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. Common Applications: table lamps; chandeliers; lanterns; wall sconces. 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 sconces, 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.
