some differences in flashlight use scenarios
close range in full darkness, and indoors:
lower lumens, wider beams, warmer Color temperatures
longer range, and when adapted to cooler ambient light, and outdoors:
higher lumens, narrower beams, cooler color temperature
I carry a floody light for close range that is high CRi and high R9, and less than 5000k. I use less than 100 lumens indoors, and I prioritize High CRI for that. My indoor use targets are usually smaller and more detailed, and their color is more important to me, especially things like food.
and I carry a spotty light for outdoor distance, that is cooler and has less CRI and less R9 and is more than 5000k. I use more than 100 lumens for outdoor distance, and have less of a fixation on accurate color rendering,
because the target is usually larger, and I mostly just want to know if there is a bear there or not. Im less concerned with the color of the bear.
if the use scenario is to spot a bear, brighter spottier and cooler is better
if the use scenario is to prep food at camp, hang out indoors relaxing, less bright, floodier, and warmer is better, for me.
ymmv by use application
Im 65, wear glasses, have cataracts and other vision challenges, but old ladies with blue hair definitely do not look like blond barbies to me
I also dislike green tint, and 5000k+ low CRI lights have more green tint than my sub 5000k High CRI lights.
However I dont notice the green tint of my cooler lights when my brain is white balanced to cooler CCTs durig the day. I notice the green tint of 5000k+ lights more, when I am adapted to the incandescent light in my home at night.
