2. 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 ...

3. LED tube - Wikipedia

   en.wikipedia.org/wiki/LED_tube

   LED tubes are available with colour temperatures comparable to those of other lighting technologies. However, colder colour temperatures are more favourable in case of the LED technology. The warmer is the light achieved by the LED technology, the more are the benefits characteristic to the technology sacrificed (luminous power, for example).

4. LED filament - Wikipedia

   en.wikipedia.org/wiki/LED_filament

   A 230-volt LED filament light bulb, with a B22 base. The filaments are visible as the four yellow vertical lines. A LED filament light bulb is a LED lamp which is designed to resemble a traditional incandescent light bulb with visible filaments for aesthetic and light distribution purposes, but with the high efficiency of light-emitting diodes (LEDs).

5. Lighting - Wikipedia

   en.wikipedia.org/wiki/Lighting

   The introduction of LED lighting has greatly improved this by approx. 90% when compared to a halogen downlight or spotlight. LED lamps or bulbs are now available to retro fit in place of high energy consumption lamps. Uplighting is less common, often used to bounce indirect light off the ceiling and back down. It is commonly used in lighting ...

6. Wedge base - Wikipedia

   en.wikipedia.org/wiki/Wedge_base

   In Europe, bulbs using wedge base connectors are often referred to by the designations the World Forum for Harmonization of Vehicle Regulations has assigned to them, like P27/7W for W2.5x16q when used as a combined 27 and 7 watt light bulb intended for position, brake and turn lights in vehicles. LED bulbs are also made that will retrofit ...

7. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   Efficiency: LEDs emit more lumens per watt than incandescent light bulbs. [63] The efficiency of LED lighting fixtures is not affected by shape and size, unlike fluorescent light bulbs or tubes. Size: LEDs can be very small (smaller than 2 mm 2 [64]) and are easily attached to printed circuit boards.
