We have replaced the LED bulb three older energy-saving lamps. In conjunction with a white good translucent paper lampshade the bulb illuminates a 15sqm room very nice and bright and still pleasant warm tone. Compared to the previous Osram bulbs, which had reached its full brightness after 2-3 minutes, the full luminous flux is right now there. And light illuminate with 11 watts an entire room, for which we have previously required 3x9 Watt, shows that there are with new technology constantly savings. As for the durability, we have the pear since September 2013 daily use and so far it has no weaknesses. I therefore believe that 5 star justified.
