DOTs and other agencies must now choose alternative lamp sources for the replacement of these fixtures and for new construction or additions. Under the Federal Energy Policy Act (EPACT 2005) and the Energy Independence and Security Act, conventional mercury vapor lamps and all 150-500 watt metal halide probe start ballasts were mandated to be substituted with more energy efficient alternatives.

The 70 or 100W StreetSENSE RS series LED fixture can typically replace a 250W or higher mercury vapor / metal halide unit while still meeting or exceeding the Roadway Sign Light Specifications, so it delivers CO2 reduction and energy savings of 60-70% over conventional lights. This efficiency is further enhanced by its instant-on/off ability with no necessary warm up to achieve full illumination. In addition its ‘green’ credentials are assured by the fact that it is 100% mercury free and dark skies friendly; this is assured by its highly efficient optics that focus the light just where it’s needed, avoiding light spill.

Maintenance Free
The rugged, solid state StreetSENSE RS series fixture is not only an energy efficient alternative, but its projected fixture service life of ten years (50% on-time, >70% lumen maintenance after 60K hours) also brings other significant benefits. These include the elimination of frequent lamp changes and reduction of overall maintenance costs as well as reducing exposure of maintenance workers to dangerous highway traffic. For road users they deliver added safety by producing a quality of light that is vastly superior to conventional sources and by eliminating dark road signs resulting from burned out conventional lamps.

Ease of Installation
Dialight offers complete fixture assemblies for new, retrofit or complete replacement applications including a unique LED retrofit cover assembly kit option that will adapt to most installed conventional fixture boxes. The retrofit involves only the removal of the existing fixture’s cover, lamp and reflector which is then replaced with the Dialight LED cover assembly, leaving most of the existing wiring connections untouched, so the conversion is simple and easy, saving both time and money.
