Has anyone here ever measured the color temperature in K of the various standard E27 edison base tungsten fixtures?
Color temp. seems to vary quite a bit with wattage (15 vs. 75 or 100 Watts, being warmer with the lower wattage bulbs), but it's difficult to judge by the eye..
Unfortuntely I don't have a color meter handy.. has anyone ever measured?

Greetings,
Marc

1600-2500k for the most part from my meter depending on type and wattage

100W bulbs tend to be fairly consistently around 2800K. I recently measured some 15W candelabra base bulbs in a bar that were around 2200K collectively but individually measured from 1700-something-K to 2700K.
