Still some interest in a 3xAA light. It is also interesting because the overhead voltage between a modern low voltage led and 3xNiMh-in-series is close to ideal again for lineair drivers (7135 based) or even FET-drivers: good efficiency and still good runtime in regulation.

I did a test holding a 3xAA carrier with switch (phosfor-bronze springs) against the head of my LuxeonV-modded D4. The Eneloops were not quite full but it gave me a steady 1250 lumen for the 10 seconds that I managed to keep the parts in place in the entrance hole of the sphere.

It would be an ideal high performance light for people who aren’t necessarily flashaholics.

I want the long version of that very light, with the three AAs placed nose-to-tail. I know it would be about 200mm / 8 inches long, but I like long lights :slight_smile:

Of course the various 4xAA lights out there fill that niche as well (D40A, EA41), the merit of this one is that it is exceptionally thin and short.

@Phlogiston: 3xAA in a tube would work just as well (even a bit better because the resistance in between the batteries is virtually zero), that is of course a matter of preference, I like stubby lights, you like long and thin. :slight_smile:

But this one would be less expensive than either of those I imagine.

> Three AAs nose to tail

You can do this by combining tubes from a SK68 clone and a “3W Police” flashlight (see the lego thread)
I’ve still got a Brinkmann 3AA tube light in the “do something with this someday” bin.

Google finds a lot of other 3AA flashlights (limiting search with /Tools/verbatim, and then choosing /Images)

I’d like to see a djozz-inspired 3AA BLF light myself.

Now this is weird. Two emitters, one spot and one flood — and an infrared beam to decide how far away the subject is to balance power to the emitters.

What will they think of next?

(I’m waiting for the flashlight design where you click the button and the light head extends little propellers and flies over to hover and illuminate your target, while you control it from the battery tube)

I don’t know if it has been mentioned before. But I would love to see a BLF head lamp.

I would too if only I’m not allowed to wear a headlamp at the risk of divorce :frowning:

It just might be impossible to make those things look cool. :person_facepalming:

Super handy though. I love my Zebralight headlamp.

Heck yea!! i’ll take 3 or 4 of those 3xAA lights…maybe mor, make great gifts too.

I’m not sure it would be cheap, I can imagine it being 30 dollar, structurally it is not unlike the Q8, 4 high power leds, and a battery tube for 3 cells (bored out for 3 cells with a rotating tailboard, my preference, or with battery carrier). One advantage: with 1A per led a DTP board is not needed.

1+ on the BLF headlamp but I’m guessing that Zebralight headlamp of yours is one of those tiny ones that don’t have big heatsink or cooling fins?
Btw there are plenty of those small ones.
The ones that doesn’t exist (what I know of) is a good big headlamp with a battery compartment at the back.

Mike C was looking for a good headlamp host in This thread.
I been searching too but I just ended up disappointed.

Quote for me in that thread.

Edit: 1+ on djozz 4 emitters 3xAAA light.

You joke, but we are not far from that. Current drone tech is there, just need work on the AI side.

Has BLF ever produced a small 10440 light? I know that I would be interested in a nice little 10440 light with a high cri led with ramping UI.

I like this idea. Is there an advantage to using a battery carrier over a drop in battery tube? I personally favor the simplicity and easier in the field battery swap of the battery tube.

Most people prefer a thicker light than a super long one.
When you need the cells in series, a battery carrier is the simplest and cheapest option compared to having a special rotating PCB and alignment pins.

The other options is to have all the cells in parallel and use a boost driver, but those are harder to make, rarer, and often less efficient than buck or DD.

I’d buy one, maybe even several. They’d make great gifts!

:+1: YES! Me too

Ehm……am I the only one longing and drooling for a BLF Q16 monster output light?
