This lamp Replace conventional "energy saving lamp". It is immediately clear, without start-up time and the light color is more in accordance with an incandescent light. Under no circumstances garish, rather a pleasant warm tone. The lamp is operated under a lampshade, so the built-in LEDs can not directly see it. These are of close regarded not as "nice" (matter of taste). Very suitable for lamps with shades (z. B. bedside lamps). The size is such that it corresponds to a conventional lamp and a lamp shade can be plugged. Durability I will report later if necessary.
