No, it would not. Not necessarily, anyway. Sure, it’s less metal for the body, but a four-cell light can use a buck driver with large components. A single-cell XHP70.2 light must use a boost driver with small, high-performance components. We see an example of this in the new mtnelectronics 17mm boost driver: it costs $25.


Materials + machining + battery carrier construction + shipping. My light (MT07S) uses boost driver, but it’s indeed not space-limited.

You got your point, indeed driver on such lamp must be much more expensive.

But I did 2 calculations:
1. MT07S + MTN boost driver = $70. Remove the stock driver and the differences on materials + machining + battery carrier construction + shipping. Add a headband. A deal as good as the HKL one could be significantly below $70.
2. Host $15 + driver $25 + LED $10 + $2 headband = $52.

They make me believe that there’s a space to offer cheaper single cell 18650 lights. Headlights included.

No, they are entirely different construction. So called “flip-chip”.
Read this, it’s about another LED but the points are the same.

Higher efficiency, more output, less power draw, less heat, better thermal resistance, higher power handling, etc.

I did some more thinking and calculations on the lightweight, cheap, efficient variant that I’d like to see.

Triple Samsung LH351D would offer very good efficiency per dollar. Would be very floody. Which is good for some, but definitely not for all. Another emitter choice would be easy with the standard XP footprint though.

With CRI70 5000k, 1000 lm OTF achievable at about 2.1A. Vf is 2.92 then, slightly too high for a buck driver but not terrible. In lower modes it’s going to be a bit better.
About 150 lm/W at 1000 lm OTF.
At 250 lm OTF it should exceed 200 lm/W.

Shouldn’t cost more than FW3A.

Going with quad (and preferably 22 mm TIR like Manker) would add some cost, weight and size. But would give the same 1000 lm with 2A. Vf drops down to 2.84 for a bit longer regulation, efficiency goes up to about 165 lm/W.
Same 200 lm/W at about 340 lm OTF.

CRI90 5000k causes 17% output and efficiency loss. Warmer is less efficient still.

ADDED:
XHP70.2 P2 would do roughly 175 lm/W at 1000 lm. That’s 2 hours on a single cell. And 200 lm/W at 450 lm. And may exceed 210 lm/W at lower modes.
So it seems better, but costlier. The cost difference may not be very bad with a low-power driver though. Very floody as well and fixing that would be harder than with LH351D.

Seems I don’t have a good day…
I stand corrected, thank you for keeping me straight. That error doesn’t seem to affect the other things that I wrote in that post though.

If you build/design it they will come. Just like the lantern!

I really like headlamps but I just use a head strap and put one of my other lights in it, usually C8 size. That setup works really well.

Maybe something in a small box size type setup, that would be cool maybe.

I am interested in two depending on price can you please put me on the list………. lol Big Smile

I have a headbands with a BLF D80, and a BLF X6 (I think that’s the model) which is nearly always on them. I use it for just about everything like grilling at night, walking the area around my house, camping, hunting, and all kinds of things like that.

Would love a high CRI, ‘floody spot beam’, L or T format 18650 with ramping UI.

An optional remote battery pack which used a dummy 18650 inside the body as the contacts with a wire through the tailcap to a 4P 18650 pack would be awesome.

Since we are just throwing out ideas, I hope we can see a product similar to the Kogalla RA light.

I like the idea of a led light strip that can be be powered by a battery, hopefully a single 18650, because most led strips I came across requires a 12V source.

The 3 main things I like about this product:
1. you can attach the straplight to the backpack strap or sternum strap
2. being able to store the most of weight in your bag (ie battery)
3. the multiple leds can cover a wider area

Some potential improvements:
1. The UI
2. modular?
3. more minimalistic (too many magnets and is bulky)

This could actually be really cool. I’d love something that attaches to my sternum strap or belt properly.

Something like this could be worn on sternum or arm or leg or strapped to a pack or…?

Great idea!

What I’d like to see if someone ever makes one:

- As light as possible. The skilhunt H03 is only 44g for an 18650. By rough surface area comparisons an AA body should be around 30g or so (1oz). With a battery goal would be around 2oz.
- 14500/AA powered
- Focus on very long runtimes for travel, particularly at modest levels like: 1, 30, 50 lumens.
- Not sure best way to do it, but would love to have flood and throw separately. Like an XM-L2 for flood and XP-L HI or XP-G2/G3 for throw.
- Headband should not have the third annoying top piece
- Under $30

BLF Nichia headlamps/multipurpose lights please.

My current caving setup are two h03s mounted to the helmet. One with 219c 4000k 60° optic and the other with xpl-hi 4000k 20° optic. I love both and can even combine them to have a pleasant flood+throw beam with not so distinct tint shift. I think I got lucky with tint lottery. Difference in CRI is evident if one looks closely but I don’t mind.

How about those quad e21s that clemence sells? I’ve read only great things about them. I think he has got a winner in his Armytek C1 Pro mod with a an extra 18650 tube option. Add more output for turbo, better UI, the ability to swap available optics or reflectors and I think this would be a superb light for enthusiasts and non enthusiasts alike. Even those who have no need for headlamps.

Maybe even offer it as a host where blfers can easily put in their preferred emitters, optics and drivers? And a double mount for those needing both flood and throw in one headlamp. I don’t think 2 shorties would be that heavy on the head and heat would be managed better when both are running at the same time.

Good to see a beam addict like me Beer – I already expressed my thoughts for a customizable headlamp here.

The E21A quads, that I bought from Clemence, are doing a great service for me. I modified 3 Skilhunt H03 headlamps with those (2000K, 4000K and 5000K CCT emitters each). They are very floody with the H03 optics, but this makes them an incredibly good reading /close range working/ lights (The 2000K is a whole different story – it is also very useful for amatheur astronomers out in the field, as it only barely harms one’s dark adapted eyesight, while it gives far more visual information, than a single 630nm red LED /also, it peaks around 650nm/).

I’ll plan to make a throwy OP reflector build as well – high CRI throwers are truly spectacular (I really want one or more with an E21A quad).

Easily interchangeable mcpcb/optic would be great… unscrew the bezel to access triple or quad optic and mcpcb.

I refuse to believe I’m an addict. I’d like to believe that I have very sensitive eyes Steve

I also actually like the idea of a customizable multi-emitter hc65 type light. I like the form factor and the switch of the h65. It was actually my go to work headlamp until I swapped a 219c on the h03. Now I barely use it. I just think maybe a more versatile form such as the right angle light with swappable tubes might get more people excited about a blf headlamp. I think it might also be easier to manufacture. Just my thoughts.

Nice to hear you like them. I’m waiting for the tiara and the extra e21a quad that I ordered from him. You got me curious with the 2000k. I never liked red emitters but I might try this sometime.

With the h03, you might also want to try a 20 degree optic (or narrower if you can find one). I measured a few weeks back (using a smartphone) with my h03 equipped with xpl hi 4000K. The 20 degree clear optics setup out throws the stock op setup using the same emitter (~8200cd vs ~6800cd). I also like the beam of the optics better than the reflector, especially when combined with floody light from another source.

Would love to see Convoy/Simon start offering a headlamp or at least a head for the standard S2+ body.

A strong magnetic tail cap on one end.

Would love for it be offered as a host as well and be customizable like the S2+. The head should be able to
utilize commonly available/standard mcpcbs, reflectors, AR glass and standard drivers.

I’d rather give up a sleek head design for the ability to easily take it apart, replace parts & customize it.

BLF members could come up with a nice custom UI for it.

Wouldn’t you guys love to see something like that being offered by Convoy?

I think it would be very popular. I know I would buy several.

Uhh, that is exactly my topic.
Would love to see some serious headlamps with good efficiency. Head with cooling fins, a nice big button that you can feel well with thick gloves. Separate battery pack – like 2*21700 or something beefy. Could be some silicone packaging, so if you but it to your belt, it can flex. And the cable should be a really good one…most of the cables between battery pack and light fail after heavy use…and fast. For me the heads size would not be so critical. But a good quality light with nice beam and feel is great to have.
Would rather take something throwier than super flood..300m at 1800lm for example..
When using my headlamps in extreme cold and snow storm – the 1000lm reflector lights freeze up because they didnt produce enough heat to defrost the lense. The 2700lm triple XML was nice hand warmener at around 1200lm in those conditions but the throw was shit and the battery pack was just huuuuge.

A well build BLF Headlamp would be nice!
A few days ago my first H03 arrived. And it is a sweet light. It is small, very lightweight and the UI is not totally terrible! But if you are used to Narsil it is like you are using a old outdated light. And thats the reason why a new Driver (Lexels) is already here. Now i have to test a few things (resistor value for a few 0603 leds that i want to put in the head behind the TIR) and then i have to get in the ring with the threadlocker.
A new LED is also on the menue. I like the 219 NW for its color but it is missing the output of a XM-L2. I think i will wait for a led with equal flood capability. Equal or better output but in high CRI.

Other than high CRI, there seems to be a lack of consensus, which bodes poorly for a BLF headlamp. We might as well get Wowtac to use a high CRI emitter and call it a day.

The low mode should be lower.

One single headlamp design probably won't be acceptable for (nearly) all of us. We might want to talk about BLF headlamps of different form factors (I would definitely welcome a single 21700 headlamp, and probably a single 18350 one and a single AA as well for people who don't like li ion batteries - and people who want to give customized headlamps as gifts for non flashaholics).

I use a headlamp a lot, and this is my favourite one at the moment:

Not the best looking light in the world..

Good weight distribution with the batteries on the back.
I put in a Nichia 219C CRI90+ 4000K and replaced the reflector with a very wide angle floody TIR, which i frosted myself additionally.
Simple 3 mode Nanjg AK47 driver with 3× 7135, so it’s 3 Watts max power.
Reverse clicky switch (no drain when off).
Obviously this light is for near field / close up work, such as modding flashlights and painting.

The 2× 18650 last very long, and it has a USB charging port.
Due to the low current (max 1050mA) and thus low Vf you have the same output until the batteries are discharged.
But it still gets pretty warm on 3 Watts.
I mostly use it on medium, which is 30-40% or approximately 1 Watt.
The low mode is good for reading a book (if that’s your kind of thing).
The high mode i don’t use often.
In fact, i could live with a single 7135 for a driver, but the low voltage warning of the Nanjg i wouldn’t want to miss.

So, it’s a great light for long modding sessions, soldering, close up hobbying, etc.

…but here (of course Big Smile ) i read ideas for lumen monsters…
But wouldn’t that give you a lot of light in front of your eyes due to dust and water particles in the air?
But i guess you would wear it higher on your forehead, whereas i have mine just above my eyebrows.
Plus mine is a flooder, so it’s useless in the mist / dust / smoke.

Anyway, i think we need different headlamps for different circumstances.
This one here is pretty useless for riding a bike, for example..
But a powerhouse headlamp would be useless for close up work.
Headlamps like the Skilhunt are in between, not really good for either..

21700 sounds like a good idea for a headlamp. Could make it more versatile with batteries. 21700 or 18650 + spacer or 3 aaa’s + holder.
