Why is there moisture in floodlight?

- Jan 07, 2019-

1: The internal waterproofing is not done well. If the lighting is not completely cooled, there will be a difference in air pressure.

2: The internal waterproofing is done well, and there is no opening cover for the aging test. (Some glues will also release water vapor at high temperatures, and other factors will not have water vapor in the shell to seal the water.)

Lapu floodlight with a waterproof breathable valve can be selected. The breather valve can reduce heat and balance the differential pressure to improve the integrity of the floodlight.
