Compared to normal LED lamps, they are particularly characterised by higher efficiency, a wider beam angle and even lower power consumption. The vertical arrangement of the filaments distributes the light homogeneously in all directions and the optics are strongly reminiscent of earlier incandescent lamps. The LEDs immediately unfold their full light output and generate significantly less heat than conventional incandescent lamps or energy-saving lamps. No UV radiation. Free of mercury. Outdoor use in at least IP44 protected outdoor luminaires and for filament lamps without plastic content even directly outdoors is possible.
