LED glass lamp from the Eco-Line with filament optics, E27, 4 Watt The ultra-efficient light sources from the Eco-Line by Paulmann combine innovation with sustainability. Thanks to the 60% lower energy consumption and the significantly longer service life compared to standard LED lamps, energy costs can be significantly reduced and the environment can be protected at the same time. The visible filament and the generous globe made of solid glass provide an additional decorative eye-catcher, especially in luminaires with an open design. The warm white light, which is evenly diffused into the room, maintains the pleasant atmosphere.
