Im setting up a planted sh tank, been doing tons of research on lighting, and Im going to use a special type of LED I found. But wanted to know if I can grow soft corals under a 6500 light?

Thanks

Do you mean a 6500K bulb/color spectrum? If so, yeah it will grow them, but they will be brown under that spectrum.

Thank you, yes I did mean 6500K. Can I grow plants well in a reef tank with a 10000K or 15000K?

Define plants... Do you mean macro algae? Mangrove?

Mangroves, Mermaid Fan, Gracilaria, Ulva, Caulerpa.

Mangroves grow out of the water, only the roots are in the tank and I'd recommend a yellow/white light for the actual tree above the tank. The rest should be fine under reef spectrums. I'd probably lean towards the 10k or a yellow bulb with lots of blue to off set it like a 4 or 6 bulb t5 setup. Have you looked at what other planted tanks (saltwater not fresh) are using?

That is the Sun's spectrum.

No I didn't even think about comparing to FW planted lol. I'm using a 47 Column tank, for this set up. I'm going to use smaller LED bars for the dawn/dusk cycle for the SH, and I'm going to use these LEDs I found from a guy in Sweden for the plants and few corals I want. Trying to stick with as clean and basic look as possible, to include the lighting. I'm wanting to use these LEDs because they are small and sleek. I think Ill use the 6500K and a actinic for some color. How does this sound?

Going to need a lot of blue to off set the yellow...
