Bulb Shape Guide Bulb Guides

Below are drawings which you can use to help identify the Shape Type of your bulb.  The code has a letter followed by a number.  The letter refers to the Shape Type and the number refers to the diameter of the bulb in eighths of an inch.  The standard household bulb is A-19: the A is the Shape Type and 19 is 19 x 1/8" or 2 3/8" in diameter.  The MR-12 bulb is the MR Shape Type and 12 is 12 x 1/8" or 1 1/2" in diameter. 

The graphics below are meant as a guide and are not to scale.  Please also note that that there are other shapes.  If you don't see yours, please call us at 1-800-231-1782.
