Re: having some concernes
The sun gives light at 5150 degrees Kelvin. Have you seen the light that is MH and burns at 5500 K?

The degree Kelvin is not much without the CIR or color rendering index. I recommend 5.3% red light 723.18 nanometers
36.3% blue light 508.7 nanometers
58.3% yellow light 616 nanometers to get 5150 K.
