What does R30 mean on a light bulb?

Reflector (R) bulbs put approximately double the amount of light (foot-candles) on the front central area as General Service (A) of same wattage. Like all light bulbs, the 30 value represents the diameter of the bulb in 1⁄8 of an inch. Therefore, a R30 is 3.75 inches in diameter.

Is BR30 light bulb same as R30?

The difference is simply the diameter of the bulb. R30 bulbs are the larger of the two bulbs. BR30 bulbs are actually the newer, more energy-efficient version of R20 bulbs and are the same size as R20s. R30 bulbs have a diameter of 3.75 inches, while BR30 bulbs have a diameter of 3.5 inches.

What is the difference between R30 and R40 bulbs?

R30 vs R40 As with all LED flood light bulbs the difference between R30 and R40 is the diameter, which can be measured with the number code by referring to it as 1/8”. Using the R30 bulb as an example, the number 30 would represent 30 eighths of an inch, which would mean that the diameter of the bulb is 3.75”.

The reason for the bulge in incandescent versions of the BR30 lamp is to enable a wide flood beam of 120 degrees or more.

What is an LED reflector bulb?

LED reflector bulbs are lined with a reflective surface to create a wide beam angle. Types of LED reflector lamps include Reflector (R) and Parabolic Reflector (PAR or PR). LED reflectors are available with E14 and E27 bases, and are often used in stage and recessed lighting, security and kitchen lights.

What is the difference between PAR38 and BR30?

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.
