Dialight is First to Supply LEDs for Illumination on Drilling Rigs

FARMINGDALE, New Jersey, February 28/PRNewswire-FirstCall/ --

In the first installation of its kind, Dialight Corporation's new
LED-based SafeSite(TM) illumination fixture has been successfully retrofitted
on a drilling rig of a major oil and natural gas producer, providing improved
safety and decreased maintenance and energy costs.

SafeSite is designed to operate in the harsh and hazardous environments
found on drilling rigs, where vibration is the major cause of failure for
traditional light sources. The SafeSite fixture has a very robust housing
designed to UL Class 1 Div 2 standards, and since the LED light source is a
solid-state device it is virtually impervious to shock and vibration, making
expensive re-lamping costs a thing of the past.

SafeSite utilizes the latest LED technology with proprietary optics to
focus the light to illuminate only the required area. The 100-watt SafeSite
fixture can replace traditional HID fixtures that require up to 250 watts for
a potential power savings of up to 60%. In addition, LEDs do not require a
warm-up period and can be operated as "instant on," allowing for further
savings over HID sources.
