Isolite was founded in 1982 to handle the worldwide marketing and distribution of Self-Luminous Safety Signs manufactured by Safety Light Corporation. Safety Light, in turn traces its roots back to 1918, making it the oldest radio-luminescent manufacturer in North America. \r\n\r\nThroughout its history, Safety Light has been a pioneer in the field of radio-luminescent compounds. These - non-electrical light sources have been used for more than 50 years in the aviation industry and in military applications where reliability is absolutely essential. Continous research and development in this highly specialized field led to the current generation of products developed to meet the needs of today's energy conscious users while providing the most dependable emergency lighting source available.\r\n\r\nIsolite also offers a full line of electrical LED emergency lighting. These are the most energy efficient electrical signs available and offer tremendous savings over the older incandescent and fluorescent lighting technologies. We offer many alternatives from the most economical plastic signs to the most elegant die-cast aluminum and edgelit housings.\r\n\r\nThese self-luminous products are unique. They require no external power or batteries and no maintenance. Our signs have successfully passed the most rigorous ANSI N-540 tests for structural integrity before being approved and licensed by the Nuclear Regulatory Commission.
