I suspect the lights are pulsating at a rate which you can not detect with your eye. Strobe lights have this effect on photography where you rarely can capture a strobe light illuminated. LED lights are less prone to this and florescent lights are difficult to use in photography. Florescent lights really screw with optical chronographs where the sky screen cannot detect the shadow of the bullet.
I think incandescent bulbs with normal filament work well with photography and video, kind of like the light source grandpa used to use while filming with a movie camera (kind where film had to be developed). My family used an 8 mm (IIRC) movie camera and watched home videos on a reel to reel projector. We used a rail with four bright incandescent bulbs which put off a lot of heat to clearly film indoors.
