The Westinghouse 15-Watt (90-Watt) PAR38 LED Flood Outdoor Wet Location Light Bulb with Medium Base can reduce energy and operating costs up to 83 percent compared to a standard incandescent bulb with the same light brightness. This LED saves about $205* in energy costs over the lifetime of the bulb compared to an incandescent bulb. Lasts over 22 years and costs about $1.80 a year to operate, versus a 90-Watt incandescent bulb, which costs about $11 a year to operate and lasts less than 2 years.
