1. Difference among PAR20 PAR30 PAR 38
What is the difference among PAR20, PAR30 and PAR38?
Before distinguishing, we should know what PAR means. PAR stands for “Parabolic
Aluminum Reflector”. The number after PAR indicates the diameter of the light. PAR20:
the 20 denotes that it is 20 eighths of an inch in diameter, so it should be 20/8 inch, about
64mm. So the PAR30 is about 95mm, PAR38 about 120mm.
As the above, the diameter is the main difference among the 3 LED PAR lights.
With a flat, round lens that like a car headlight, the par lights are in a cylindrical can-
shaped housing. Different sizes of lenses are available that change the diameter of the
cone of light. The par lights used to replace the traditional halogen lamp. They usually
apply to light a large area such as villa, gallery, hotel, meeting room and so on.
