Light bringer hasn't done you any service by talking about batteries that LEAK .
cr123's are pretty much considered old tech and very low capacity . any light that used 2cr123's in them were just burning off excessive voltage beyond the 4 volts or so that the flashlight wants .So you giving it like 6.4 volts means it's just cooking away your battery life because you listened to lightbinger . a primary battery that would be used for long term storage of a light in a very hot /cold environment might make use of a lithium primary and decent eveready AA's are readily available as a replacement for a AA alkaline but you already knew that ...alkalines leak/avoid them is all he meant to say . 18650's don't leak he's only talking about alkaline batteries .
I'd ignore cr123's as a noob and only focus on two batteries . 18650's and AA nimh rechargeable eneloops .
Any light that offers 2 cr123's as an option is usually a very old light .18650's replaced all these old dinosaurs .

Thorfire VG10 and VG15 ////advice given above is accurate Sofirn owns it and they are good lights .
Anker bolder LC30 and LC90////// wouldn't buy it ,,it's an Amazon created light just too expensive for what it is ..
Nitecore (more expensive??)..//// too expensive for a noob . If you opt for nitecore you do so out of fear ..it's just a name brand light .Buy one if it's deeply discounted / last years model sold cheap or if you know it's a light you want .. same advice goes for any higher end name brand light .
Dorcy- I cant find many reviews, but price seems decent///junk ... with an every once in a while light that makes people here say .. huh .. just junk ..avoid anything you see in the stores .
Something else??
Headlight:
Petzl (have not looked up price yet, but have seen it recommended) Petzl IMHO is crap and HUGELY overpriced .Sold to suckers and people who think they want to become suckers .. wow what a mess . buy one and lose my respect .
Ozark trail 250 (I know, Walmart sucks) HUGE crap
Ozark trail 300 more crap
nitecore?/// yeah if the price is half off ... Illum.com has a half off nitecore headlamp
Dorcy Pro series 200 (with or without a tripod seem like a cool feature)-cant find many reviews, but price seems decent//// sorry it has no specs .. probably a single mode ? a xpg2 and i'm only guessing since Dorcy doesn't want either of us to know .. //it's junk
Dorcy- other series seem like a good price too////junk ..if it had modes the spacing would suck or it would have low freq. PWM.. just don't do it ..buy what people here tell you to buy and avoid all lights that have ever hit a big box store .
llllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllllll
for a headlamp I'd buy a Boruit D10 and a Skillhunt H03...$12 and $30.
If you need to buy in the states you can buy from illum.com or mountain electronics
for a flashlight I'd suggest a Convoy C8 the new one in matte black or sand . and a S2 convoy.
If you buy from mountain you can rest assured he came from BLF and carries nothing but nice lights . i'd say you could confidently buy almost anything he sells and be happy
