CFL Lightning Data: 120 V. Light output: 900 lumens. Energy Used: 13 watts. Life: 10,000 hours. To save energy costs, find the bulbs with the light output you need, then choose the one with the lowest watts. 60W = 13W. Lasts up to 9 years (Based on normal household use of 3 hours per day, this bulb lasts up to 9 years). Proper CFL Usage: CFLs are best suited for fixtures that are left on for 15 or more minutes at a time. They last longest in dry fixtures that allow airflow, such as table lamps, wall scones, pendants and covered outdoor locations. Only use specially labeled CFLs with dimmers and three-way fixtures or in areas that are exposed to weather, since standard CFLs are not meant for these applications. For recessed fixtures, covered glass reflector CFLs outperform uncovered twist CFLs by distributing light to task areas more evenly. 13W twist lamp features: Use 79% less energy than 60 watt incandescent bulbs. Last up to 10,000 hours - 10 times longer than 60 watt, 1000 hour incandescent bulb. Contain lower levels of hazardous materials than RoHS standards allow (restriction of Hazardous Substances). Do not use in wet locations. Not recommended with motion detectors or photocontrols. Do not use with dimmers. Do not use on 3-way lamps. Incorrect use may reduce bulb life expectancy. Common Applications: Table lamps. Lanterns. Wall scones. Chandeliers. Lead-free glass. Reduced mercury content. Lead-free PC board wave soldering. Solderless base. The Ecobulb Plus Difference: All components that make up Ecobulb Plus CFLs have been independently tested to reduce/restrict hazardous materials such as cadmium, lead, mercury, hexavalent chromium, PBBs, and PBDEs. The low mercury content is also solid (amalgam) instead of liquid. These bulbs are RoHS compliant (Restriction of Hazardous Substances) which makes them safer and more earth-friendly than standard CFLs. According to Energy Star, qualified CFLs like these Ecobulb Plus brand bulbs should pay for themselves in about 6 months - based on energy savings compared with incandescent bulbs. Less energy used results in fewer greenhouse gas emissions and lessens the rate at which our climate is changing. When you choose a Feit Electric Ecobulb Plus CFL, It's the bright thing to do. Lead-free glass. Reduced mercury content. Lead-free PC board wave soldering. Solderless base. UL listed. Made in China.
