2. LED lamp - Wikipedia

   en.wikipedia.org/wiki/LED_lamp

   As of 2010 some LED lamps replaced higher wattage bulbs; for example, one manufacturer claimed a 16-watt LED lamp was as bright as a 150 W halogen lamp. [70] A standard general-purpose incandescent bulb emits light at an efficacy of about 14 to 17 lm/W depending on its size and voltage. (Efficacy of incandescent lamps designed for 230 V ...

3. Light-emitting diode - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode

   Efficiency: LEDs emit more lumens per watt than incandescent light bulbs. [171] 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 [172]) and are easily attached to printed circuit boards.

4. High-CRI LED lighting - Wikipedia

   en.wikipedia.org/wiki/High-CRI_LED_lighting

   An incandescent light bulb has a CRI of 100. [1] High-CRI LED lighting is a light-emitting diode (LED) lighting source that offers a high color rendering index (CRI). CRI is a quantitative measure of a light's ability to reproduce the colors of objects faithfully in comparison with an ideal or natural light source.

6. Light-emitting diode physics - Wikipedia

   en.wikipedia.org/wiki/Light-emitting_diode_physics

   Cree's XLamp XM-L LEDs, commercially available in 2011, produce 100 lm/W at their full power of 10 W, and up to 160 lm/W at around 2 W input power. In 2012, Cree announced a white LED giving 254 lm/W, [10] and 303 lm/W in March 2014. [11] Practical general lighting needs high-power LEDs, of one watt or more.

7. 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.
