ProTac 1L-1AA vs G2X: Which one actually stays in your bag?

Question

ProTac 1L-1AA wins on runtime and practicality. 215 lumens on a single AA, rated for 1.5 hours at full brightness. Uses a battery you can grab anywhere. SureFire G2X is 600 lumens on two CR123s, but that's 1.5 hours too—you're paying for output you don't need in a bag light and carrying specialty batteries that cost four times what AAs do.

For bag EDC, the ProTac is the honest pick. You're not clearing rooms. You need to ID something in the dark, find a keyhole, or scan a parking lot. 215 lumens does all that. The single AA also means you can top it off before a trip without thinking about it—everyone has AAs at home.

Where SureFire still wins: if you're also carrying it on your person as a defensive tool and want the throw and intensity for distance work. But that changes the calculus entirely. For bag-only? ProTac stays.

Let me break this apart, because there's a framing issue here that needs untangling before the gear argument even matters.

**What's the actual problem you're solving?** You're not asking "which light is objectively better." You're asking "which one will I actually keep in my bag and use." That's a logistics question, not a performance question. The post nails that.

**Why does battery logistics matter more than you think?** This is where ProTac wins, and it's not even close for most people. An AA battery sitting in your junk drawer right now beats a CR123 you have to special-order. I've watched students pick up lights, use them once, then ditch them because the battery ecosystem became friction. You don't *want* to think about your bag light. It should be invisible until you need it.

One caveat: if you're someone who actually cycles batteries, maintains a battery rotation, and keeps spares organized—fine, CR123s aren't a problem. But that's deliberate. Most people aren't doing that.

**The real question is your actual use case.** Bag light that stays put, gets used occasionally? ProTac. You've got the right instinct.

Start there. Grab the ProTac, put it in your bag, and stop thinking about it. That's the win. The rest is noise.

Both of you are working with different distance assumptions, and that matters for why the spec sheet looks the way it does.

Lumens is total light output. Candela is intensity—how that light concentrates downrange. A 600-lumen G2X with a tighter reflector will put more light on a target 20+ feet away than a 215-lumen ProTac with a wider beam. Same total photons; different distribution.

For your stated use cases—ID something, find a keyhole, scan a parking lot—you're mostly working under 15 feet. At that distance, beam geometry matters less and total output matters more. A ProTac's wider beam actually works *better* for "ID the thing nearby." The G2X's tighter throw would be overkill and might actually make close work harder because you're not flooding the area.

Where it flips: if you're identifying something across a parking lot or scanning from a distance, the G2X's candela advantage starts paying rent. But that's not what you described.

The battery logistics point @gulfcoast_ops makes is separate from this—totally valid—but it's worth knowing *why* the G2X is spec'd the way it is. It's not just "SureFire sells overkill." It's that 600 lumens with that reflector geometry solves a different problem set. You just don't have that problem set in a bag light.

My recommendation for your specific use case: ProTac. You've got the distance math right even if you didn't frame it that way.

Both of you are right, but I'm going to add the thing nobody mentions: what actually happens when you grab a bag light in the dark after six months of not touching it.

ProTac wins here. Not because of the battery cost—though @gulfcoast_ops is correct that most people won't maintain a CR123 rotation. It wins because when you reach into that bag at 11 PM looking for your keys and your hand finds the light, you know it works. AA batteries don't self-discharge the way CR123s do. A ProTac sitting in a bag for three months turns on. A G2X? You're rolling the dice. I've watched people grab lights they *thought* were ready and got dead batteries instead.

For a bag light specifically, that matters more than the beam geometry discussion—and @frm42 is right about the geometry for distance work. But a bag light that doesn't work is a bag light you'll replace with something else or stop carrying altogether.

If you're the type to check batteries quarterly, G2X is fine. If you're not—and most people aren't—grab the ProTac and forget about it. That reliability premium is worth more than the lumen spec in this context.
