Every single bleeding CFL I find is either cool white but 11w or over 20w but warm white.

I already have the HPS and the bloody warm white CFL's. but I'm trying to fill out my HPS with CFL's in the 4 000 - 6 500 Kelvin bracket. So I found a bunch today which aren't marked with their color, but the shopkeeper thinks they're cool, towards green, which I think could mean around 4 000k, so I bought them.

Apparently there is some sort of relationship between Kelvin and Hertz? Can I work anything out from the 50 - 60 Hertz marking I found?
