What white balance setting would be used for the relative new LED lights. They are becoming much more used but there is no listing for these. Thanks, John
They are available in so many different color temperatures, giving you a single value would not be helpful.
Relying on the Kelvin temperature is not very accurate, unless you are using the very best LED lights MADE for video, cinematography, and photography.
The $5.00 pack of 60W equivalent lamp bulbs you get at WalMart or Home Depot or Lowe's is likely to be 2700K or 5000K NOMINAL color temperature, but will be missing many parts of the full spectrum. Furthermore, it will probably flicker, requiring a shutter speed longer than the power line frequency (60Hz in the USA).
When shopping for lamps (formal term for "light bulb"), remember these things:
Color Temperature (Noon daylight on a cloudless day is 5500K to 5600K. Household incandescents are around 2750K. Quartz halogen stage lights are 3200K. Cool White fluorescents are 4100K to 4200K but low CRI.)
Color Rendering Index or CRI (A value of 100 is the sun at sea level on a cloudless day — the higher the better for all other light sources. 95 is generally a high quality LED source. Less than 90 is missing (muting) some colors rather noticeably. 80 is really not suitable for photography.)
There are other measurements of spectral output for LED lamps that provide a much finer idea of the spectral uniformity of their output.
To arrive at a reasonably close white balance, I would simply use a custom white balance tool such as a Delta-1 18% gray card (quick, cheap, close to accurate), or an ExpoDisc (expensive, more accurate), or a One Shot Digital Calibration Target (moderately expensive, reasonably accurate), or a ColorChecker Passport (expensive, requires post-processing in Lightroom, EXTREMELY accurate). B&H and Adorama have them, along with many other devices made for custom/preset/manual white balance.
