What are the Different Shapes & Sizes of PAR Light Bulbs?

"PAR"  is an acronym for "Parabolic Aluminized Reflector", this refers to the shape and design of the light bulb.The commons sizes of PAR lamps are:

  1. PAR-16 (PAR16) is 16 eighths of an inch in diameter across the face of the bulb, or 2.0" (25.4mm) Maximum Outer Diameter.
  2. PAR-20 (PAR20) is 20 eighths of an inch in diameter or 2.5" (63.5mm) Maximum Outer Diameter.
  3. PAR-30 (PAR30) or 30 eighths of an inch in diameter or 3.75" (95.25mm) Maximum Outer Diameter.
  4. PAR-36 (PAR36) is 36 eighths of an inch in diameter or 4.50" (114.3mm) Maximum Outer Diameter.
  5. PAR-38 (PAR38) is 38 eighths of an inch in diameter or 4.75" (120.65mm) Maximum Outer Diameter.
  6. PAR-46 (PAR46) is 46 eighths of an inch in diameter or 5.75" (146.05mm) Maximum Outer Diameter.

What do PAR and BR and MR stand for?

PAR stands for “parabolic aluminized reflector” and is best used in settings that require a focused, narrow beam of light. Most PARs do not exceed a beam angle of 45 degrees in most cases. BR stands for “bulged reflector” and is considered a wide-angle floodlight often exceeding 100-degree beam angles. MR means “multi-faceted reflector” and the most narrow of the bulb types mostly used as a spotlight.

Size comparison of PAR vs BR floodlights

It’s actually even easier grasp than you might think. The difference between a BR20, BR30, and BR40 is actually the size or diameter of the light bulb. The number represents increments of an 8th of an inch. For example, a BR30 is 30/8ths of an inch or 30 divided by 8 which equals 3.75″ in diameter. The same example applies to a PAR38. Divide 38/8ths of an inch or 38 divided by 8 which equals 4.75″ in diameter. Check out the comparison chart below. Don’t worry… we’re visual learners too.
