Bulb & Socket Guide
PartyLights.com hopes to take the guessing game out of string light and bulb shopping. There are only three bulb sizes that we sell: C7, C9 and Medium. These are the names we use, but these bulb sizes can go by many different names. The images below provide a great visual for bulb size comparison.
A Bulb By Any Other Name...
- C7 Bulbs have a candelabra or E12 base. This size bulb is typically used for chandelier-type fixtures and decorative lighting.
- C9 Bulbs have an intermediate or E17 base. These are historically known as the old Christmas light bulb size.
- Medium Bulbs have a E26 base (E27 in Europe). This is the same size as a standard household bulb.
Besides the C7 or intermediate size references, the base size has the letter-number format. The first letter designates the shape or form of the base. The number represents the width of the base (normally in millimeters). For example, our 11S14 bulb has an E26 base. The "E" refers to the style which is an Edison screw-in, and the 26 means it has a 26 mm base width.
The image below compares our three C7 (E12) base bulb sizes: G30, G40 and G50.
The image below compares our G40 and G50 bulbs in C7 and C9 base sizes.
The image below compares our G50 bulbs in all three base sizes.
The table below lists all of the bulbs sizes available through PartyLights.com. The chart allows you to compare the size and wattage on one page. The sizes listed are the size of the globe of the bulb and does not include the extra height of the socket.
*The bulb wattage is the power that it draws. For LED bulbs, we estimate that the light it emits is about 1 watt per LED. For example, the LED C9 bulb has 5 LEDs, so we estimate it emits about 5 watts.
