Candela (or lux) is how concentrated the beam is, which some people call the throw. For instance, the old 300 lumen Surefire M300C has roughly the same throw as the new 500 lumen M300C, but the new version has much more spill, so the light isn't as concentrated. The increase in lumens makes up for it, so you don't lose any distance, and gain more illumination in the surrounding areas.

Traditionally the surefire pistol lights like the x300 have always had less lux and more spill than the rifle lights (which makes sense, you generally aren't shooting 100+ yards with a pistol).

As for which to go with, I hate the switching on everything on the market. The streamlight TLR1 in particular is way too easy to activate. I prefer a handheld for this reason, but if I had to use one, I'd go x300.
Follow up on that, compared to your 300 series which I own, what kind of light, throw, beam shape, etc can I expect with the x300 using the Arisaka as a baseline?

I've been kind of laying it on thick about that light but it's my first light and the only thing I am familiar with.

So far the x300 looks like a solid option. I am just wondering compared to the 300 series what kind of light beam and throw and how wide etc will an x300 light be? (just for my personal understanding)
