Powersavercfl.com is the premier resource for all of your CFL product needs. Our energy saving Superior Life® CFL bulbs are Energy Star rated and guaranteed for long life. Our lamps utilize Amalgam cold start technology as well as a special coating in the glass in order to maintain lumens over the life of the bulbs. Without the coating the lumens denigrate to around 80% of the design life. With the coating the lumens remain above 90% of their design life. Many of our competitors bulbs are lacking many quality upgrades particularly with their coatings and ballast. All of our lamps are tested, lighted and packaged for maximum performance. We hope you enjoy your time on Powersavercfl.com and our experienced staff is here to assist you.
