Rio Tinto Energy America Mine Locations Save on...

FARMINGDALE, New Jersey, February 29 /PRNewswire/ --

    Dialight Corporation recently reached an agreement with Rio Tinto Energy
America to install its LED-based SafeSite(TM) and LEDBright fixtures
throughout many of its coal mining and crushing facilities, thus improving
safety dramatically and decreasing maintenance and energy costs in these
locations.



    The rugged solid-state design of these newly released fixtures creates a
new era where failed lamps and expensive re-lamping costs become a thing of
the past. Dialight's newest illumination fixture, the SafeSite series, is
designed exclusively for hazardous locations.



    Rio Tinto Energy America has begun to replace traditional high-pressure
sodium, metal halide and fluorescent lighting fixtures with the new SafeSite
and LEDBright fixtures to achieve a better, whiter grade of lighting with an
instant "On" feature so they can be used as needed.



    These rugged fixtures are perfect for applications such as this, where
shock and vibration are present. They provide extremely long life before
service is required. With the great reduction in power needed to operate
these new fixtures, they will assist Rio Tinto Energy America in efforts to
reduce energy use and greenhouse gas emissions.



    Specific applications at Rio Tinto Energy America include replacement of
Hi Bay Lighting (400-watt HID fixtures) in maintenance areas with LEDBright
fixtures; replacement of lighting on drill rigs where vibration shortens the
life of traditional lights; and replacement of lighting in wash bays with
LEDBright fixtures, thus eliminating the shock of hitting a hot fixture with
cold water.



    Future additional applications are presently being considered within the
Rio Tinto Energy America facilities.



    Rio Tinto Energy America is using SafeSite to replace traditional
high-pressure sodium, metal halide and fluorescent lighting fixtures in
maintenance areas and on drill rigs where vibration shortens the life of
traditional lights.



    SafeSite's rugged housing makes it ideal for applications like this where
shock and vibration are present. Designed to meet UL Class 1 Division 2
requirements, SafeSite uses state-of-the-art, solid-state LED lighting to
create a new era where failed lamps and expensive relamping are a thing of
the past.



    SafeSite incorporates the latest LED technology with proprietary optics
to achieve area lighting comparable with traditional light sources. By
focusing light where it is needed, SafeSite is the most efficient light
source available for hazardous area lighting applications.



    Doug Woehler, product manager at Dialight, says, "The emergence of LED
technology designed specifically for hazardous environments means that
companies like Rio Tinto Energy America can use SafeSite to make energy and
maintenance cost savings without compromising on their lighting needs. In
some environments where coal dust can create a potentially explosive
atmosphere, traditional lighting cannot be installed. SafeSite provides a
new, safe option to light these areas."



    The first of its kind, SafeSite is designed to replace 75W to 250W HID
light sources in hazardous location applications. The fixture provides better
quality light, higher fixture efficiency and 30% greater energy efficiency
than traditional HID light source technology.



    The SafeSite LED white downlight can be mounted on walls, stanchions and
pendent mounts. It provides an instant "On" response so it can be used as
needed rather than wasting energy when not required.



    Rio Tinto Energy America specializes in the production of low-sulphur,
sub-bituminous coal, and operates five coal mines located in Wyoming, Montana
and Colorado. With a combined workforce of more than 2,400 employees, and
with the help of hundreds of contractors and suppliers, the company provides
fuel to its energy company customers who generate nearly six percent of the
nation's electricity.
