The PAR stands for Parabolic Aluminized Reflector.
The number 20 indicates the number of 1/8 inch increments of size.
Therefore the diameter of the large end of the bulb is 2-1/2 inches.

What is the definition of PAR in a PAR 20 or PAR 50 light bulb?
PAR is a outside rated light bulb - R is a indoor rated light bulb.PAR30 = outdoor flood bulb (spot light)R30 = indoor flood bulb (recess can) From MBT lighting & Sound. They are a commercial lighting group. I'm not sure about the indoor (R) / outdoor (PAR) differentiation posted above but the number after PAR refers to the diameter of the bulb. PAR30 would have a 3-3/4" diameter. I verified several PAR sizes. 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 PARcan. 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. PAR56 has a 7-inch diameter lamp, and PAR46 has a 5.75-inch diameter lamp, and so on. The diameter of the PAR lamp is useful to know when ordering a replacement lamp."
