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

Super handy though. I love my Zebralight headlamp.

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.

Time for a BLF headlamp?

I would like something like this.

But loose those 2 small ones at the top.

The 2 smaller ones at the bottom should be like the skilhunt H03 with tir lens.

The big in the middle should hold a Convoy C8 like reflector size with a XP-L hi. (Alternative a zommie)

Make the clicky switch in the back of the battery compartment.

And of course add some nice cooling fins to that thing.

Some nice ui and it would be great when fishing or whatever when you are not running.

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

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 like the idea of the Q16, but with 4 xhp70.2 in it instead of 4 xhp35.

I put a xhp70 in a C8 sized OP reflector and really like the beam. It’s a bit throwy, but has great spill.

Puting the 70.2 in the SMO reflector of the Q8 should work well.

Currently you can get 10k lumen from the Q8 with SST40 emitters. We should aim higher than that even though we use the same 4 18650 cells. Maybe go for 5 amp each emitter at 4k lumen. That’s 20 amps at 6 volt (very doable) and 16k lumen.

That’s my kind of light, not 4 xhp35.

My Convoy L6 thread with XHP70.2, Texas Avenger FET driver, Narsil v1.2 ramping firmware (old), lighted side switch and cut down SMO reflector. Lots of amp draws on stock driver as well.

I would be in for sure! As long as we design in good heat management (like the Q8) so we can run on high for a while I would love to have this light. I love the 26,000 lumen from my Acebeam X45vn, but even though it was 15 degrees F. last night I had to shut it down after 2 minutes. That is a little frustrating.

Has BLF ever built a single 26650 light” My all time favorite out with the dog/trail hiking/general use light is my Supbeam K40Mvn. It has a super wide beam that transitions nicely into a very usable spill with a nice MTG2 tint.

I would love to have a nice single 26650 or double 26350 light with a beam profile like the K40m. I would not expect it to give me 3,200 lumen and 90k lux, just have a similar beam and I would be thrilled. Maybe similar in size to the Manker U21.

I am a big fan of single 26650 lights. They are a nice comfortable size to hold and carry in a pocket and the new 5500mA Shockli is getting close to two 18650’s. And when I need even more run time I carry an extra cell in a pocket. That is the great thing about a single cell light; it is so easy to quickly change cells in the field. Even in the dark! That is actually my pet peave with the K40m, battery carriers are so much more difficult to fumble with in the field.

I’ve always preferred 18650’s, but you make a convincing argument.

I’ve read some of the postings from TA about automotive headlight leds. The problem with most aftermarket upgrades in lighting is that they usually are downgrades. Either they emit less light or they don’t collimate the beam into a shape that doesn’t blind oncoming drivers. But some of the newer Philips leds headlight leds have tiny leds that form a pointsource akin to a halogen’s filament. While a separate LED forms the lowbeam and uses a shield to keep from blinding oncoming traffic.

But, in my opinion, all of these lights still could use improvements. Improvements in brightness, cooling, maybe even drivers that allow for smoother transitions from low and and high beams. I think many bulbs use the same capsule but with different bases, so it would be good to have something that would work with many models of cars or trucks. I think a proper set of BLF engineered and tested headlights would be awesome.

I really doubt blf will venture into the car headlight market.

I’ve done successful upgrades on 9007 and H4 lights. I have a thread here on it.

My Convoy L6 thread with XHP70.2, Texas Avenger FET driver, Narsil v1.2 ramping firmware (old), lighted side switch and cut down SMO reflector. Lots of amp draws on stock driver as well.

There is one family of lights that’s really getting on my nerves.
Zebralights.
These have:

  • great quality
  • small size
  • top sustained output for the size
  • top runtime for the size
  • low max output
  • poor ui
  • high price

They are pretty much the only ones in that niche with DQG beating them on size and losing on most other features.
It was said before that Emisar lights are somewhat close. I don’t agree.
D4 is bigger, heavier, floodier yet has much lower sustained output.
D1 is much bigger, heavier and has much lower sustained output.
Some will probably point at FW3A, but it is bigger, floodier and has much lower sustained output too.

I long wondered what would it take to make a good Zebra-beating light and now it seems that all the pieces may be in place.
So I propose the following:

  • 2 emitter choices, XHP35 HI and XHP50.2
  • Schoki’s driver for 2000+ lm with XHP35 and 3500+ with XHP50.2, though that’s just turbo. The latter should easily do 1000+ until battery is empty. The former may be able to do it too.
  • side e-switch
  • 18350/18500/18650 battery tubes

For bonus points (and size reduction) it may be possible to use modern non-dtp MCPCBs and put some driver components on the LED board. Like Zebra, but better. Wink

Overall, such light wouldn’t have low price, no chance of battling Emisar in this regard. But would offer qualities not available anywhere.

I don’t mind the Zebralight UI, especially after using it for a bit. It works, but it’s not nearly as cool or flexible as ramping.

I physically feel the heft and quality of its manufacture, but after owning an Emisar D4, I don’t know if I’d spend the money for a Zebralight today. I seriously doubt it.

I like the multi-thousand lumen capability of the newer lights, but I wonder if it’s really necessary (HERESY!!!). I’m careful with my lights but accidents happen, burns occur and things get melted with the high power. I use the turbo on my D4 only sparingly and mostly for showing off.

Don’t know where I’m going with this but it’s there for anyone’s consideration.

Necessary is in the mind of the beholder. I have an X45vn that makes 26,000 lumen, but depending on the ambient temperature I have 1-3 minutes before I have to cut it way back for fear of melting my fingers. It was necessary one time when my chickens were going nuts in their pen. I quickly grabbed my SD26 and could not see what was causing all the fuss. Then I went and grabbed the X45vn and lit up a 2 acre area like it was high noon. Now I could see one coyote at the far corner of the pen and two more 100 meters back in the pines.

Now most of the time the crazy lumens and lux that we get out of some of our lights is just plain fun. But once in a while they do serve a purpose and get a chance to earn their keep.

Following this direction, I think there’s a better choice than XHP50.2. 3s Samsung LH351D under Carclo triple optics. Shorter and a bit more efficient, especially at high currents. Driver efficiency would be a little lower, so will reduce the LED advantage, though not negate probably. Regardless, the size difference will stay. Turbo output should be a little higher too.

No, I don’t think so.

You just said this 5 days ago, btw.

I’ve done a bit of research on making a 26650 light based on a reflector design and using a side e-switch. There are inherent obstacles to overcome.

If you use a xhp50 or 70 then you either need 26350 cells (which are not common and only 4,000mah worth of energy) or you use a boost driver (which greatly limits your power and UI choices).

Or you go with 3 or 4 single emitters in a reflector with a regular driver, but these light designs are rare.

I built my L5-S and it suits my needs well, but it would be nice to use a single 26650 as it has more capacity (5,000mah) and output potential (20amps).

A new light that just came out is the Sofirn C8F. The latest version uses an side switch, 3 xpl emitters in a triple reflector. The only problem is it’s in s C8 sized body so it uses a 18650 cell.

I literally have not found a good host for a 3 or 4 emitter light with reflector, side switch and 26650 body.

I literally have not found a good host for a 3 or 4 emitter light with reflector, side switch and 26650 body.

I did say the same thing before, but I thought it was more than a few days ago. I was just hoping that someone new might see it and run with the idea.

Is the problem finding the proper sized three or four emitter reflector? How would the U21 work as a host? I have always thought that the U21 would be a good host for a high output emitter because it is such a heavy build and should be able to handle the heat better than some of the thin walled light weight lights like the Olight and Acebeam.

I know almost nothing about what is on the inside of these lights or exactly what is needed to be done to get them to perform the way we want them to, but I know what I would like to see as the result.

Even though I am on the list for the GT, I have found that my larger lights just do not get used very often. For me, lights that are any bigger than the Manker U21, Eagtac MX25L3, Acebeam T21 (with two 18350 cells) and maybe the Q8 are a little too big to just throw in a jacket pocket and go.

The GT is going to be an amazing thrower and I have a couple of dedicated uses for it. What I would really like is a pocketable dedicated thrower and a pocketable general use 26650 light like we are talking about.

I think that the reflector on the Acebeam T21 has about the best diameter to throw ratio out there. If we could use that reflector and a Q8-like battery tube that uses four 18350s like the 1200mAh Aspire cells I would be thrilled. My T21vn throws about 500k lux with two 18350 Aspire cells, but the run time is a little short. Using four 18350 cells would solve that problem and using the pop can style would shorten the light up a bit as well.

WaylonJennings, I to like the idea of a single 26650 light! Thanks for the suggestion….. Thumbs Up

Since the Miller has apparently ‘left the building’, with no real explanation to anyone as far as I have read; has anyone taken the helm of this thread of neat ideas & donations???

Just curious… Because if there is no leadership, how will anything happen as far as a ‘new project’??
