So a BR30 bulb’s diameter is 30/8 inches, or 3.75 inches (3 ¾”), and a BR40 is 40/8 or 5 inches across the diameter. This is a measurement of the widest part of the bulb, broken down into 8ths of an inch. The bulb code consists of a number after letters R or BR such as 20, 30, 40 etc. The defining feature of BR/R bulbs is that they provide a broad beam of light, which is less concentrated and fills up a larger area with its diffused light effect.įurther, these bulbs are made of more fragile glass and are pretty lightweight. ![]() ![]() So you can see that a BR bulb is much more efficient and brighter than an R bulb with the same rating and wattage.Īpart from this physical change, BR and R bulbs are usually interchangeable, provided they are the same screw type and size. This would unnecessarily light up the area behind the bulb, and a little luminosity was lost, making the bulb inefficient. The R is shaped in a way that doesn’t make use of the light reflected back into the bulb, which would leak as the reflector ended just before the base. A BR bulb is shaped to have an extra bulge at the neck of the bulb to include a reflecting surface area off of which the internal light can bounce back outwards, utilizing the full luminosity of the light! The Difference Between BR and R The name ‘bulged’ comes from a physical feature designed to correct the inefficiency of an R bulb.
