3-4k warm
4-5k neutral
5-6k cool
see how some people call 4k warm and some also call 5k neutral :-). They are reading the values down the right side of the chart
I call
3k warm
4k neutral
5k cool
both are right… better to say the K
High CRI does not exist at 6000k in the lights I typically consider buying
few 5000k lights are 90+ CRI
from 4500k on down, I can buy 90+ cri
tint is not K
tint is greenish, yellowish, reddish blueish
tint is not CRI
I care about CRI the most so I dont buy 5k+
I still hate green, yellow, blue tint, and hope for Rosy
I have a Lumintop Copper Tool with Nichia 4500k and 90+ CRI w 80 lumen high. I use it because it shows reds, even though the Nichia is warmer AND less bright than the Tool w XP-G2
6000k and 70CRI w 110 lumen high. I usually use medium or low, so High CRI is even more important to me because I am looking at things at close range and want to see reds better. I dont need max brightness, I need max Red rendering.
I like 4000k better than 6000k when my eyes are adapted to the 3000k Warm White evening lighting in my house, in that scenario I do not need 80 lumens, 20 is usually enough. The Nichia Tool works best in this scenario.
the reverse is true during the day or when in an environment lit by Cool White light, I prefer 6000k when my eyes are adapted to bright sunlight, in that scenario I also need to use the High mode more. This favors the XP-G2 Tool
Imagine you are going to look under the hood of the car during the day, the Nichia Tool on medium will not suffice, it will be dim and orange.
otoh, look under the hood of the car in the dark of night (with your eyes already adapted to darkness), then the Nichia Tool on Medium is perfectly sufficient, and in fact more pleasing than a glaring cool white (looks relatively blueish) XP-G2 on High.
