Incandescent lamps can't emit UVB radiation, as the filament temperature is too low and it radiates mostly in the infrared and only 5% in the visible light.
Even if the filament is overdriven (As in halogen lamps), still a very pity amount of UVB radiation is radiated.
This is also the reason why blacklight incandescent lamps, don't cause any fluorescence in glowing objects at all (Even if the filament is overdriven in order to increase it UV output).
To get sufficient UV radiation from all wavelength from the lamp, the filament should be heated to the ideal blackbody temperature of 5500degK which is the same temperature of the sun surface.
Neither material can be remain in solid state at such temperatures.
In The LED Museum site , there is a summary of an incandescent blacklight lamp, and you can easily see that the tested lamp don't cause any glowing on fluorescent object.
Spectra of the tested lamp are also included.

Yes, I see lots of package labels on incandescent neodymium bulbs for reptile use that say they emit UV radiation, but it's just not possible. There may be a teeny weeny bit but negligible. Poor reptile wants some UV light and its not getting it.
