I don't know the colour ratio. I think the light manufacturer keeps that to himself.

I do know that my light is 7 band and includes Infra Red and Ultra Violet. The new lights are 14 band and also include the IR and UV. I think they will have a marked difference.

If I could advise you I would say go with my kind of light. But in the end, whoever you buy from, be sure you ask a lot of questions about the company and the product quality.

Take care.
