Default 5300k,6400k,10000k???

This is not a reply on the topic, but on the topic of lighting the Hagen
Aqua Glo tubes say 18000K but they look more in the red range of the
spectrum. Can anyone clarify this for me. Also I've got a 6500K tube
running on the same ballast which gives a sunlight type look to the tank, is
this a good combo for the plants?

55w
that I have is pretty "yellow-white" and I'm looking for some ideas on
whether a 6400, or a 10k light would be more yellow or more white, or just
too much... or could a Dark Blue bulb be good or ok or indifferent...

obviously, i'm new to lights, and the "concept" behind them, but I'm open
and eager to learn...

I think people gives more importance than they should to the temperature ...

the way I see it:

if the CRI is higher than 75 then the temperature of the colour mean
something useful, if not then it's not useful.

one lamp might be on the 20000 kelvin, but with only a great spike in the
blue, and another not so great but still big on the red.
where is the green, yellow ?

My question would be which lamp is best for the PLANTS. The plants are
really the picture you are trying to show... so what will give them the
best growth and brightest colors.

That is what I want to know..

Please yourself. Intensity matters more than color. As long as there's enough
light, what color it is isn't critical.

Most people prefer the 6400K, but lots of people use 5300K and 10000K, too.
Whatever looks best to you will be fine.

I have a 5000K and a 6500K bulb, and the 6500K is 'whiter' than the
5000K (which has more of a yellowish cast). What 'color' is a 10000K
bulb (or 9600K)?

Many TIA!

Generally speaking, the higher the number, the cooler (bluer) the light looks.
10000K is a very "white" looking light. Some people like that cool,
super-bright look, but others complain that it makes reds look pale and
washed-out.

Many thanks for the reply -

Forgot to mention that I also have a Coralife Actinic bulb that came
with the (used) hood I bought a couple years ago. It's labeled as 7100K
(FR40-T12-360-BP), and it was *BLUE*. I don't use it any more because
it was almost like having a blacklite in the tank - very intense blue
cast. Is a 10000K bulb going to be even 'bluer' than the actinic, or is
the actinic a special kind of bulb that is just super blue in color?

The 6500K bulb (nice and white)I have now is nowhere even a tiny bit
close to the color of the 7100K actinic (BLUE), which is why I wonder if
the 'actinic' is a special kind of bulb whose to-the-human-eye color
doesn't match to the kelvin temp scale the way one would expect...

Just showing my ignorance here ...
