Does temperature or humidity affect the life of a CFL or LED Bulb? Follow

Some CFLs can be used outside in temperatures down to 10 degrees Fahrenheit and up to 120 degrees Fahrenheit, though when it is very cold they may take longer to reach full brightness. LED bulbs thrive in cold temperatures. There are ENERGY STAR certified bulbs that are weatherproof and can be used outside where exposed to rain, so check for weatherproof models before installing it in your outdoor spot light.
