R20 bulbs are a style of flood light bulb with a reflective coating on the inside of the bulb. As with other flood lights, the 20 indicates the bulb’s diameter in 1/8 of an inch. This means any R20 bulb’s diameter is approximately 2.5 inches.

How long is an R20 bulb?

The designation “20” on a light bulb indicates the size of the bulb. Light bulbs are measured in eighths of an inch, so a bulb designated as a size 20 measures 20 eighths of an inch, or 2 1/2 inches, across at the largest point. This means that R20 and PAR20 bulbs are the same size.

What is the difference between BR and R light bulbs?

BR bulbs are descendants of the R-shape bulb and therefore very similar in shape. However, the “Bulged Reflector” bulb (abbreviated as “BR”) includes an extra reflector in the neck of the bulb to better capture and cast light forward which was previously lost in the neck and sides of the standard R bulb.

Is R20 same as PAR20?
