Bulb Size Reference
Sunlan Lighting Inc. wants you to know that lamp size is determined by the maximum diameter expressed in eighths of an inch (1/8"). For example, an A19 lamp is 19-eighths of an inch or 2 3/8" in diameter. To determine a lamp size, use the full-size scale shown below (calibrated in eighths). Place one edge of the lamp to be identified on the top edge of the scale and measure the approximate diameter by reading the scale at the opposite edge of the lamp. Sizes of the more popular lamp types are indicated on the scale.
Sunlan is always the best! I needed 12 unique bulbs for our new light and didn’t know the size. I received such great help in finding exactly what I needed. Wonderful shop and we are so so happy with our light :)
