Actually, the lamp was only intended as a substitute for a cold-as energy-saving lamp that I do not often use.
But bothered me that I cold-setting wanted real daylight-looking as I have this light feel most comfortable.
That's why I decided to read long for this lamp.
I was very skeptical whether the lamp really at 13 watts 1110 lumens delivers as indicated.
While I can not measure it but the wattage, the light intensity I really find very bright.
Even brighter than old 100 watt bulbs.
The upshot is that this lamp has become my home lighting because it is lighter than my old LED strips which I had glued directly over my desk at the ceiling.
And had to more watts.
So why use more electricity if you then get less light.
Thus with me only burns the TIWIN pear.
For durability, I can not say much.
we'll see in a two years.
For me, the lamp burns very often because the room is pointing north.
Something that I can not place the lamp slightly climbs if you have turned off the power.
I do not know if that's a good or bad sign of LED lamps.
Perhaps the setting here so someone.
