Tungsten-halogen lamps generally run at about the same
temperature as plain tungsten. Tungsten enlarging lamps
generally are around K3000. The color temperature of
household tungsten lamps varies with the wattage but is
around K2950 on average. Standard lamps for color
photography are K3200. Photoflood lamps are around 3400 but
get this high temperature because they are run overvoltage
and have very short lives.
It depends a lot on the bulb and it's intended application.
For photography most integrated reflector tungsten halogens,
EXR 300W and EZE 150W as instances, run at 3350K
