The latest and most efficient lighting technology. Their service life is remarkable - usually between 20,000 and 50,000 hours. LED lights also achieve high brightness with minimal energy consumption. A 9W LED bulb is equivalent to a 60W halogen lamp.

LED technology
At the core, it is a semiconductor electronic component that has the ability to emit light or infrared and ultraviolet radiation. This makes it different from other diodes. Officially, it is called a light-emitting diode, or LED for short.
Advantages of LED technology
About ten times more efficient than a normal light bulb
More resistant against vibration and shocks
Can change light without filters
Service life several times longer than other lighting sources
Does not contain mercury
Switching it on and off repeatedly has no negative effects on its service life
The diode can be very small and can be fitted anywhere
Socket
The base part of the bulb that connects to the lamp. There are several types of fittings:
27 mm in diameter, this is one of the most common fittings. It’s used by almost every light source with a voltage of 230 V. You can usually find this type in ceiling or wall lighting fixtures or chandeliers.
Has the same screw as E27. They differ only in diameter, which in this case is 14 mm. The operating voltage is 230 V. Commonly used in smaller lamps, spot lights, and candelabra and chandeliers consisting of a large number of light bulbs.
This socket has no screw. Instead, it has two pins with a diameter of 5 mm that you snap into the lamp and twist slightly. Its operating voltage is 230 V and this type is most commonly encountered in ceiling lights, spot lights, or in bathroom and lavatory fixtures.
A threadless socket, it features two pins 4 mm apart that you snap into the lamp. Its operating voltage is 12V. Most commonly found in kitchen counter lighting fixtures, low ceilings, or bars.
Another threadless socket, it features two pins 1 mm in diameter and spaced 5.3 mm apart. The socket is designed for 12V. Mainly used in smaller lamps and spot lights.
A threadless socket similar to GU10. It has two pins that snap into the lamp. This is the smallest size for 230V LED bulbs. Most commonly used in ceiling fixtures, spot lights, or in bathroom and lavatory fixtures.
A threadless socket similar to other GU types. You’ve got two pins 1 mm in diameter and spaced 4 mm apart that you simply snap into the lamp. The pins must be at least 6 mm long.
This type is used in ceiling fixtures, floor lamps, or footings. The distance between the pins is 53 mm.
