Tesla Filament A class, E27, 4W, 840lm, 6500K cool white, 360deg, clear, 230V, 25 000h

The Tesla Lighting Filament LED bulb with an E27 base combines technology and a retro look. With a power consumption of just 4W, it provides a luminous flux of 840lm, placing it in the highly efficient energy class A. It emits a cool white light with a colour temperature of 6500K, which is suitable for workspaces or rooms requiring bright lighting. The filament technology mimics the appearance of a traditional tungsten bulb and ensures even light distribution at a 360° angle. With a lifespan of up to 25,000 hours, it offers long-lasting performance.

Filament Technology and Even Light Distribution

The bulb uses Filament technology, where the LED chips are arranged to form filaments. This design not only mimics the look of classic tungsten bulbs but also offers functional advantages. Thanks to the arrangement of the light sources, it achieves even illumination at a 360° angle. This means the light spreads in all directions without the shadows that can be created by standard LED bulbs with a limited beam angle. A colour rendering index (CRI) of 80 Ra means that the colours of illuminated objects appear natural and without significant distortion. The cool white colour of the light (6500K) promotes concentration and is ideal for lighting areas where bright, focused illumination is needed.
