Can I be lazy guys and some one tell me whether both group buys are over, so that I dont have to go back and read through the whole thread? Kinda interested in the light but can’t spend too much money at the moment. Thanks in advance!
The $111 GB is full but the $150 GB is still open.
It should remain open until the lights go on sale.
Posted this a while ago, it is the proto 1 with the shorty tube, the humidity was high and is across water meaning the conditions are real life 
As an aside, the focal length was 35mm on a cropped sensor, close to what the eye sees.
How much better the production model will be is unknown at the moment but high humidity will still be a problem.
Cheers David
I feel your pain, taking Lux readings outside the calculated throw actually goes down as I move further back instead of going up like it should the humidity can be so bad. I usually get the highest readings around 5m, which is much less then should be ideal for a light this size.
I have a water tower I spotted recently that should technically be in range of the gt (about 1 mile) but I kinda doubt that it will reach that far with the humidity and light pollution.
Thank you kind sir!
You are right, I meant the Thrunite TN42vn. 
Quite happy for the larger swath of coverage of the TG! :+1:
The pics into that reflector are almost hypnotic, am i becoming a flas-a-holic ?
I thought a reflector was in a grinding machine before polish, i know a CNC lathe can do a okay surface, but its nothing compared to the surface tolerances i far surpassed on my grinding machine.
setting off on a new batch with the stone fresh sharpened, my grindings was slicker than snot on a door knob.
BUT ! i have no idea if you can grind on ALU as you can on tempered steel or raw steel / stainless, but i figure its just a matter of using the right stone for the job.
Some times i worked on some large axles that had gotten a layer of crome, and that shi, stuff was a pain to work on, i have no idea why they dident get those axles sprayed with some proper steel, figure it was cornor-cutting saving money , which i hate as its so noob and anyone can do it.
And besides a CNC lathe could fab up a new axle much faster than i could redo the tolerances on my grinding machine, especially as this was raw steel axles only needing a few grinds where rubber seals was seating.
Dont get it :person_facepalming: some times its like stupid run things.
Jack, as was said before, this is not an Acebeam topic. This is considered hijacking the thread. You need to create a new topic in the commercial sellers spot here:

Or maybe search for an Acebeam thread at least.
Aluminum is so soft it will just clog up the grinding stone. You need sandpaper style flap discs or rolls and even those wear out quick. Like this.
Please add me to the list as well. Thanks!

Any update on the shorty tube being available for purchase?
Are the springs on the same PCB as the Bat+ contacts? And the bars are on the outer PCB too? That would mean by removing the protection PCB, the battery carryer wouldn’t shrink and it would be verry easy to remove it.
Is it right so?
Sorry I do not understand the abbreviation, my question can you tell me what these batteries type model and manufacturer. ?
I bought them from nkon.nl from the Netherlands, at a good price. https://eu.nkon.nl/rechargeable/18650-size/sanyo-18650ga-button-top.html
@Texas_Ace
Thanks a lot for your detailed answers!
- I thought the chosen XHP35 HI was CW since CW is usually higher output (maybe I'm wrong, I'm not deep in this field)
- Thanks for the advice on the batteries. No worries, I understood the "official" recommendation now ;)
- BTW, I usually use a Neodimiun super strong very "small coin" magnet that has Nickel coating, instead of solder blob. Did you try it?
Thanks a lot once again!
Also thought the emitter would be cool white for the increased throw. Why not offer both, no big deal to build lights with two different emitters.
Two different emitters is a big deal in manufacturing, somewhere in production you have to separate two production runs that even to trained eyes are almost indistinguishable.
Were any of the proposed GT logos mentioned in the OP ever posted publicly? While Lumintop has opted against custom logos, I’d love to have one printed on die cut vinyl for my hard case with permission from the designer(s).
