In the LED industry PAR is not referring to your golf game, but Parabolic Aluminized Reflector. This is a description of the bulb that goes inside of a PAR can. The can is the container the lighting bulb goes into. The number next to the term PAR measures the diameter of the bulb. In order to determine what the diameter is, we would divide the PAR digits by 8.

So if you had a PAR64 you would have a bulb with a diameter of 8". If you had a PAR56 you have a bulb with a 7" diameter. If you had a PAR46 you would have a 5&3/4" diameter bulb.

It is important to know the diameter when you are ordering a replacement for your bulb. We hope that this information makes it easy to determine what bulb to order. But if you have any more questions please feel free to call us at 877-632-6935.
