The modern equal are large(ish) 'compact' flourescent that are daylight balanced in thier gas mix.
With them there is no need to filter out the bulk of the lower temperature tungsten emission spectra with the blue filtering to just pass emission of the daylight balanced portion of their spectra.
Then there are also banks of daylight balanced LED's coming to market in the theatrical lighting business. I have not looked to see if they have crossed into the photo lighting spectrum. The LED emisions are very spiky, so colour balance is likely not daylight balanced withthe theatrical LED's yet.
