Looking at his extensive library one day, designer Roderick Vos realized that a scattering of small lights would showcase the books and aid readers. So he created Mr.Ed: a light bulb held in place by two vertical, book-like shapes. Equally at home on a bookshelf or bedside table, Mr. Ed has enough brute strength to act as a bookend.
Although Mr.Ed can use any 40 Watt bulb, Vos prefers an incandescent bulb for its warm glow. In fact, Vos named Mr.Ed after the inventor of the incandescent, Thomas Alva Edison.
