The USB Flex Neck Light uses LEDs, which never get hot or burn out, and last more than 20,000 hours. The light is powered by USB port or batteries housed in the detachable clip. “The USB Flex Neck Light is the perfect solution for the student on-the-go,” Lightwedge Marketing Communications Director Nicky Shifman told TDmonthly. “Plug it into the USB port on a laptop for late-night studying or, use the detachable clip to attach to a book for reading in bed.” Launch date: April 2008.
