I'd ask why?
There's a particular reason why - the lighting is for a room for use by
disabled people, some of whom have indicated an intolerance of
fluorescent lighting. We're trying to offer an economical alternative.
That is likely caused by flicker. Changing to electronic ballasts sorts
this as they run at a much higher frequency than mains.
Though
http://en.wikipedia.org/wiki/Fluores...licker_Effects
says there's also a perceived flicker effect that affects some people as a
result of the spiked spectral pattern of the light output, even when using
high frequency ballasts.
But changing to LEDs won't necessarily help with that. (And as other people
have said, whether it will help with 100Hz flicker depends on the drivers
(and, as with fluorescent, the phosphor used).)
