WebMar 10, 2024 · The risk of trusting LED brightness numbers is that even in the studies mentioned above, the quantification of the HK effect is a highly subjective practice. Choosing to multiply the ANSI brightness value by 2.4 as opposed to 1.3 to obtain the LED brightness can be completely arbitrary and not necessarily accurate.

The scale used to indicate magnitude originates in the Hellenistic practice of dividing stars visible to the naked eye into six magnitudes. The brightest stars in the night sky were said to be of first magnitude (m = 1), whereas the faintest were of sixth magnitude (m = 6), which is the limit of human visual perception (without the aid of a telescope). Each grade of magnitude was considered twice the brightness of the following grade (a logarithmic scale), although that ratio was subjecti…
