Lumintop GT nano on the way

Other Types of Lights Keychain / Pocket Flashlights
415

I ordered 2 of these from Neals. This is one cool little light, an excellent companion to my i1R 2 EOS, and GT Micro.

This is probably a limited run, expenses are the same as with a larger light. I think it’s really great that Lumintop is willing to produce these niche lights for those of us who enjoy this hobby.

Anyway, I said I’d buy 2 way back when, and I did it. This will be fun for meteor shower photography (to light up things like the owl who sits on my roof), checking the back 40 for prowlers of the furry kind, taking out the garbage, and whatever else tickles my fancy.

Anyone know where Neal ships from? Is he in China?

416

Yep, China.

Folomov had this problem with the 18650S. Their solution was to recommend a low discharge cell :partying_face: . The lights sold nontheless.

I hope this can be fixed.

418

why couldnt they ask for our feedback if we want other battery type or just change LED so that 10440 will work, i dont get it? why release a version not many want buy and later they want make a blf version ? i cant understand their decisions…… the light got alot of interest and it said 10440 tube now that the light is finished etc it says the led would fry using that emitter? eh ok…. :frowning:

419

No!

420

With a 10440 this light needs a thermal stepdown, does the nano have one?

421

I put a CSLNM1.TG in my GT Micro with an efest 14500 and it’s been fine. Have used it quite a bit on turbo.

422

led dont go blue? weird if a 14500 can run longer but 10440 for lumintop it went blue…

423

Gt micro has a lot more thermal mass.

424

exact
blue is due to heat often

had a C8 with AL MCPCB
went blue at 3A

changed to copper and its good now at 6A

425

ah that would explain it…

426

If the led is mounted well, even in a small host like the nano it should not turn instantly blue, maybe after a while but that is what thermal protection is about, which is part of Narsil/Anduril.

Maybe Lumintop should re-do their 10440 test. Or just get us a 10440 tube separately.

427

If this light will be limited to the 10180, how about adding an option for the CULMM1.tg?

Here is a little video featuring the ......

Lumintop GT Nano.... with some "handling" and a few beamshots near the end of the video.

With thanks to the BiliBili video network and the poster Flashlight player.

I found this video also in a foreign language and has some beam shots at the end

430

I really want one of these lights but I really want a 10440 tube.

Can’t someone that talks to lumintop convince them to produce a 10440 tube separately for those of us who are willing to take the risk if it kills the emitter.

431

it sounds unlikely they will make tubes if it means using 10440 will fry the led…

Some new pictures for the Lumintop GT3 .... (link to original post on Baidu)

The essence

1. Alternative carrying method: 1 and 2 .

2. Beamshots: 1 and 2 . (no data as to output level ... assume highest ?)

3. Video preview with closeups and beamshots ...... @ 1:30.......

With a thankyou to the BiliBili video network and the poster Flashlight player (3) as well as the Baidu FC and the poster "_ 541" (1 + 2).

Thanks,

Martin

PS> I am wondering how am I to know if these links even are used or basically somehow contributing ? (i.e. I am missing a sort of "like" button ? )

433

I just don’t understand why they don’t use a DTP MCPCB. No 10440 would kill the emitter if they did.

434

The GT3 reminds me of the Hakelite MT03. The only issue with that light is Narsil only regulates downward but doesnt know how to regulate up. After minutes of use, the output drops down to 200-300 lumens and stays there. I hope this one has a buck driver to set it apart from the MT03 and to make the light practical.
