2. LED lamp - Wikipedia

   en.wikipedia.org/wiki/LED_lamp

   An LED lamp or LED light [1] is an electric light that produces light using light-emitting diodes (LEDs). LED lamps are significantly more energy-efficient than equivalent incandescent lamps and fluorescent lamps. [2] [3] [4] The most efficient commercially available LED lamps have efficiencies exceeding 200 lumens per watt (lm/W) and convert ...

3. LED filament - Wikipedia

   en.wikipedia.org/wiki/LED_filament

   The power supply in a clear bulb must be very small to fit into the base of the lamp. The large number of LEDs (typically 28 per filament) simplifies the power supply compared to other LED lamps, as the voltage per blue LED is between 2.48 and 3.7 volts DC. Some types may additionally use red LEDs (1.63 V= to 2.03 V=).

4. NEMA wattage label - Wikipedia

   en.wikipedia.org/wiki/NEMA_wattage_label

   NEMA wattage labels are standardized labels defined by the National Electrical Manufacturers Association (NEMA) used on street lighting fixtures to indicate the wattage of the lamp for maintenance purposes. Additionally, various colors are used to identify what type of lamp the fixture uses. A yellow sticker indicates the lamp is a sodium vapor ...

5. SMD LED - Wikipedia

   en.wikipedia.org/wiki/SMD_LED

   SMD LED. The light from white LED lamps and LED strip lights is usually provided by industry standard surface-mounted device LEDs ( SMD LEDs ). [1] Non-SMD types of LED lighting also exist, such as COB (chip on board) and MCOB (multi-COB). Surface-mounted device LED modules are described by the dimensions of the LED package.

6. United States lighting energy policy - Wikipedia

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

   The Light Bulb Freedom of Choice Act, or H.R. 849 (introduced 3/1/2011), also amends provisions from the EISA 2007, but is less restricting than H.R. 91. These provisions concern energy efficiency standards for general service incandescent lamps, rough service lamps, and other designated lamps, as well as incandescent reflector lamps.

7. European Union energy label - Wikipedia

   en.wikipedia.org/wiki/European_Union_energy_label

   Light bulbs From 1 September 2021. Source: Every label of light sources, including light bulbs (halogen, compact fluorescent, etc.) or LED modules/lamps, contains the following information: the energy efficiency category from A to G; the electricity consumption of the lamp in kWh per 1000 hours
