Difference between E27 and E14 bulbs
The most important 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 or floor lamps. The E14 fitting , on the other hand, has a diameter of 14 millimeters and is mainly used for smaller lamps, such as desk lamps, wall lights, or chandeliers.
Besides the size, there are also differences in application, shape, lamp type, and wattage.In the following table, you will find the most important features clearly compared:
| Type | E27 | E14 |
|---|---|---|
| Fitting size | 27 mm diameter | 14 mm diameter |
| Typical applications | Large fixtures, ceiling lights, table lamps | Chandeliers, desk lamps, wall lights |
| Lamp shape | Often larger, for example pear-shaped (A60) | Mostly smaller, often candle-shaped |
| Lamp types | Incandescent bulbs, LED lamps, energy-saving lamps | Incandescent bulbs, LED lamps, energy-saving lamps |
| Available wattages | Higher wattages (up to approx.100 W) | Lower wattages (up to approx. 40 W) |
E14 Bulbs
The E14 bulb is, so to speak, the little sister of the E27. Here too, the "E" stands for Edison screw, while the number "14" indicates the diameter of 14 millimeters. This smaller fitting is frequently used in compact fixtures and is popular for its elegant design and versatile applications.
E14 bulbs are often used in wall lights, desk lamps, bedside lamps, and chandeliers. They are perfect for atmospheric lighting or spaces where subtle, warm light is desired.
In terms of shape, E14 bulbs are usually smaller and sleeker. The most common variant is the candle-shaped bulb, which is used especially in chandeliers and decorative fixtures.This shape ensures a stylish appearance and soft light distribution.
E14 bulbs generally have a lower wattage, usually up to 40 watts, which fits well with their function as accent or mood lighting. Despite their smaller size, modern E14 LED bulbs are very efficient and are often combined in multiples to generate sufficient brightness.
E14 LED bulbs are available in various color temperatures, from warm white to cool white, and many models are dimmable, allowing you to easily set the desired atmosphere.

E27 bulbs
The E27 bulb is one of the most commonly used fittings for household lighting.The "E" stands for 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 both indoor and outdoor lighting.
Due to their size and power, E27 lamps are frequently used in larger fixtures, such as ceiling lights, floor lamps, table lamps, or outdoor lighting. Thanks to their high light output, they are perfect for general lighting in living spaces, kitchens, or offices where a lot of light is needed.
In terms of shape, E27 lamps are mostly larger and often feature the classic bulb shape (A60). They are also available in globe or spiral shapes for decorative purposes.
E27 lamps can handle higher wattages, often up to 100 W or more, depending on the lamp type (incandescent, energy-saving, or LED lamp).As they offer a strong, bright light, they are ideal for rooms where lighting plays a functional role.
Nowadays, E27 LED lamps are the most popular choice. They combine a high light output with very low energy consumption and last significantly longer than traditional lamps. They are available in various light colors, from warm white to daylight white, so they suit every interior style and application.

Dimmer compatibility
If you are planning to dim 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. Therefore, always check whether the packaging explicitly states that the lamp is dimmable before using it with a dimmer.
In short
Whether you choose the powerful E27 lamp or the elegant E14 lamp – the most important thing is that the fitting matches the type of fixture and the desired lighting atmosphere. E27 lamps offer high brightness and are ideal for general lighting in larger rooms, while E14 lamps provide a warm, decorative atmosphere in smaller fixtures or cozy corners.
Thanks to the many available LED variants, both fittings are energy-efficient, durable, and suitable for almost any application in the home or office.
