of 2.5mm, 3mm spacing distance between the finns, 7 anti roll cutouts, make transition from the widest part to narrow smooth and maybe something else I do not know now.

I do not know which version is better but there is no need at this point to think about it because while I do not know the dimensions and shape of the reflector can not tell whether this look to stay because everything depends on the reflector. Small changes in the details affect the overall look, will be smarter when we know the details of the reflector.

Cross section

someone asked comparison BLF GT and C8 so here it is

and one for lovers of pure design without finns and details hahahah

5ar, I am amazed at your talent!! As well as anyone else who can do this stuff.

Thank you for sharing this!!! :+1:

:slight_smile:

Great designs! I like the latest.

Wow!!!

I am in LOVE with these, I do not see how it could look any better myself!

I like the middle one myself but the far right one is something I could see growing on me if that was what everyone else wanted.

From a purely performance point of view the fins around the switch could be cut a little deeper but that would not effect the looks.

From a modders perspective, if the head screws onto the pill section about flush with the emitter shelf it makes it much easier to work on. If the head is one piece and your’e working “in the hole” then things get exponentially more difficult. Granted, this will have a very large opening, it will also be quite deep… the entire soldering iron will virtually be inside the head.

I am old, I wear bifocals, seeing the fine details from further away is not easy. (OK, I’m not THAT old, but still, seeing the fine details or trying to make the bifocals work isn’t easy working inside a head)

A light like the Courui D01, the Solarforce S2200, the Solarforce M8, these have the head unscrew and show the finned pill section with the emitter and mcpcb right there, very easy to modify. In this scenario, a shelf at the top of the head section for the reflector to rest on gives a fixed base to ensure the reflector is stable and centered.

So I’m still with version 0.4.

What program does 5ar use for the models? Solidworks?

Well, I would think people would use a tripod for that instead of putting it on a table…

Most people don’t necessarily have more than one tripod, if the camera is on the tripod…. bag o beans. :wink:

5ar are doing an incredible job!! thumbs up!! :smiley:
But I did a little “cut and paste” for my self here…and I`ve mixed v.0.4 slightly with v.0.5
Cutted the head juuust above strapholder from version 0.4 and pasted it onto version 0.5

Version 0.45 :smiley:

^ What he said!

If it is like in the picture of the C8, this will not be big at all. It is close to the UF1405 that I have. Lets hope it can throw A LOT better, if that is at all possible. :slight_smile: :slight_smile:

I like the last render by him. The one at the end of his post hehe
