It varies based on the ballast. Most ballasts nowadays are "power factor corrected" to try and compensate for the bad powerfactor in switching power supplies. The actual power factor of a individual fixture is entirely dependent on the circuit of the ballast, which changes from design to design.

Fluorescent means something is glowing, usually with visible light. Fluorescent means giving off visible (or invisible) radiation as a result of absorbing shorter wavelength radiation.
