Flu lamp ballast

Kelly Marie Angel

I was wondering why is it that some of the LED flu lamp replacement tubes say to leave the choke in circuit I don't see what good it does apart from dropping a few volts   also I would think the little voltage Spike at switch off wouldn't be helpful either

    There is a safety reason for doing so. If someone mistakenly puts a standard tube in the fitting, and the tube struck, it would then explode due to the current flow. If the choke is left in circuit, it will limit the current and the worst it can do is stay illuminated.
