E27 Light Bulbs
The E27 light bulb with a thick thread (27 millimeters) is the most common bulb on the European continent. This well-known E27 bulb, which we also call the Edison bulb, has not stood still in its development. The E27 was first produced as an incandescent bulb, later as an energy-saving bulb (CFL) and now as an LED bulb. The old-fashioned filament has made way for more energy-efficient elements such as LEDs. Nowadays, the cozy appearance of this filament is even combined with economical LED technology. We call these products E27 LED filament bulbs. The most recent innovation is that of smart E27 LED bulbs. You can easily control this new generation of lighting with your smartphone or tablet via a Wi-Fi network. Whichever E27 bulb you choose, you don't have to worry about installing it. Every type of E27 lamp uses the same well-known screw thread where you simply have to turn clockwise to install the bulb.

The colour code is a combination of colour rendering (CRI) and light colour (Kelvin). The first number indicates the colour rendering (1 = very poor colour rendering, 9 = maximum colour fastness). The second and third number contains the light colour. Example: the colour code 830 consists of good colour rendering (8) and warm white light (3000K).
Every bulb or fixture has an energy efficiency class A to G. Energy label A is the most efficient and G the least. LED lighting is the most sustainable lighting technique. Even if a LED bulb is rated E or lower, they still save 70% of energy compared to conventional lighting with the same energy label. Why is it the same label then? To motivate LED brands to get even more durable.
