Light sources – the right light for every socket

The right light sources determine brightness, lighting mood, and energy consumption – often more than the lamp itself. Here you will find modern LED light sources for all common sockets: E27, E14, GU10, G9 and other special sockets – from classic filament retrofits to special lamps for specific applications.

Finding the right light source

Luminous flux (lumens): More lumens mean more brightness. The lumen value is the fair benchmark for comparison – not the wattage.

Color temperature (Kelvin): 2700–3000 K appears warm and cozy, 4000 K neutral and professional. Choose the light color to suit the room and its use – in living areas, this is almost always the warmer option.

Color rendering (CRI): A high CRI (≥ 90) makes colors appear natural – important for living and work areas, and indispensable for bathrooms and kitchens.

Dimmability: Look for the "dimmable" label and compatibility with your dimmer. Not every LED light source works with every dimmer – when in doubt, check briefly.

Socket & design: Check the base and dimensions – especially important for spots, enclosed luminaires, and recessed lights.

Special applications: Heat-resistant oven lamps up to 300 °C are required for ovens and stoves – standard light sources are not suitable here.
