Key metrics used when discussing optics:


Full Width Half Maximum; the solid angle at which the light reaches half of its maximum intensity


How much light passes through the optic.


How directive the optic is.

Higher Cd/lm = narrower beam

Distribution Type, such as Type I, Type II, Type III, Type IV and Type V
