Here we'll provide you with our super informative Guide to Globe Light Terminology!
Below we show you the differences between E12 and E17 bulb bases, G30, G40 and G50 bulb sizes, and C7 and C9 string light strands.
G30, G40, E12 & E17: What do they mean?
In the lighting industry, bulb shapes and sizes are classified with a letter and numbering code system. This is what the terms "G40" and the like are referencing. The "G" refers to the shape of the bulb: Globe. The "40" refers to the size of the bulb, which in this case would be approximately 40 mm or 1.5 inches.
G50, G40 and G30 bulbs all come in C7 base size.
G50 & G40 come in both C7 & C9 base sizes.
S14, G50 & A15 all come in E26 / E27 base sizes
Base sizes (E12, E17 & E26)
Once you know the measurement of your bulb, you need to be aware that there are also different sized bases, which is the portion of the bulb that screws into the fixture. The most common of these are the E12 and E17 bases. The "E" stands for the Edison screw base. G30, G40 and G50 bulbs all come in E12 bases. Both the G40 and G50 bulbs are also available with an E17 base.
E26 vs. E27
A lot of our commercial strands use bulbs with an E26 / E27 base. The term E26 is used mostly in the USA, E27 in the UK. Bulbs with an E26 or E27 base vary just by 1 mm and are interchangeable. E26 bases may look familiar as they are the standard household light bulb base size. Knowing the base size of a bulb is imperative because the base of your bulb determines the size of the socket you're going to use and vice versa.
