I bought a set of “Vision X Optimus series round 10-watt led lights 20 degrees”. I had moisture/fogging behind the lens of one. Took it back and replaced it to have moisture/fogging again behind the lens. I replaced both of them with the “Rigid Industries Dully Series 15-watt Led”. Today I noticed that both of them have moisture/fogging behind the lens. Anyone else having this issue with the LED lights?
