Elliptical beam
Side Emitting
Key metrics used when discussing optics:
FWHM：
Full Width Half Maximum; the solid angle at which the light reaches half of its maximum intensity
Efficiency:
How much light passes through the optic.
Cd/lm：
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
Benefits of using standard optics:
