For example, MR16, in the lighting industry, refers to a lamp with a polygonal reflector with a maximum outer diameter of 2 inches.
4. mrmr (multi-facet reflection) refers to multi-facet reflection (lamp cup), and the following numbers indicate the diameter of the lamp cup (unit is 1/8 inch). For example, the diameter of MR16 is 16×1/8=2 inches, which is about 5 mm..
