> I was having troubles keeping the regular fluorescent bulbs lit because the humid air would corrode the 2-prong ends.

A little silicone grease on the pins does wonders.
Just look for “Synthetic” Grease. Make sure the label says Dielectric or non-conductive. A 3 oz. tube is about $5 and will last forever.

Too late. I've already switched every fluorescent to LED. And got rid of all those heavy ballasts and glass tubes. Not a problem since. I like the light they put out better than the fluorescents.

Most of the fixtures are up high in the rafters of the barns and sheds and hard to get to easily.

Too many other chores to do on the farm besides greasing light fixtures.

Thanks anyway.

That IS a good preventive measure. I would not use it with incandescent bulbs that can get REALLY hot, however.

I get the 8 oz. brake grease version and use it for all sorts of things. Mechanical and electrical things, I mean. :-)

It’s even food grade (incidental contact) and Kosher!!!
