1AAA headlights have mostly been abandoned to make way for ultralight usb-c rechargeable built in lithium ion battery lights like the Nitecore NU20 Classic and the NU25 UL that can put out 360 to 400 lumens on turbo and last a decently long hike at a modest output. If you want those characteristics in a light with removable regular batteries, I suggest bumping it up to a 1AA light and getting a Fenix HM23 V.2.0 headlight and getting a lithium ion cell to bring the weight down. There is also the brighter Acebeam H16 1AA headlight. RCR123A/16340 lights are also an option like the Sofirn HS10, Fenix HM50R v.2, or the Olight Perun Mini. Those will be between the weigh of 1AAA and 1AA, but give you removable batteries in case you want to bring spare cells for longer trips or don't want to replace the whole light when the internal battery goes bad. Other than the Sofirn, those options are pricy. I'd rather spend $60+ on a 18650 Nitecore HC60 v.2 than one of those lights. The newest version of the HC60 doesn't have a real medium or low setting and can't take 123A lithium primaries for winter or travel. Has more efficient l.e.d.s and comes with a 4 amp battery vs. a 3.4 amp, but you lose solid regulation, several hundred hours runtime on low, and medium is 100 lumens so you get attacked by insects all the time. Medium should be between 25-60 lumens. Low should be 1 to 5 lumens.
Try the Zebralight H53C. It's a 1xAA headlamp with a user-selected L-M-H sequence. Each of the three levels offers two output choices:
- Low / ultra low;
- Medium / Medium Low;
- High / Turbo.
Output levels are easily changed using only the head-mounted power switch.
I cannot speak for the Fenix HL10, but I do have a Manker E02H that I use for close-up work, specifically when connecting the tiny front connector cables on a PC motherboard.
Both lights only take unprotected cells (which is my main downside), but the unprotected 21700 cells that I have bought for the PL47MU (Samsung 40T) will fit and can be charged in any 18650 charger that I have tried them in. Same with the Samsung 25R and Molicel M35A 18650 cells for the DW4.
The PL47MU seems completely out of stock, so perhaps the L70 is another option but I have no experience with this model.
