The first I've taken because I wanted to try it and wanted to replace the much too slow brightly expectant energy saving lamp in the bathroom of my mother. Light: class, immediately Hell, great! Meanwhile, I've replaced in my house ALL E14 against it here. Exception: hood. There is only a small light hole is in there that I need the brightest available matching E14, and this is (for now) still an energy-saving lamp with Zwirbelröhre. But my enthusiasm for this LED here is unbroken: Pleasant light (in the bedroom), immediate light output, long life: Who needs light bulbs or energy-saving lamps? I, the LED is no longer grown.
