Hello:

Have installed a two bulb linear fluorescent fixture bought from HD as
an overhead shop light.

Have it all wired in now.

Howver, about 50% of the time, turning on the switch does not cause the
lights to light.
But, flicking the switch once or twice always gets them going.
Once on, they are perfect; no flickering.

Wired to a new wall switch I installed for that purpose.
Switch is fine, I believe.

Any thoughts on what might be the problem ?

Thanks,
Bob
