    en.wikipedia.org/wiki/Temporal_light_artefacts

    Light source technology: [9] LEDs do not intrinsically produce temporal modulation; they just reproduce the input current waveform very well, and any ripple in the current waveform is reproduced by a light ripple because LEDs have a fast response; therefore compared to conventional lighting technologies (incandescent, fluorescent), for LED ...

    As illustrated by a straight line on the chromaticity diagram, simple two-white blends will have a pink bias, becoming most severe in the middle. A small amount of green light, provided by another LED, could correct the problem. [38] Some products are RGBWW, i.e. RGBW with tunable white. [39] A final class of white LED with mixed light is dim ...

    en.wikipedia.org/wiki/Photometry_(optics)

    The use of the human eye as a detector led to photometric units, weighted by the eye's response characteristic. Study of the chemical effects of ultraviolet radiation led to characterization by the total dose or actinometric units expressed in photons per second. [1] Many different units of measure are used for photometric measurements.
