What is difference between R40 and br40 light bulbs?
Reflector (R) or Bulged Reflector (BR) 40 bulbs have a reflective coating on the inside of the bulb that directs light forward. Like all light bulbs, the 40 value represents the diameter of the bulb in 1⁄8 of an inch. Therefore, a R40 is 5 inches in diameter. See full answer. In this manner, what is a br40 bulb?
What is the difference between br40 and R40?
