Tips:

Reflective bulbs are divided into R type and PAR type. R (Reflector) type usually adopts inner wall coating. The full name of PAR is Parabolic Aluminised Reflector. In addition, AR and MR are common in reflective bulbs, namely Aluminium Reflector and Multiface Reflector.

We usually see MR11, MR16, PAR20, PAR30, PAR38, PAR56, PAR62 etc. The numbers behind represent the diameter of the light source, in units of 1/8 inch. Therefore, the diameter of MR16 is 16*1/8=2 inches ≈ 51mm, so there are also manufacturers who express MR16 light source: QR-CBC51. Other analogies.



The caliber of par38=38×1/8=4.75 inches
