No it doesn't work that way. The 3000K rating (K is for Kelvin) is the temperature of the globe and does not change. 3000K globes have a lot of yellow and red light but not much blue.
Natural sunlight has a Kelvin rating between 5500-6500K and has red, yellow, green, blue and ultra violet light in it.
Ultra violet (UV) sterilisers have lots of UV light and a Kelvin rating around 10,000K.
You want globes with a 6500K rating for best results.
