- Tumblin's model aims to match a perceived quality known as brightness, measured in brils, so that the real world brightness and display brightness can be equated.

- many of the old units-such as the nox, phot, glim, skot, and scot (identical), as well as the bril and brill (different)—are so antiquated as to be of interest only to the historian.
From Dutch bril, from Middle Dutch beril (“beryl”), from Latin beryllus (“beryl”), from Ancient Greek βήρυλλος (bḗrullos), from Prakrit, from Sanskrit वैडूर्य (vaidurya, “a cat's eye gem; a jewel”), from Dravidian.

From Middle Dutch beril (“beryl”), from Latin beryllus (“beryl”), from Ancient Greek βήρυλλος (bḗrullos), from Prakrit, from Sanskrit वैडूर्य (vaidurya, “a cat's eye gem; a jewel”), from Dravidian. Probably named after the city Velur (modern day Belur) in southern India. The first glasses, manufactured in Italy around 1300, were made of beryl. The meaning "toilet seat" is younger and derived from the similarity in shape. The word forms a doublet with beril (“beryl”).
