Designed for table lamps, this 3-way CFL provides three distinct 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 equivalent to a 30/70/100 watt 3-way incandescent with only 12/19/28 watts of energy used. You'll conserve energy with every use without sacrificing the soft glow associated with incandescent lamps, and this long-life bulb will last up to 8000 hours, more than five times that of standard, 1500-hour incandescent bulbs.Fluorescent Lighting Benefits Fluorescent lamps aren't just for the workshop any more. Fluorescent lighting provides the performance, color and energy-efficiency you want at an affordable price. Screw the 3-Way Compact Fluorescent Bulb into any indoor or outdoor lamp, recessed lighting fixture, or anywhere else you would install an incandescent bulb to start saving energy. One bulb pays for itself in lower electric bills in about five months. Fluorescent bulbs can even be included with your home automation system: Plug the lamp into an ApplianceLinc for instant remote control using any INSTEON or X10 controller.
