Zebralight has some models, that bring 500ish lumens from Eneloop: SC5w, SC5c. Sc5w says 3 min@550 lumens, then stepdown to 407 lumens, total of 30 min runtime.
I am tempted to get one of these though the price is steep.
That Sc5W is very tempting but that price is a little steep. Still, amazing they can get those lumens from one AA.
Ended up ordering the P20. Never had a Nichia before and specs say 5000K so I may like it hopefully.
Utorch UT01 is 800 lumens with a 14500 cell.
I have several, they are excellent!
Nice light but the UT01 doesn't really look like a pen light.
Well, don't forget you can hold it like a pen ;)
I could, I should, but I can't 
Sofirn SF13? 2×AA.
I got a couple to burn off an assload of AAs. Once my TK4A is done with them (and hopefully before any cells start taking a dump inside it), I’ll pull them and “pair” the cells to go into the ’13 (and oddballs go into my SP10). Once I pretty much get a 1-mode light (ie, all modes are about the same measly brightness), then the cells take turns going onto Bobofett II in nightlight-mode until even that doesn’t light up.
But, with new alkaleaks, and especially eneloops, the ’13 is nice’n’bright.
Any smaller light with high output is going to get hot fast, that said Olight isx in my pocket and any one of many 18650 lights when I need big output for more than a minute or two.
Ordered two SF13's on Sep-9 but still not here yet. Specs show 420lms which seems bright enough for that type of light. I got many lonely AA eneloops waiting to be used.
I heard the acebeam pt10 gets real hot. Did not arrive at my door yet, but for the money, I'm thinking sofirn's SF02 may be the best all around penlight for the money. I really like my thorfire pf04 but many have said Sofirns SF02 is brighter and for just $9.00 it may be my number one Christmas gift choice for friends and family.
Yeah, with new cells it’s pretty bright. Burns down alkies nicely, ’til it’s essentially a 1-mode light, then starts acting weird (flickering, slow-blink, etc.) which means it’s about time for real to ditch the cells. Then into Bobofett II they go.
I’m too busy burning down those alkies to try eneloops or the like.
Anyway, you should be happy with ’em. I am.
I still have a boatload of slightly used costco kirkland AA"s so I'll let the sf13 abuse them all before replacing them with my shiny new eneloops.
I just bought a 2xAAA coast P4 and am also waiting for the 2xAAA led lenser i4 to get in stock soon.
As a general rule I don’t gift lithium lights, usually for the “normal” user its alkalines, and then none have much of a heat issue.
Title says 20 lumens. Must be a very focused 20 lumens as the reviews are positive.
Okay, not quite a penlight but is technically half of one. The Utorch UT01 puts out 800 lumen with a 14500 Li-Ion and 400+ from a AA.
Its steps are programmable, quality is good and it’s offered in both CW and NW tints. I have several and the quality is very good
Yeah, when you’re lucky…
