I’m getting conflicting information about which is more useful for weapon lights, 4000k or 5700k. To be honest I barely started understanding candela vs lumens a year ago, so can someone clue me in on the pros and cons of the two Kelvin ratings?

Simply put I would say 6000k is about as close to neutral/white light. The higher the number the more “blue”, the lower the number the more “yellow”.
I would lean toward that being a personal preference, especially with how close I suspect 4000k vs 5700k is.
Let me add that in my personal opinion and based on my personal experiences, I think a slightly yellow light and is better than a blue or slightly blue light. For me, it's easier to see details with a slightly yellow light. Also, the smoke from firing your gun can create a lot of glare with a weapon light if the light color is blueish.Quote:

I have been told (but don't know if it's true) that it's easier for a manufacturer to get a higher lumen number by making the light color more blue (and less yellow). Even if that's true, the higher lumen number is not always better.

Good to know. What about photonic barriers? If we’re talking about candela of 50k+, is one temp more able to push through barriers than another?
Blue light generally scatters more so a lower CCT light should be less attenuated by and have less glare in smoke.Quote:

Exactly. Remember the old aftermarket fog lights on cars? They were amber to cut thru fog and particulates in the air. Whiter light will reflect more and not penetrate to illuminate on the far side.Quote:

That light actually causes some obstruction of stuff at the far end of the hall from your perspective. Having a higher output light will have the power to burn thru that to illuminate the darkness on the other side of that window light.
