CUTOFF POST TOP LUMINAIRES
THE STANDARD OF EXCELLENCE
THE COMMUNITY STANDARD
Bridging the gap between aesthetic ambiance and
uniform low glare illumination can prove to be very
difficult: until now! Streetworks is proud to introduce
the next generation of optical control:
The Generation Series CVL Optical System.
Generations Series CVL is first and foremost a true IES
cutoff luminaire providing the dark sky benefits and
light control that many communities now demand.
The Type III and Type V optical systems utilize specular
reflectors and a vertical lamp orientation to achieve the
optimal combination of low brightness and
efficiency.
THE MAINTENANCE STANDARD
Ease of maintenance was a leading design
consideration for the Generation Series. Three (3)
heavy-duty, spun aluminum tops are available with
removable caps to allow easy access to the lamp
without having to remove the globe. Access to the
NEMA style photocontol and starter is a simple twist
away via the Generation housing’s side entry door
assembly.
THE CONSTRUCTION STANDARD
Architectural post-top units must be constructed to
survive the test of time. That is why the Generation
Series uses heavy-duty cast and spun aluminum
materials to provide the rigid construction that insures
years of use.
LAMP ORIENTATION
The Generation Series utilizes a vertical lamp
position and locates the lamp in the luminaire
top to prevent any direct glare to pedestrians or
motorists. The vertical lamp orientation
allows for wider spacing and better uniformity
over traditional horizontally lamped cutoff
luminaires.
IES CLASSIFICATION
As a result of the Generation Series exceptionally
low brightness, visual perception is enhanced as
contrast between the luminaire and surrounding
objects is reduced. As an example, a collector road
with a medium pedestrian conflict area can be designed to IESNA RP8 standards while still
spacing the luminaires 6 mounting heights apart.
Combining this strong performance on the ground with it’s IES cutoff classification makes the
Generation Series the ideal choice for the environmentally conscience.
