Default LED lighting for an NPT tank

I posted some questions on the "Lighting" forum and got some very helpful ideass. I'n posting this one here to perhaps get other viewpoints.

In the old days (before LEDs), a lot was written about the "color" of light -Kelvin / color temperature. The consensus was that 5000k - 6500k was the sweet spot. Now nobody seems to talk about it. It would be possible to configure a fixture with "bulbs" of that Kelvin, but there doesn't seem to be any interest in if.

Why? Thank.

Bill

The planted tank LED fixtures I am familiar with all are about 6000K in appearance. I think this is for aesthetics. LED grow lights for other purposes often do not try to mimic the appearance of sunlight, and have a weird purple light (from the concentration of red and blue wavelengths) that is unattractive to most people.

Most of the LED fixtures I've seen don't seem to have any metrics on the packages.
