Lighting forms a ubiquitous network for deploying digital infrastructure-LED lamps with built-in sensors and transmitters can capture “data in the world” that helps businesses and cities run more efficiently and effectively. Smart LED lamps and fixtures are enabling intelligent environments all over the world. While CFL and halogen lamps won’t disappear overnight, more customers are choosing LED, and not just for energy and maintenance savings. LEDs have come to prominence in the market, and the potential for more is at hand.
Most emit light in a specific direction, versus in all directions, but Current’s traditionally shaped LED bulbs are omnidirectional (designed to emit light all around, like a standard incandescent light bulb). Small LED chips allow for more compact, design-forward fixtures, as well as the illumination in tight areas. Can last up to 25 times longer than incandescent and halogen, and up to three times longer than most CFLs. Can use up to 75 percent less energy than incandescent. 
Also fitting in linear applications, such as under cabinet lighting, where light sources with thin profiles are needed. Virtually all indoor, outdoor and roadway applications where incandescent was traditionally found, especially where lights are left on for extended periods and changing bulbs is not easily done. LEDs are light sources that become illuminated by the movement of electrons through a semiconductor material.
Instant start (halogens do not experience the delayed warm-up associated with CFLs). Many are 10-20 percent more energy efficient than incandescent bulbs. This creates lower energy use for the bulb.ĭisplay lighting where users want to spotlight merchandise or outdoor applications where bright light is needed office lamps. The halogen gas then carries the evaporated tungsten particles back to the filament and re-deposits them. When the bulb is lit, tungsten from the filament is evaporated into the bulb’s gas, providing illumination. Halogen bulbs have a tungsten filament just like incandescent bulbs, but halogen bulbs also are filled with halogen gas. Now that incandescent light bulbs belong to the history books, building owners and city officials must choose between compact fluorescent (CFL), halogen and light-emitting diode (LED) lamps to illuminate built and natural environments.Ĭurrent, looks at each technology and explains why LED is emerging the clear winner in most cases: CFL
