I have a couple Preon 4Sevens versions of the O’Pen, one is always on my desk. I gifted a few family with the O’Pen in orange and bronze. Very classy looking penlights.
I have the Olight, 47’s, thorfire and lumintop, all good chices with good output although the first 2 are no longer made. The olight gets extremely hot on high to the point where you have to change modes or turn off. Lumintop has a nice metal clickie.
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.
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.
