LED Conversions

Your outdoor sign may still be working, but is it looking its very best? It might not be lighting evenly, or isn't as bright. At a certain point, you've probably considered upgrading your signage to energy-efficient LEDs.

There are many reasons to upgrade to LEDs

  • ENERGY EFFICIENCIES: LEDs produce more light per watt of electricity than traditional light sources, resulting in energy savings as high as 7x over conventional lighting.
  • MAINTENANCE SAVINGS: Properly operated and designed LEDs will last up to 50,000 hours or longer.
  • REBATES AVAILABLE: To find out if you are eligible for a rebate or other incentive program, you can reference the Department of Energy's DSIRE site.
  • LEDs ARE BRIGHTER IN COLD TEMPERATURES: LEDs do not dim in cold weather and perform well in extremely cold conditions.
  • ECO-FRIENDLY: LEDs are environmentally friendly and do not contain mercury as some fluorescent and neon tubes do.
  • IMMENSE SAVINGS: Dependability and performance you can count on at prices you can afford!
