White daylight for macro algae ?

[PolypPocket]

I’m looking for a light for my 6 gallon pico tank that will primarily have macroalgea and Xenia. I’ve been reading up on lighting and supposedly need a 10,000 k color temp but only like 15 watts?!?? (I am soooo not knowledgeable about the specs on lighting).
I can’t find anything like that. Could I get some recommendations please? I’m looking for something that isn’t too blue, and maybe has some reddish pinkish tones, and isn’t too strong for such a small tank (please don’t make fun of me for not being able to describe this lol).
I really appreciate any advice

Right now I have the 9 watt version of this and it’s definitely not strong enough, it barely lights up the cube: https://a.co/d/0dDGYsBH

Nothing is in it yet except live rock and whatever came on it, plus a single red macroalgae I bought so I have a little time to find something. It’s a new tank. And of course less expensive is better but am open to all suggestions.

I had a jbj nano glow that worked great for chaeto.

I used a plant grow light on my 10 gallon macro algae tank for 2 years, it was all red light and it grew well. I now use a jebao 60 watt light that was on special at the time, its a more bluish whitish light.

Not implying it is not useable.
6500k LEDs have a tendency to look yellow/ green overall though.
Many rgb based freshwater lights actually have a base k temp around 10000k and don't have a " yellowing" issue.
Finding one with royal blue and 660nm red is a plus.

OK finding a RGB light that includes 660nm leds and having higher power than usual is a bit challenging atm.
Anyways this is an option. Note the base K temp and that it has plenty of power
At 50 cri it is not exactly daylight natural though. Low cri but punchy colors are expected with a RGB array.

Downside, not color tunable or dimmable AFAICT.

Consider this just an example:

Its actually probably more unusable than you think being its a magnet mount built for the back of a biocube and actually discontinued. It was a beast on my chaeto fuge though. I didnt have to look at the color so i was unbiased haha.

I definitely don’t want yellow, thanks for the tip!

The image isn’t showing what brand etc, but the chart helps.

What about this?
