If the driver is decent, yes.

Now this is the key point. To my knowledge there is no AA/14500 headlamp on the market with an efficient driver for li-ion.
This thing I got from Amazon years ago. Like $19(?) with the battery, cable and charger! All the batteries tested above their rating. I bought 3 more after I saw how nifty the first one was.
More Flood than a mule. Perfect for arms length work.
Naturally itâs no longer available.
All the Best,

Skilhunt H150?
2 Thanks
It is well regulated, but not efficient.
2 Thanks
Have you measured efficiency?
The H150 can produce 230lm for one hour with a 800mah 3.6V battery based on: Skilhunt H150 519A Review â Dual-Fuel Excellence â Grizzly's Reviews
That is equal to an efficiency of 80lm/W
However, the 519a 4500K can produce 230lm with an efficiency of over 120lm/W based on:
https://www.reddit.com/r/flashlight/comments/scntbw/nichia_519a_light_output_compared_with_other/
That means that the H150 is only 67% efficient. Which is typical for linear drivers at low currents.
An efficient buck driver can be 90-95% efficient.

nah, thatâs just suggestions, its 2 different setupsâŚ
What do you mean?
Itâs quite clearly a linear driver for Li-ion.

I have been using the Fenix HM50R for over 6 years and I love it.
I bought it because it had a great mode spacing with really good runtimes, especially on the 30 lumen mode which is perfect for messing around at a campsite. I also love the ability to use multiple fuel sources (either a 16340 or CR123A primary). Lastly, I really appreciate the long press to turn the light on. That really decreases the likelihood of the headlamp turning on in a pack while hiking.
Years later, Iâm still super pleased with it. It is the only headlight I have used in that time. The only two things I am beginning not to care for are:
- The USB charging port and rubber cover. While I was originally a fan, I think I now prefer removing the battery to charge and having one less point of entry for water/dirt in the body of the light.
- The cool CCT of the emitter.
Just this week I have considered getting an Acebeam H16. It has almost everything I love about the Fenix but with a neutral white, high CRI emitter as an option and no charging port in the body. The runtimes are not quite as impressive, but itâs a 14500/AA instead of 16340/CR123 so I guess that is expected. However, I carry a 14500/AA light in my pocket daily and if my EDC light and my headlamp used the same fuel, then it would also help streamline things when going away for a weekend. I could take an extra 14500 with full charge plus a couple of lithium primaries and power both lights for a substantial time.
Someone talk me out of it.

Its AA battery type(Alkaline/NiMH Battery) only?
Misleading information from Acebeam :
âCompatible with one AA Alkaline or NiMH rechargeable battery, wide range of Voltage design: 0.9V~4.2Vâ
It ships with a 14500, but can also use different chemistry AAs. From the Acebeam website:
That quote you found is indeed a bit ambiguous.
Look like it can use double fuel too , but again, no stabilization for li-ion ;))
Iâm still in between a casual user and an emergent enthusiast, so forgive the question if it is dumb.
By âno stabilizationâ are you just referring to the unregulated output on the 14500âs? Is there a reason to expect NiMH AAâs to do better? I probably need to pick up some eneloops at some point anyways.
I donât need the high outputs, and can always switch over to running NiMH cells if the performance is better and the driver can regulate the output better.
As you can see , yes. At this point H150 is more advanced.
I just received my Sofirn HS10, with LH351D 4000K. $9.15 USD (at the recent Chinese New Year sale).
Holy smokes, is that a good deal. I didnât need another âLâ headlamp. I already have 3 to choose from. But this HS10 is a great value.
This is definitely a flood lamp. The TIR doesnât really throw that far. Which is fine as I consider most headlamp use for near-field tasks anyway.
The LH351D in the HS10 was noted as being a bit greenish at 4000K and 5000K, but mine looks fine as-is on a white-wall test. A bit creamy warm amber. But yes, next to a 519A 4000K, I can see a tinge of green. Itâs nominal and inconsequential. No visible PWM. Iâm glad I went with it. 4000K is a real sweet spot CCT for me. Not sure about the CRI rating but it certainly looks good. Colors seem to have a nice, natural representation.
I have a ZL SC64c LE with LH351D 4000k, and the CCT looks very closely matched.
I just wish Sofirn had made the tube just a little bit wider and longer for 18350 capacity. Because it wouldnât feel like a notable size change, while opening up greater maximum mAh. Plus, you could use 16340 cells with a spacer to prevent rattle.
One key gripe is that the battery state LED (red) inside the switch is too large and bright. Completely unnecessary. They couldâve reduced it by 50% and it wouldnât diminish functionality. Itâs just so distracting.
Yes, a nice little light. I am just not a fan of the 16340 cells. Too little capacity and they havenât developed them much. Still stuck in that 700 mAh range.

TBF, Iâve seen them as high as 900 mAh for RCR. And Olight sells CR123A 1600mAh.
Main reason I am looking forward to the new Wurkkos headlamp they keep teasing but never showing⌠Will gift my HS10 to friends/family at that point, probably.
Better formfactor for EDC (slimmer â better pocketable) and way more capacity.
