LED light

[Bewarned]

I was under the impression that the number of bands a light is coincides with the number of different bands of light...
but according to a led store on EBay I am wrong....this is what I was told by them because I questioned there light since it only has 7 different bands of light...
this is what I was told the light was

10Bands means Full Spectrum .
610-615nm
620-630nm
650-660nm
440-445nm
460-465nm
730-740nm
3500K-4000K

I just asked them again, they said it is full spectrum 10bands include all wavelength which plants need ,so we call it 10bands or full spectrum .
I just checked that all sellers on ebay call full spectrum light as 10bands, could you please kindly understand us ? this is the rule of this industry .

Can anyone please help me out ...
just trying to learn...

I think you have your terminology mixed up. Each band is a color within the full spectrum.

It is hard to evaluate if the lights are giving out the right spectrums the plant needs unless you have researched what is needed by the plants. The easy way to go is to find the best LED by side by side comparison, look up the spectrums and see how it compares to the lights you are looking at.
