Default Is this sufficient lighting for my newly planted tank?

Hey! Thank you for any suggestions or critique given!
So I’ve recently planted my first tank with some eco complete as the substrate and no CO2. All require low to medium light. Its a Marineland 10 gallon aquarium(Bio-Wheel Kit) which uses a led light bar/hood combination(said to produce 6k).
I realized I needed more light and purchased a Marineland hidden light bar which I have attached to the hood. I believe together with the original Led mounted hood it provides 12,500k of white and blue lights.
Is that enough for sufficient plant growth?*

In case needed I have a few bacopa carolianas and Stellata Octopus as the background plants , Alternanthera Reineckii Rosanervig in the midground, and Cryptocoryne Parva*as the foreground. Some Mini Pellia Moss is also attached to some of the hardscape.

Any help is greatly appreciated!

Thanks again!

Welcome to APC!

You are confusing the color of the lighting with the intensity of the lighting. A light that is rated at 6000K has a color that is somewhat like a light with a color temperature of 6000K - which is what a black body at 6000K temperature radiates. Add another 6000K light and you still have 6000K lighting, but more intense. Light intensity as related to plants is measured in PAR (photosynthetically active radiation) units, micromoles of photons per square meter per second, also called PPFD, but usually referred to as PAR. Low light intensity is about 30 to 40 PAR, medium is about 40 to 50 or 60 PAR, and high is more than that. For more information read https://www.plantedtank.net/forums/1...ead-watts.html
