    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.

    An important property of light fixtures is the luminous efficacy or wall-plug efficiency, meaning the amount of usable light emanating from the fixture per used energy, usually measured in lumen per watt. A fixture using replaceable light sources can also have its efficiency quoted as the percentage of light passed from the "bulb" to the ...
