I think you can light a tank with some quality led bars that aren't too expensive, Quanta Pros come to mind.

Thank you that’s what I was wondering which LED lights are the best for growing coral and why don’t they sell them in a simple light strip?

Well ask 100 people about spectrum and get 100 different answers.
There is growing ..and coloring ..and viewing

That ties into what " color" of a light strip?

Intensity and the total environment is more important than any color of light.

Of course there is a range of " colors" that are better.
Like nobody would use pure green or red leds and get good growth.

Consensus seems to be low red content, high blue content. Add green or white for looks.

"Daylight" bars have a huge market thus are cheap.
Blue centric bars are " small lot" products.
Especially mixed blue or blue/ white bars.

Simple answer to why are they expensive ..because they can sell them for that price.
Capitalism...

Goes for parts as well if you want to build your own

Thinking more about this today and was wondering are you sure your not mistaking the lights color temperature(kelvin) with the lights intensity or "lumens". This would make way more sense to me with what you have said so far in this post.

Just my guess, but I think the OP is still thinking that their two 6500K strips equals a 13000K strip. Seems like they are really running something closer to a MH spectrum’s . But, you may be right that the OP is confusing lumens and kelvin. I think the color looks like it could be 6500K..

Nope don’t think that never did . I was trying to inspire someone to explain the difference in LEDs I think I know what I need for my new tank build thanks

There are many LED light strips on the market is 6500k what you want for you tank? If you put 2 - 6500k strips do you then have 13000k? What about the colored lights is blue really the blue you want for your Reef tank? The fancy Reef lights are way over priced compared to LED light strips you can buy! If you put red green blue purple orange white together do you then have sun light?

So, when you asked about putting two 6500K strips together, you didn't mean it?

In the future, I will treat any questions from you as a joke then. Best of luck.
