The World famous Duval St (the only street that runs from coast to coast) in the City of Key West, Florida had four major critical design needs when this project was initiated.

  • First, during major city wide events and festivals power outages would frequently black out Duval St for an hour or more creating a potentially dangerous situation.
  • Second, due to the current lamp technology of MH lamps were often out or at minimal light output and the limited city electrical staff had a constant maintenance task.
  • Third, lighting at certain key areas such as intersections, gathering spaces and key attractions were glary and had hot spots and dark areas.
  • Fourth, the local electric rate of 12 cents per KWH accelerated the ROI of this project.

The solutions lead to the newest technology – LED Lighting.

The Architectural Board created a specification which included the Emergency Battery Back-up system. The project was competitively bid and the Beacon Products Waterford was selected because of its Historic look and size was sufficient to house the needed Battery Pack. Utilizing a 48W light engine, replacing the 150W MH, energy consumption was reduced by more than 70% and the 60,500 hr. life virtually eliminated maintenance.

A Type V lighting distribution with a frosted acrylic lens increased light levels and reduced glare, thereby actually increasing the visual acuity and safety on the street. Mr. Brett Wright, Facility Maintenance Supervisor, stated that the city is very pleased with the installation and the overall performance.

Benefits:

The Waterford Series provides exceptional quality illumination, stability, durability and cost savings. The Waterford uses up to 75% less electricity than its metal halide counterparts. And unlike conventional lighting, there is negligible light loss over the life of the LEDs. It provides reliable, durable, maintenancefree illumination for more than 60,500 hours. The integral Emergency Battery Pack will provide a reduced light level for a minimum of 90 minutes. The Waterford is not affected by vibrations and typical temperature variations and is available in color temperatures from “warm” to “cool” with a high color rendering index (CRI), guaranteeing high–quality white light. It’s also so water-tight that harsh wind driven rains remove the dirt and grime that impede illumination and jeopardize pedestrian and vehicle safety.
