LEDs open new doors

The widespread use of white-light inorganic light-emitting diodes in architectural spaces is generating a great deal of optimism in some government and industry circles. Many from the commercial world are more cautious and await significant improvements to white LED lighting fixtures, including higher luminous efficacy, greater flux generation, longer life, better color consistency and lower cost. While the development of these devices continues, color inorganic LEDs are already enjoying significant growth in signage and signals applications and may begin to expand into unacting, where it is previously impractical to employ color or not even recognized as useful.
