When you are looking for a new lamp, you often come across the terms E27 and E14. These are two of the most commonly used lamp base types, referring to the type of screw thread and the size of the connection. Although both use a screw 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 read about the exact difference between E27 and E14 lamps, what to look out for when choosing the right fitting, and which types of LED lamps are suitable for both connections. This ensures you 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 base. An E27 base has a diameter of 27 millimeters, making it the standard size for larger fixtures such as ceiling lights and floor lamps. The E14 base, on the other hand, has a diameter of 14 millimeters and is mainly used for smaller lamps, such as desk lamps, wall lights, and chandeliers.
In addition to dimensions, there are also differences in application, shape, bulb type, and wattage.The table below clearly displays the key characteristics 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 lights |
| Bulb shape | Often larger, such as pear-shaped (A60) | Usually smaller, often candle-shaped |
| Lamp types | 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 diameter of 14 millimeters. 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 lights, desk lamps, nightlights, and chandeliers. They are perfectly suited for mood lighting or spaces where subtle, warm light is desired.
In terms of shape, E14 bulbs are generally smaller and slimmer. The most common variant is the candle-shaped bulb, which is widely used in chandeliers and decorative fixtures.This shape provides a stylish look 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 highly efficient. They are often used in sets of multiple bulbs, ensuring that together they still 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” to 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 wattage, 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 high illumination is desired.
In terms of shape, E27 bulbs are usually larger and often feature a classic pear shape (A60). In addition, 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, energy-saving, or LED).As a result, they provide powerful and clear light, suitable for spaces where lighting plays a functional role.
Nowadays, E27 LED bulbs are the most popular choice. They combine high light output with low energy consumption and last much longer than traditional bulbs. They are available in various light colors, from warm white to bright daylight, making them suitable for any type of interior or application.

Dimmer compatibility
If you plan on dimming your lights, it is important to know that not all E27 or E14 bulbs are compatible with dimmers, especially when it comes to LED bulbs.Always check if the bulb explicitly states that it is dimmable before using it with a dimmer.
In short,
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 offer 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 virtually any application at home or in the office.
