2. High-CRI LED lighting - Wikipedia

   en.wikipedia.org/wiki/High-CRI_LED_lighting

   CRI is calculated from the differences in the chromaticities of eight CIE standard color samples (CIE 1995) when illuminated by a light source and by a reference illuminant of the same correlated color temperature (CCT), commonly measured in kelvins, indicating the light color produced by a radiating black body at a certain temperature; the smaller the average difference in chromaticities, the ...

3. Parabolic aluminized reflector - Wikipedia

   en.wikipedia.org/wiki/Parabolic_aluminized_reflector

   As with the case of LED MR lamps, LED PAR lamps generally use an array of individual LED elements that are unsuitable for reflector operation. Nevertheless, some degree of beam control can be obtained with aperture or lens, and LED PAR 38 replacements with a 40° spread is common. Models built for stage lighting may use less similar dimensions.

4. Luminous efficacy - Wikipedia

   en.wikipedia.org/wiki/Luminous_efficacy

   Luminous efficacy can be normalized by the maximum possible luminous efficacy to a dimensionless quantity called luminous efficiency.The distinction between efficacy and efficiency is not always carefully maintained in published sources, so it is not uncommon to see "efficiencies" expressed in lumens per watt, or "efficacies" expressed as a percentage.
