Outdoor lighting systems are designed with sealed housings to protect against environmental contaminants. Atmospheric conditions such as temperature shifts and relative humidity present challenges to the reliability of outdoor luminaires. Changes in ambient temperatures can lead to significant pressure differentials. Over time, pressure on the enclosure seals can cause them to fail and allow contamination and/or water to breach the enclosure. This shortens the life of the luminaire by damaging the wiring, leads and other electronics of the power supply driver and the LEDs. The moisture also reduces light efficiency and can cause condensation to form on the lenses and reflectors.
