To determine a light bulb size, use the full size scale shown (calibrated in eighths). Place edge of the light bulb to be identified on the top end of the scale and measure the approximate diameter by reading the measurement at the opposite edge of the light bulb.
What is the difference between A19 and E26 bulbs?
The term A19 refers to the general size and shape of a light bulb; specifically, the bulb should be roughly pear-shaped, with a length of 100-110 mm and a width of about 60 mm. E26 refers to the lamp base and tells us nothing about the bulbs shape.
What are the 3 types of light bulbs?

Is E26 and E27 the same?
The only difference between the two standards—E26 stands for 26 mm and E27 for 27 mm in diameter—is the voltage (for light bulbs), so a US E26 will fit in a European E27 base and an E27 will fit in an E26 base.
There are four different types of light bulbs available for residential use: incandescent, halogen, fluorescent, and LED. However, lighting has many variables, including brightness, color, temperature, energy efficiency, and dimmability.

What is an E12 bulb?
This type of light bulb base is less than half the size of a Medium/E26 light bulb base and is also known as an E12 base. You typically find light bulbs with an E12 base in chandeliers, small nightlights, and small decorative bulbs.
What is BR30 vs BR40?

How do you match light bulbs?
Voltage, wattage, and base of the lamp are the three primary and most crucial characteristics you must match with the replacement bulbs; bulb shape, type, lumens, color temperature, and life are the secondary characteristics.
Are E12 and E14 bulbs interchangeable?
The E14 will not fit in the smaller candelabra socket (E12 – 12mm), despite the fact that the E14 and E17 are both Intermediate bases, and the E14 will not fit into the larger E17 base.
