if it has electronic ballast inside it may be knackedOne of my Fluorescent tubes has developed a faulty today.
It's starts up straight away and then goes out, it won't stay on.
Any suggestions?
Does the tube glow at either end when it goes out ?Could the ballast be blown by an arc welder striking up?
Replaced six of mine with LED tubes - instant light and no messing about - time will tell!
