That wouldn't surprise me. Incandescents emit light by way of what
physicists call "blackbody radiation," which everything in the universe
emits, proportional to its temperature above absolute zero. It is broadband
("white noise") up to a point but does eventually have a low-pass
characteristic. For incandescents, it starts falling off in the infrared,
which is why they look yellowish and they are good sources of heat, but
there is much less energy in the ultraviolet.
Fluorescents work by generating tons of UV and then converting it to visible
