Color temp is in degrees Kelvin. 5000-6000 is a bright, daylight white. 2700 is a "warm" incandescent white, ie, yellow, sometimes called "soft white."
good example of the visual difference
The photo lab where I used to work, the lighting was VERY important. You needed consistent, daylight white light everywhere. One time someone ordered new fluorescent bulbs for all the fixtures in the ceiling, and brought in a scissor lift to install them. They "got a deal" on some of the bulbs.
The cheaper bulbs were a different color, much warmer toned. Oh, man, was the owner mad! But the manager said there wasn't money in the budget to replace the incorrect bulbs.
Probably because he was embezzling funds...? Yeah, I've wished I could say that. A lot.
