My understanding, to throw further confusion into the mix.
Those red and blue LEDs are such narrow wavelengths of light they do practically nothing for plant growth and its purely down to the output of the white LEDs. The RGB LEDs are there purely so you can adjust how the light appear to your eyes, and the bulk of the actual light output is from the white LEDs.
Remember that white light is a mixture of wavelengths of light across the whole colour spectrum. Red wavelengths promotes long growth and blue wavelengths promote vegetative bushy growth, so you need both, so look for a light fitting where the white light has wavelength peaks at the red and blue ends of the spectrum. Green light isnt all that important to plant growth.
This is the colour spectrum of fluvals plant light output.
If you are planning on keeping those low demand plants then pretty much any aquarium light fitting will be good. Light fittings intended for higher demand plants tend to just have higher light intensity and be targeted more to those red and blue frequencies.
Sorry if ive added some more confusion into the mix. And its not like im an expert here, just passing on my understanding and will follow along as im interested in what others say too.
