Moisture on 240v Connection

Not on the boat but at home. Got 240v flourescent lights in a damp warm location. They are ip65 rated but still the contacts appear to get condensation on making them "flakey".

 

Is a dab of dielectric grease any good for this application?  Or anything else. Prefer not to use wd40 as it stinks!

Is this inside the IP65 housing? Is there a gap in the housing where air can be exchanged? Could just be moisture from damp air trapped inside? Electrical contact grease won't do any harm. Might do some good.

Yes.  I think the area undergoes a bit of temp swings and the grommets are not 100%.

It may help to increase the ventilation to the housing as when the lights are on the temperature goes up the warm air will evaporate a lot of the moisture, if it is ventilated the warm wet air can be replaced by drier cold air taking the moisture away.

Maybe need a breather pipe to outside the warm wet room.
