  3. 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.

  4. Power factor - Wikipedia

    en.wikipedia.org/wiki/Power_factor

    The presence of reactive power causes the real power to be less than the apparent power, and so, the electric load has a power factor of less than 1. A negative power factor (0 to −1) can result from returning active power to the source, such as in the case of a building fitted with solar panels when surplus power is fed back into the supply.

  7. Light-emitting diode - Wikipedia

    en.wikipedia.org/wiki/Light-emitting_diode

    High-power LEDs (HP-LEDs) or high-output LEDs (HO-LEDs) can be driven at currents from hundreds of mA to more than an ampere, compared with the tens of mA for other LEDs. Some can emit over a thousand lumens. [50] [51] LED power densities up to 300 W/cm 2 have been achieved. Since overheating is destructive, the HP-LEDs must be mounted on a ...

  8. Haitz's law - Wikipedia

    en.wikipedia.org/wiki/Haitz's_law

    It claims that every decade, the cost per lumen (unit of useful light emitted) falls by a factor of 10, and the amount of light generated per LED package increases by a factor of 20, for a given wavelength (color) of light. It is considered the LED counterpart to Moore's law, which states that the number of transistors in a given integrated ...
