Hi!

When it is switched on, it works as expected.

When it is switched off, it blinks every few seconds.

Do you have one of those switches that glows when you turn it off?

No, plain simple switches with no good reason to pass any current when
off.

I have one attached to set a of conventional fluorescent fixtures (one four
tube and one two tube). When the switch is "off" it still passes a tiny
amount of current and this makes for a faint flashing in the two tube
fixture. As far as I can tell this is perfectly safe...it has never caused
any problems for the lamp or myself.

I do, however, have to turn the power off when changing the lamps in the two
tube fixture. Otherwise there is the possibility of getting a small shock.

I noticed the problem when putting the bulb in - it blinked. Of
course, my first reaction was that I had left the switch on but this
was not a likely mistake since the previous incandescent bulb was not
dead.
