Replace your energy-sapping incandescent spotlights with the 120-Volt 36-LED 2.5-Inch Par20 Spotlight Bulb, which has a focused beam well-suited for ceiling lights or garden applications. At only 2.5" in diameter this bulb fits just about everything from small track light fixtures and reading lights to small ceiling cans. The 36 super-bright white LEDs are combined with a real glass lens to put out a beautiful, almost true-white light. The energy-efficient outdoor 120-V olt 36-LED 2.5-Inch Par20 Spotlight Bulb uses about 10 percent of the energy of a standard floodlight. Since it uses LEDs instead of standard filaments, this bulb never gets hot and uses only 3 watts of power. It's safer and more economical than halogen and incandescent bulbs, as well.
