A light source is the technical core of every luminaire. It is the component that actually produces light, and the choice of light source affects everything from the atmosphere and functionality of a space to energy costs and how the colours of your walls are perceived. We believe in lighting that stands the test of time, both in design and performance. That is why a sustainable and carefully selected light source forms the foundation of every successful lighting solution, whether for homes or public environments.
An energy-efficient light source, most commonly an LED lamp, dramatically reduces electricity consumption compared to traditional incandescent and halogen lamps. However, the benefits go far beyond lower energy bills. An energy-saving light source also offers an exceptionally long service life, reducing the need for replacements and, consequently, waste. Modern LED lamps provide instant, flicker-free illumination with excellent colour rendering, ensuring that colours appear natural and true to life. Their luminous efficacy, measured in lumens per watt, is simply superior, delivering more light while using less energy.
Today, the most common light sources are based on LED technology due to their high energy efficiency and durability. However, there are several types designed for different luminaires and applications.
The standard choice for general lighting. Available with all common lamp bases such as E27 (large screw base) and E14 (small screw base), they are often dimmable and provide high luminous output (lumens).
A type of LED light source designed to mimic the appearance of a traditional incandescent bulb, with visible “filaments.” Ideal for decorative lighting where the light source itself is part of the design.
Used less frequently today but still found in certain specialist luminaires. They provide warm light but have a shorter lifespan and higher energy consumption than LED alternatives.
A predecessor to LED technology as an energy-efficient light source. They are relatively efficient but contain mercury and often provide less accurate colour rendering.
A light source is the replaceable or integrated component of a lamp or luminaire that produces light, such as an LED lamp or a fluorescent tube.
Start by checking the luminaire’s base type (e.g. E27, E14, or GU10), the required brightness (lumens), and the desired colour temperature (Kelvin). Also verify whether dimmable light sources are needed.
Lumens (lm) measure luminous flux, meaning the amount of light emitted. Colour temperature is measured in Kelvin (K) and describes the colour appearance of the light, ranging from warm white light (approximately 2700 K) to cool, daylight-like illumination (above 4000 K).
An LED lamp has a very long service life, typically between 15,000 and 50,000 hours. This is significantly longer than traditional incandescent lamps, which rarely lasted more than 1,000 hours.
