This lamp provides a good amount of light, such that it can be the only light in a 12 x 15 room.
The one feature I don't like is the light is a glaringly harsh white light.  Its not the sort of light one would want to have as the only lamp in the room.

From a price point and functionality point of view, it is a bargain.   I guess in order to get a softer, more soothing light quality, the price point would need to be much higher.
