Regarding lamp socket of e14 and e27, many people do not know what these numbers and letters specifically refer to, especially in terms of their differences. In fact, most ordinary LED bulbs use E27 large head screw ports, while smaller E14 small head screw ports are less commonly used.

What are the differences between the two? Let's take a look together.

Some light bulb models have screw and snap on lamp holders, while commonly used lamp holders include E27, E14, E26, etc. These belong to screw socket lamp holders. The letter E represents the screw lamp sockets or lamp holder with Edison threads, and the following numbers represent the integer value of the outer diameter of the lamp holder thread, in millimeters. Therefore, E14 represents a screw socket lamp holder with an outer diameter size of 14mm; E27 represents a screw socket with an outer diameter of 27mm.

In fact, there is not much difference between e14 and e27, mainly because their sizes are different. 14 refers to the diameter of the metal screw mouth part being 14mm; And 27 refers to the diameter of the metal screw mouth part being 27mm.

The difference between the two
1. The diameter of the light outlet is different
14 refers to the diameter of the metal screw mouth part being 14mm, and 27 refers to the diameter of the metal screw mouth part being 27mm. The type of light bulb can be determined by the diameter of the lamp mouth.

2. Different usage ranges
Most ordinary LED bulbs have E27 large head screw ports. And smaller E14 small head screw ports are less commonly used. E14 is usually used in large lamps. In addition, E14 small head screw ports are sometimes used for lighting bulbs in refrigerators or small equipment lighting.

3. Different lighting levels
The illumination level of E27 is brighter and covers a wider range, while the illumination level of E14 is lower than E27, and its illumination range is also much smaller than E27.
