Photon setting to best match 20K 400W MH

[chemwiz]

Cruised through the threads and found a bunch of topics on the sunrise/sunset calculations, but none on what some have done to match the Metal Halide lights the Photons replaced.

Hopeing someone has a good starting place for me trying to emulate the 20K spectrum.

Thank you in advance.

I would recommend replacing half the whites with 14K cool white and adding 6-8 royal blues to the white channel to get that color temperature.
