LED Kelvin/Lumen Level for Full-Sun Plants?

[JaxonPhoto]

Hello, I'm experimenting with tallgrass species native to the great plains in the U.S. that require full to part-sun, but I'm wondering if anyone would know approximately how many kelvins/lumens could support a full-sun plant. Thanks!

Honestly, I was hoping another user who knew more about lighting would swing by and answer this. I don't know much about kelvins and lumens, but a few mid to high wattage daylight spectrum bulbs is usually fine. My best setup for plants has been a large grow light with a normal daylight spectrum bulb in a clamp lamp.
