Vintage lamp with the right touch for readers. First customized for the Library of Congress, these quintessentially American lamps became a best-selling collection. The Library collection of lamps was created with scholars and researchers in mind, providing clean, bright and focused light without disturbing sensitive eyes. It’s enhanced by a patented lighting system, that rises like the sun when it turns on. Once the bulb light is on, the bulb takes about one minute to come to full brightness. This is due to the minerals found within the bulb that work together to provide the bright light. The slow build to bright light also serves the purpose of preparing your eyes for the bright light.
