is always relative. I knew it would be a challenging mod, especially as I always value clean and reliable work and the host is not as easy to mod as it seems at first glance. (What good is a modded lamp if it suddenly fails in the middle of pure darkness because of sloppy assembly or an LED goes black because of flux residue, for example?)
This is also the reason for the adapters, frames and the many test prints. Better this way than the other way around.
And yet I was not prepared for this. Especially the phase where I tried to convert the whole thing to the 3V driver really tempted me to abandon the whole thing. I probably only went through with it because I had already put so many hours of work into the project…
However, I can confirm that. The thing shreds and has power. Especially when you consider the small head diameter…
Here it is, the perfected now so called LEDLENSER V2 Neo.
With 9 x Luminus SFT-25R G1 BC (highest flux bin at 6500 K) it reaches 6510 lm after 5 sec. at 51000 lx.
(Lowest brightness: 112 lm at 880 lx) - measured in each case with 2 x Samsung INR21700-50S.
With both 21700s, the LEDLENSER V2 Neo weighs 744 g. The thing feels like a single piece of metal anyway. At room temperature, the lamp can run on turbo for about 2 minutes before it gets very warm. The brass pill simply has a high thermal mass which works great in the stainless steel host.
Here are a few beam shots, each on Turbo.

Slightly less than Turbo (50-60%):
Even lower mode (20-30 %):
The LEDLENSER V2 Neo project is now officially complete. The work involved amounts to several dozen hours, not counting the printing time.
It was made by Junghans, one of the largest German manufacturers of the time. The watch shown was manufactured in the 1930s.
The caliber is a Junghans J47b/1 with 15 jewels.
The case is made of 900 silver. The watch is fully functional. I wear it frequently, even in everyday life, with an Albert chain (T-bar chain made of 800 silver) on a vest. It has a rate accuracy of around ± 10 seconds per day.
An inscription for a company anniversary is engraved on the back. The special thing about it is that it is therefore a direct relic of local lignite mining; the companies and mining areas at that time have been history for many decades and can only be found in the history books.
Here are a few pictures (taken in proper warm white environment):
maybe I have a picture of the caliber itself, but I have to look for.
Definitely, although I expected more in terms of brightness, at least when I convert the brightness specifications of the D3AA with SFT-25R to 3x3 LEDs in the V2 Neo. There it should be over 75 kLux with given light flux. But nonetheless, the thing throws out more than enough light for all situations and has also a usable tint.
Speaking of tint: there is virtually no visible tint shift with these SFT-25Rs, as is usually the case with Luminus LEDs.
I was extremely surprised by this, and it has nothing to do with PWM or anything similar because with direct drive from lab power supply this is the same. Presumably Luminus has used a different (more expensive?) phosphor mixture for the highest binned LEDs, possibly because the one normally used saturates quickly and the performance in the specified operating range is lower.
I love my tweed jackets and suits, this pic was not even staged, this was my usual style if I go outside as I took the picture after a walk in the dark
I am loving old clothes and accessories so this light fits great
You added the latest tech to a classic flashlight. Your work with cutting the triple optics, making spacers and all the parts is really well executed and clean.
I like the big light circle that the beam of this flashlight looks like.
I like this too. Ledlenser implemented this “light ring” in their later models (P7R for example), in most cases glowing red which looks pretty cool with the red and black colored tail switch.
Yes, definitely. This build has also taught me a lot, especially when it comes to metalworking, and that will definitely help me for future projects. I’ve already got things planned, made of brass of course.
