When we first got our hands on this product, we didn't believe that someone would come up with an idea of powering lamps by phone line. Well, the fun is that you don't pay for the power (or batteries) used, and since usually when electricity is out phone lines still work, it will light the dark during those emergencies. In my opinion, since it costs nothing to power and its LED bulbs lasts forever, its a great night lamp for any room. Better yet, when your phone rings, the lamp flashs giving you some extra visual feedbacks. When the phone line is in use, however, the light automatically switches itself off, possibly to prevent affecting voice quality of the line.

One side note: in some occasions the lamp (switched on) seems to interfere with the caller ID feature. We are unsure of whether this applies to all phones or not.
