    TemperatureTypical Sources

    1000K Candles, oil lamps
    2000K Very early sunrise; low effect tungsten lamps
    2500K Household light bulbs
    3000K Studio lights, photo floods
    4000K Clear flashbulbs
    5000K Typical daylight; electronic flash
    5500K The sun at noon
    6000K Bright sunshine with clear sky
    7000K Slightly overcast sky
    8000K Hazy sky
    9000K Open shade on clear day
    10,000K Heavily overcast sky

    The daylight balanced fluorescent bulbs I just bought are 5500K The Xenon flash tube in the strobe lists at 6500 (or 6490, depending on where I look)

    How can flash ever balance with daylight, except under ideal conditions?

    And why do the charts list flash at 5000K not 6500K?

    No idea, my Nikon SB-800 flash is definitely cooler than 5000K though. I'd put the number between 5200K and 5500K myself. Mind you when taking photos outdoors a 1000K either way still blends in nicely.

    Try taking some shots and see if you can notice a colour cast on your subject, or the background on a nice day.
