All HomeBrite bulbs can be used outdoors, but they’ll need to be protected from direct rain and snow. An enclosed (not air-tight) or covered fixture will be sufficient. HomeBrite bulbs function best with fixtures that offer some ventilation. The only exception to this is the PAR38 HomeBrite bulb. The PAR38 is weather-proof and can be directly exposed to the elements.
All of our HomeBrite bulbs have a minimum starting temperature of -13F (-25C). If the temperature drops below suggested operating temperature, bulbs may have issues powering on.
