2. Luminous efficacy - Wikipedia

   en.wikipedia.org/wiki/Luminous_efficacy

   Artificial light sources are usually evaluated in terms of luminous efficacy of the source, also sometimes called wall-plug efficacy. This is the ratio between the total luminous flux emitted by a device and the total amount of input power (electrical, etc.) it consumes.

3. LED lamp - Wikipedia

   en.wikipedia.org/wiki/LED_lamp

   A 230-volt LED filament lamp, with an E27 base. The filaments are visible as the eight yellow vertical lines. An assortment of LED lamps commercially available in 2010: floodlight fixtures (left), reading light (center), household lamps (center right and bottom), and low-power accent light (right) applications An 80W Chips on board (COB) LED module from an industrial light luminaire, thermally ...

4. Energy saving lamp - Wikipedia

   en.wikipedia.org/wiki/Energy_saving_lamp

   Energy saving lamp. Energy saving lamps are sources of artificial light that employ advanced technology to reduce the amount of electricity used to generate light, relative to traditional filament-burning light bulbs. Examples of energy saving lamps include: Fluorescent lamps; i.e. regular and compact; LED lamp; a Light-emitting electrochemical ...

5. United States lighting energy policy - Wikipedia

   en.wikipedia.org/wiki/United_States_lighting...

   The Energy Policy Act of 2005 (Pub.L. 109-58) provided an energy-efficient commercial building tax reduction program for lighting systems that exceed code lighting. Based on estimates by the U.S. Department of Energy (DOE), lighting represents 40% of the electrical consumption in a commercial building, through the improvement of these systems ...

6. Cove lighting - Wikipedia

   en.wikipedia.org/wiki/Cove_lighting

   Cove lighting is usually installed with LED strips, which have energy-efficiency benefits. They are mounted on an aluminium profile for optimum heat dissipation, with prismatic covers. With a dimming controller (either analog 1..10V controls or digital, DALI based), the cove lighting can be dimmed. A wide range of LEDs are available, from warm ...

7. Sustainable lighting - Wikipedia

   en.wikipedia.org/wiki/Sustainable_lighting

   This approach also augments artificial light efficiency. Energy efficient lighting is not simply finding the most light for the least wattage or the longest lasting light bulb. Proper sizing of the light to the needs of the location and the tasks that will be performed, called task lighting, is an energy saving strategy." [3]
