I've been debating between 2 bulbs at my hyrdro store 1 has

6000k color temp and 80,000 lumens

Other has 110000 lumens and a 4200k temp if I remember right (was 4000 or 4200)

Is color temp more important or the lumens both are 1000w mh bulbs. The one with the 6000k color is $30 more. Worth it to get that color spectrum or go with the cheaper with more
Lumens?

temp is more important.. generally speaking if you are just starting a grow the 6000k spectrum light is what you want if your going into flower you want a light with a spectrum between 200-300
those are the different spectrums of light plants use and it is because the 6000k spectrum bulbs are more blue/white light and give off the same light as is more usual in the long summer days and begining of veg, when the lights change for flowering since the sun moves to the other side of the equator the light spectrum slightly changes and this is promoted indoors with the usually hps lights are flowering spectrum or ~2500k.
generally speaking 3000k-5000k just a general range is useless for plants because they cant absorb that wavelength, give u a hint its why plants are green!
