I'm trying to create flicker on a fluorescent fixture in a hospital. Normally I would dim down on the unit or change the voltage to create the desired effect, but there is no drop down ceiling and I can't get access to the ballast without pulling the entire fixture down, which might not be possible.
Has anyone used anything to flicker a fluorescent by where the bulb connects with the fixture?
My other option is to find a bad bulb which probably won't be a problem at this location, but I'm not confident that it will look right without testing it.
All the best,
