   The light is not the same as a true black body, giving a different appearance to colors than an incandescent bulb. Color rendering quality is specified by the color rendering index (CRI), and as of 2019 is about 80 for many LED bulbs, and over 95 for more expensive high-CRI LED lighting (100 is the ideal value).

3. 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.

   White LEDs quickly matched and overtook the efficacy of standard incandescent lighting systems. In 2002, Lumileds made five-watt LEDs available with luminous efficacy of 18–22 lumens per watt (lm/W). For comparison, a conventional incandescent light bulb of 60–100 watts emits around 15 lm/W, and standard fluorescent lights emit up to 100 lm/W.

   Compared to incandescent bulbs, this is a huge increase in electrical efficiency, and even though LEDs are more expensive to purchase, overall lifetime cost is significantly cheaper than that of incandescent bulbs. [80] The LED chip is encapsulated inside a small, plastic, white mold [81] [82] although sometimes an LED package can incorporate a ...

   Because of this lengthy recycling process, the bulb's life-span is far longer than its incandescent cousin. But while halogens can last three times longer than incandescent bulbs, they are far ...
