Different Kelvins produce different temperatures?

Hei!

I have noticed that my 125W 6500 K CFL gives me more 2-4 t Celsius than 125W 2600 does. Is there any explanation, maybe it is due different minor technical solution in bulb?
 
I would think it was the opposite. The 2700K is in the redder spectrum, more infrared, closer to the warming lights at BurgerKing. At least that is how I've seen it.
 
temps of a cfl are related to how much voltage is used to drive the bulb. The color spectra is dependent on the phosphors used.
different cfls used various ballasts (usually cheap shiits, since they have to have one ballast for every single bulb, as opposed to Tube flouros, which use one ballast for multiple tubes).

So, you are saying it is the ballast that produces the heat, not the Kelvin light range?
 
the ballast controls the voltage is driven through the tubes. Ballasts do generate heat, but the higher the voltage running through the tubes the more heat the tubes will generate. For example BadBoy and Evergreen t5 HOs run hotter and brighter than standard T5 HOs because they use the fullum racehorse ballast, even with the same tubes.

There may be some differences with the different phosphor combos, but thats small.
