Designed for table lamps, the Sylvania 3-Way Dimmable Twist CFL Medium Base Light Bulb provides three distinct dimmable light levels: low, medium and high, each offering distinctly different lighting options. The lower light level provides ambient lighting for dining or entertaining, the medium setting offers task lighting, while the high setting offers an excellent light level for intensive reading or studying. Designed for 3-way lamps, this compact fluorescent bulb is set for 12/19/28 Watts and emits 600/1200/1800 Lumens, an equivalent amount of lighting as a 30/70/100 watt 3-way incandescent bulb. This long-life bulb will last up to 8000 hours, more than five times that of standard, 1500-hour incandescent bulbs. You'll conserve energy with every use without sacrificing the soft glow associated with incandescent lamps.Fluorescent Lighting Benefits Fluorescent lamps aren't just for the workshop any more.
