Contrary to what the product description states, the Littlite gooseneck lamps actually comes with a PSU. As it is for american sockets, it might as well not be there at all. Luckily you can buy this little fellow to use your Littlite in our part of the world. It does it's job without complaining.
(I couldn't really give a high "light output" rating to a mere PSU, now could I?)
