Yes some are like that other seem to kind of fade on. I don't see them
nowadays but our studio has quick start electronic ballasts and apart from
blowing one after 10 years they have been fine.

I recently sought opinion on what I should do about the 5 foot 58w T8
magnetic ballast type fitting in my utility room. The problem was that it
was switched by an occupancy switch (PIR), to allow hands free switching
when walking in and out of the room with hands full.

The options were - leave as is (the tube's heaters were being hammered, by
regular starting), change to an LED strip, or change the magnetic ballast
for an electronic one. When it is on, t is not on for long, so no big
advantage for LED. I decided on the latter option (E-Ballast)and managed
to find an electronic ballast for £7.60 delivered and fitted yesterday.

I was half expecting the series connected PIR not to work and having to
modify the light to allow it to charge up, but it worked fine without any
changes. Light comes on instantly, but with a slight strobing, which
clears within seconds.
