When moving into my house, I had almost everywhere screwed as a transitional solution bulbs. All between 40 and 75 watts.
I would other potential customers here and now willing to report that this lamp a 40, 50, 60 or even replaces a 75 watt bulb but I can not unfortunately.
The reason is simply that this LED light bulbs are not the same color as a light bulb. I personally feel a hint "colder" than like the light bulbs. It being understood that "colder" here actually does not fit, the light has really very pleasant and people who do not know that this is a LED bulb is screwed do not even notice probably.
I have this LED bulbs currently on the table (3x), the WC, storage room (3x) and mounted in the bedroom and I am fully satisfied in all rooms.
So in sum, I must say that this lamp can replace all light bulbs mentioned (the 40 used by me - 75 Watt), it just depends very much on the environment (light reflection) or how to feel the light.
For life I can not say much at the time logically.
From me a clear buy recommendation because this lamp has a great light output, looks tidy condition, and because I was the price of almost 10 EUR now not so frightened. Add to this the pleasant mood light and the 360 ° viewing angle.
