In our hall there has always been a bit dark, I used a standard 100 Watt lamp for illumination, which was quite ok. Then came a Energeisparlampe who unfortunately was unable to find the luminosity and color of light. The sebson lamp now is really light in the hallway, in my opinion, even more than the earlier 100 Watt lamp. And the great advantage over the energy-saving lamp (just in the hallway, where no light constantly burning) is that it is now quite light. Am really excited!
