The E27 base is probably the most widely used. This base was standard for the old incandescent light bulb. Today, you can have LED lamps with the same base. This base is often referred to as Edison base or Edison screw (named after the inventor Thomas Alva Edison) and the lamp type has an "E" for that same reason. The outer diameter of the screw base is 27 mm.
When it comes to lighting solutions, the E27 socket is one of the best known and most widely used
threaded sockets in the world. Whether in living rooms, work environments or outdoor areas - the
socket is extremely versatile and compatible with a wide range of lights. Learn more about the E27
socket and discover the perfect light for your
needs.
What does E27 stand for and where is this type of bulb
used?
The designation E27 describes a screw base with the letter "E" referring to the name of the inventor
Thomas Alva Edison, while the number 27 indicates the diameter of the base in millimetres. The
dimensions of this "Edison thread" are internationally standardised in accordance with IEC 60061:2014
and DIN 40400. E27 bulbs are used in numerous areas due to their versatility and performance and fit
into most lights with screw sockets. Take a look at our lights to find an attractive indoor light with an E27 socket.
The development of the E27 base: from traditional light bulb to LED
The E27 base has a long history and has been a lighting standard since its invention. From classic
light bulbs to halogen and energy-saving lamps to modern LEDs: the base has remained the same, while
the technology has constantly evolved. Today, the bulbs are not only more efficient, but also more
versatile than ever before.
Why is the E27 base so popular?
The popularity of the E27 base is due to its universal applicability. It is used worldwide, is easy to use
and is compatible with a wide range of lights. Whether for decorative purposes, large-area lighting or
energy-efficient solutions - the E27 base has options for all your needs.
Our range of LEDs with E27 base
From classic shapes to candles - finding the right lighting
We offer you a comprehensive range of bulbs with E27 screw bases that are characterised by energy
efficiency, durability and versatile designs. In addition to the classic standard shapes, our range also
includes decorative variants such as the globe, candle, drop and cylinder or the nostalgic-looking E27 vintage series. If you're looking for something special, we have the perfect model for you: with a slim

several times. And of course, our range also includes LED smart bulbs with an E27 base: our
system-compatible lights can be flexibly controlled individually or in groups via app, remote control or
voice command.
Lifespan and brightness of E27 light bulbs
E27 LED bulbs not only offer an impressive service life of up to 25,000 hours, but also boast a high
level of energy efficiency. The luminous flux, which is specified in lumens, varies depending on the model
and intended use. The choice of colour temperature is just as important: warm white light with less than
3,000 Kelvin creates a cosy atmosphere in your rooms, while neutral white (approx. 4,000 Kelvin) or cool
white light tones (over 6,000 Kelvin) are ideal for clear vision and working environments. Use the
intelligent filter function on our website to refine your search results by dimmability, colour temperature
and rated luminous flux value.
Frequently Asked Questions
What are the advantages of E27 LED bulbs?
E27 LED bulbs boast a high level of energy efficiency, an impressive service life and wide range of
applications. However, their greatest advantage lies in their universal compatibility: thanks to the
international standard, there are countless models offering the right solution for every lighting need.
The choice is almost limitless and meets all modern requirements.
Can I also use E27 light bulbs outdoors?
Yes, E27 light bulbs are also suitable for outdoor use. It is important that they are used in a
weatherproof light with an appropriate level of protection so that they are reliably protected from dirt
and dripping and/or splashing water.
Are all E27 LED bulbs dimmable?
No, not all E27 LED bulbs are dimmable. Make sure that the product description and the technical
data sheet clearly specify this feature and ensure your dimmer is compatible with LED bulbs. Dimmable LED bulbs not only enable flexible lighting, but also save energy when dimmed.
What is the difference between E27 and E14?
The difference between the two sockets lies in the diameter of the screw base: while E27 has a
diameter of 27 millimetres, the E14 is significantly smaller at 14 millimetres. E14 is often used for more
delicate lights such as chandeliers or table lamps.
