Silly purchase -- does not add any light to a open room, possibly would in a small closed room.  You have to be very close to it with the remote to get it to work which is a bad feature, especially if the lamp is placed at one end of a room and seating is not close.  It has become a toy at this point, if my grandchildren want to look at the colors, I let them but no one ever bothers to turn it on.  I do not recommend this, it's pointless.
