When you're looking for a new bulb, you'll often come across the terms E27 and E14. These are two of the most commonly used types of lamp fittings, referring to the type of screw thread and the size of the base. Although both use a screw-in fitting, there is a clear difference in size, wattage, and application.
The E27 fitting, also known as the standard fitting, is often used for larger lamps such as ceiling lights and floor lamps. The E14 fitting, on the other hand, is smaller and is widely used in ambient lighting, table lamps, and chandeliers.
In this article, you will learn exactly what the difference is between E27 and E14 bulbs, what to look for when choosing the right fitting, and which types of LED bulbs are suitable for both bases. This way, you'll always make the right choice for your lighting.

Difference between E27 and E14 bulbs
The main difference between E27 and E14 bulbs is the size of the fitting. An E27 fitting has a diameter of 27 millimeters, making it the standard size for larger fixtures, such as ceiling lights and floor lamps. The E14 fitting, on the other hand, has a diameter of 14 millimeters and is primarily used for smaller lamps, such as desk lamps, wall lamps, and chandeliers.
Besides the dimensions, there are also differences in application, shape, bulb type, and wattage.In the table below, you can see the most important features clearly listed side by side:
| E27 | E14 | |
|---|---|---|
| Fitting size | 27 mm diameter | 14 mm diameter |
| Common applications | Large fixtures, ceiling lights, table lamps | Chandeliers, desk lamps, wall lamps |
| Bulb shape | Often larger, such as pear-shaped (A60) | Usually smaller, often candle-shaped |
| Type of bulbs | Incandescent bulbs, LED bulbs, energy-saving bulbs | Incandescent bulbs, LED bulbs, energy-saving bulbs |
| Available wattages | Higher wattages (up to approx.100W) | Lower wattages (up to approx. 40W) |
E14 bulbs
The E14 bulb is the smaller sibling of the E27. Here too, the "E" stands for Edison screw thread, while the number "14" indicates the 14-millimeter diameter. This smaller fitting is widely used in compact fixtures and is popular for its elegant appearance and versatile applications.
E14 bulbs are often used in wall lamps, desk lamps, night lights, and chandeliers. They are perfectly suited for ambient lighting or spaces where subtle, warm light is desired.
In terms of shape, E14 bulbs are usually smaller and slimmer. The most common variant is the candle-shaped bulb, which is widely used in chandeliers and decorative lamps.This shape provides a stylish appearance and a soft light distribution.
E14 bulbs typically have lower wattages, often up to 40 watts, which suits their function as accent or ambient lighting. Despite their smaller size, modern E14 LED bulbs are very efficient. They are often used in sets of multiple bulbs, which together produce sufficient light.
E14 LED bulbs are available in various color temperatures, from warm white to cool white light, and are often dimmable, allowing you to easily create the desired atmosphere.

E27 bulbs
The E27 bulb is one of the most commonly used fittings for household lighting.The "E" refers to the Edison screw thread, and the number "27" indicates the diameter of the fitting in millimeters. With a size of 27 mm, the E27 fitting is one of the largest screw fittings available for indoor and outdoor lighting.
Due to their size and power, E27 bulbs are often used in larger fixtures, such as ceiling lights, floor lamps, table lamps, and outdoor lighting. Thanks to their high light output, they are ideal for general lighting in living rooms, kitchens, or offices where ample light is desired.
In terms of shape, E27 bulbs are typically larger and often have a classic pear shape (A60). Additionally, globe-shaped and spiral bulbs are also available for decorative applications.
E27 bulbs can handle higher wattages, often up to 100 watts or more, depending on the type of bulb (incandescent, CFL, or LED).As a result, they provide powerful and bright light, suitable for spaces where lighting plays a functional role.
Today, E27 LED bulbs are the most popular choice. They combine a high light output with low energy consumption and last much longer than traditional bulbs. They are available in various light colours, from warm white to bright daylight, making them suitable for any type of interior or application.

Compatibility with dimmers
If you plan to dim your lamps, it is important to know that not all E27 or E14 lamps are compatible with dimmers, especially when it comes to LED lamps. Always check if the lamp is specifically listed as dimmable before using it with a dimmer.
In summary
Whether you choose the powerful E27 bulb or the elegant E14 bulb, the most important thing is to match the fitting to the type of fixture and the desired lighting atmosphere. E27 bulbs provide ample light and are perfect for general lighting in larger spaces, while E14 bulbs create a warm, decorative look in smaller lamps or cozy corners.
Thanks to the many available LED variants, both fittings are energy-efficient, durable, and suitable for almost any application at home or in the office.
