Application excellence
Uniform illumination
Easily replacing a 400W HID site fixture, the Prevail LED luminaire is the solution whether retro-fitting an existing site or lighting a
new location. Four optical distributions allow the lighting designer to put light exactly where it’s needed without wasting energy
with extra light spilling onto unwanted locations. An optional house-side shield is available when extreme cut-off is needed at the
property lines. Parking areas must be designed to provide safety and security to both pedestrians and vehicular traffic. Good
exterior lighting design will deter criminals, and attract patrons all while limiting light pollution. The IESNA has provided two
documents to aid in proper parking lot lighting design; RP-20 lighting for parking facilities and RP-33 lighting for exterior
environments. Proper illumination levels for site and area design are achieved by maintaining an absolute minimum illuminance
level at any given point within the site, while holding acceptable maximum-to-minimum uniformity levels. The Prevail LED
luminaire is ideal for parking lots, small retail, security, and roadway applications.
Greater than 68 percent in HID to LED retrofit savings
The following comparison shows the Prevail A40 luminaire and a 400W pulse start metal halide shoebox type luminaire in a
typical parking lot application. All fixtures are at the same mounting height and locations. The same number of poles and fixture
heads are used to calculate a one-for-one direct comparison. The Prevail luminaire not only provides a higher minimum and much
more uniform layout, but it also provides more than 68 percent in energy savings over the HID solution.
