ProTac 1L-1AA vs G2X: which one stays in your bag

gulfcoast_ops makes the restockability case well, but there's a measurement issue underneath that shifts the actual tradeoff.

The ProTac 1L-1AA is 280 lumens at a stated 4500K CCT. The G2X runs 600 lumens but spec'd at 6500K—that's a significant color temperature delta. In a bag-light scenario where you're working at distance in dark conditions, that matters for perceived brightness and object recognition.

Here's the geometry: at 280 lumens spread across a warmer beam, you're getting better color rendering on what you actually see, but less perceived throw. At 600 lumens from a cooler source, you get farther reach and that blue-white perception of "brightness," but color fidelity drops. If you're navigating a parking garage (gulfcoast's example), the G2X's cooler output actually helps you resolve pavement texture and obstacles faster because your scotopic vision is more sensitive to that wavelength range in low light.

Battery availability is a real factor, agreed. But it's not the only one. The question isn't just "which light works"—it's "which light lets you see what you need to see, with the battery logistics that fit your actual carry pattern."

If you're in a warm-light ecosystem elsewhere (headlamp, work light) and want consistency, the ProTac. If you're solving a pure "see farther in dark" problem with whatever batteries you find convenient, the G2X's output and color temp do more work for a bag light. My recommendation for your specific use case depends on which problem you're actually solving.

Let me break this apart, because the framing here misses something important.

**What's the actual problem you're solving?** A bag light isn't about maximizing runtime or lumens—it's about having *something* that works when you need it. The OP's battery-logistics argument is solid, but it assumes you're actually going to carry spares. Most people don't.

**Here's what moves the needle:** The ProTac 1L-1AA wins on availability because you can borrow an AA anywhere. Gas station, pharmacy, someone's remote control. CR123s? You're hunting. That matters more in real-world use than the spec sheet does.

**But there's a secondary issue the original post glides over.** Runtime on a bag light is almost irrelevant. You're not running it for 2.5 hours straight. You're using it for 30 seconds to find something, or 5 minutes to navigate a parking garage. The battery will outlast your actual need. What you actually care about is: does it click on reliably, does it throw enough light to work, and can you replace the battery without a scavenger hunt.

If you're already carrying AA batteries elsewhere (which most people should be), the ProTac wins on logistics and restockability. If you're not carrying spares of *anything*, then this decision doesn't matter—any light beats no light, and you've got bigger problems to solve first.

What's your actual carry pattern? Are you maintaining a battery ecosystem or just grabbing whatever fits?

Both of you are making good points, but I'm going to be honest: this whole thread assumes you're optimizing for something that doesn't matter in my house.

I've got flashlights in three places—kitchen drawer, garage shelf, and the nightstand. Not in a bag. Not on my belt. Sitting still where I can actually find them when the power goes out or one of the kids does something at 11 p.m. that requires light.

For that use case, the color temperature argument dissolves. I'm not navigating a parking garage. I'm looking for my kid's toy that rolled under the couch, or checking the breaker box, or seeing if the basement flooded. Thirty seconds of light, maybe two minutes if something's actually wrong. The ProTac's runtime is *more* than enough. The G2X's throw is wasted inside 2,000 square feet.

Here's what actually matters to me: Can my wife grab it, click it on with one hand while holding a kid, and it just *works*? Does the battery situation mean I'm not scrambling to find replacements when I need it? Will it survive being dropped or left in a junk drawer for six months?

The ProTac wins on all three. Single AA means I've got spares everywhere—half my kids' toys run on them. Wife can operate it without thinking about it. No learning curve.

If you're actually carrying a bag light as part of a system, yeah, optimize for the second-order stuff. But most people reading this aren't. They need a light that sits in a drawer and works when grabbed in a panic.

Just get the smaller one.
