Engadget - Four hundred and fifty dollars. Made out to Lumiotec, please. Really, that's all you need to know -- this tiny purposeless OLED lamp costs nearly half a grand. But hot damn does it look good. If you have the cash and don't mind shelling it over, Lumiotec's OLED Hanger lamp is a mighty cool gadget to own. Until you realize that you're not really sure what to do with it.
