Although ambient temperature is usually not an issue for LEDs, drivers can fail early if exposed to moisture or condensation and care should be taken to ensure that the driver enclosure is properly sealed. LEDs are also less resistant to damp than other light sources, so close attention should be paid to fixture seals and cable connections. Some condensation or corrosion may eventually form around LEDs due to rain, snow, pressure differences due to elevation changes, and heat buildup or cool down when the LED is turned on and off.
