He is correct and it is common because what happens is when it cools then heats and cools then heats it creates a vacuum , which sucks the moisture in but doesn't release any do to the water tight seal. Leaving the lens off is not ideal because you will shorten the life of the LED. What type of lamp is it? If the LED itself is sealed from moisture then maybe it would work? You would still have to worry about fixture/ pin corrosion over a long period of time though.
