The first thing to understand is what the numbers 30 and 40 refer to. These two numbers refer to the bulb size in 1/8-inch increments. So, a BR30 is 30/8 inches while the BR40 is 40/8 inches. Or to put it more simply, the BR30 bulb is about 3.75-inches wide while a BR40 bulb is about 5-inches wide.
What is the difference between BR20 and BR30?
What is the difference between br20 and br30? 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. Click to see full answer.
What is the difference between br40 and R40?
While R40 sounds similar to BR40, they are very different in design and application. The biggest difference between R, BR, and PAR flood light bulbs is the reflector which is the part of the bulb that reflects and distributes the light emitted.
Can I use BR30 instead of R30?
So, a BR30 is 30/8 inches, or three and 3/4 inches. An MR11 is 11/8 inches. So, you can swap out a PAR30 for an R30 or a BR30 – they are all the same size. Then Does BR30 fit E26? The BR30 is for an E26 light socket, while the A19 is for an A19 socket. The E26 is a smaller / thinner socket and is a lot less common than the A19.
Is br40 same as PAR38?
Is BR40 same as PAR38? PAR38 will fit – the number denotes eighths of inches wide, so PAR38= 38/8″ width, or 4 3/4″w. A BR40 is 40/8″ inch wide, or 5″ wide. About the same size and will fit in the same fixtures. What is difference between BR and PAR light bulbs?
What is the difference between BR30 and BR40 flood light?
