Sehr gute Birne in einem schönen warmweiß, was bei LED-Lampen eben meist nicht der Fall ist. LED Lichter sind übrigens auch schädlich für die Augen. Durch die ganze Klimaagenda bekommt man ja keine normalen Leuchtstoffröhren mehr, gut dass man wenigstens noch Energiesparleuchtstoffröhren bekommt. Die machen defintiv ein ganz anderes Licht, wirklich angenehm.
