It might be best to explain this with an example. Lighting terms can be confusing. In this video, David Geldart of Lumicrest Lighting Solutions demystifies the terms "PAR" and "MR" and explains the numbers b Rather than describing a style of lighting or a theory of design, PAR lighting refers to lighting that uses one of the most commonly found and inexpensive theatrical lighting instruments: the PAR, also called a PAR can.
