LED lights are being used where ever possible to lower the cost of lighting as well as improve the quality of the light. Transmitting a near white light, LED's have been used from billboards to art galleries. They use a fraction of the electricity that regular incandescent lights use and last much longer. Regular incandescent bulbs only last through about 1000 hours of use where LED bulbs can last over 60,000 hours.
This PAR 20 light bulb operates on a mere 2.5 watts and provides 80 lumens. It fits in a standard light socket and is rated for 120 volts. It has a spotlight design so the light emitted is more focused and directional. It has a 2.5-inch diameter spread so it will fit in small track light fixtures, reading lights, and ceiling fans.
