    • The viewing area shall produce a luminance of 60 Nits and not vary in luminance across the viewing area by more than a few percent.
    • Failure of one (1) LED shall not reduce the light output by more than eight percent (8%) per foot.
    • No wiring within the optical cavity will be permitted.
    • Anything other than the LEDs within the optical cavity will cause degradation in optical performance and will not be accepted.
  • The Sign shall have an input voltage of 120. The input voltage will then be reduced and power-conditioning circuitry will be provided so that the LED’s current will operate at the manufacturer’s recommended specifications.
  • The sign shall include a replaceable fuse at the electrical power wire entrance compartment.

Mechanical Construction

  • Aluminum
    • Top shall be extruded from 6063-T5 aluminum alloy with a minimum thickness of 0.140″. Drip rails overhanging the sign face help prevent water
    • Bottom extruded from 6063-T5 aluminum alloy with a minimum thickness of 094
    • Ends cast from 356 aluminum and have a minimum thickness of 188″.
    • Seams connecting top and bottom to ends shall be welded continuous to provide a weatherproof

  • Reflectors shall be constructed from 0.040″ aluminum and shall be wet-painted white.
  • Recommended mounting hardware is available from National Sign and Signal Co. This hardware allows swinging of the sign to reduce mast-arm wind loads. Brackets are adjustable for leveling the sign for use on any size mast-arm. Other mounting methods may be applicable.


All products will be warranted to be free of defects due to material and workmanship for a period of two (2) years.
