At first for me it is a difference between "not like at all" and "hate". Only to make this clear. I am not english native speaker. I also own some 4000K lights, and I use them also.
I guess the first point is 4000K depends on the LED, 4000K may be yellowish. The HDS XP-L 4000K is kind of yellowish, also the SS40 that HDS had is a bit more on the yellow side in compare to NB40.
I did long time ago an emitter compare (unfortunately 219B 9080 was not included since it was not even existing in the HDS world). The original posting is in the legendary Hogo "
Low K group buy" (picture is from 2018).
in this picture you see different tints of 4000K lights. Seems I like 4000K more with a higher part of red light in it. The NB40 has this.
Also there are some people that love NB4 (219B 9050 4000K) but I unfortunately do not own a NB4. Therefore I can not judge NB4 vs. NB40.
Also the beam itself is very homogeneous in color. The inner and outer beam is more or less the same. That is somehow interesting for me if I am doing some photography stuff with some spot illumination. Sometimes for such tasks beams with different light colors are a problem. The biggest problem is if you later shift the color calibration. You may know photography is my 2nd hobby.
If the NB27 arrived I hope I will find the time on doing my big 2022 HDS LED color compare. Maybe that helps to understand it more ... ???
