what does par mean in light bulbs
The below explanation is correct: No, PAR is not referring to the golf game; PAR (Parabolic Aluminized Reflector) is actually the description of the lamp or bulb that goes inside a PAR can. The can is the container where the PAR lamp or bulb goes. The number beside PAR is a measurement that describes the diameter of the PAR lamp or bulb. To figure out the diameter, divide the number next to PAR by eight. For example, if you have a PAR64, divide 64 by 8 and you will have an 8-inch diameter lamp.
