Reference: cutoff

Reference information:
A measure of glare control: the angle at which you can no longer see the lamp (or its image) in a fixture. Cutoff is measured from directly below the fixture; low cutoff mean you cannot see the lamp unless you look directly up into it. Sharp cutoff fixtures provide very precise glare control but may leave the top of the wall in shadow.
