FLUENT FORM
VISION Flood’s cylindrical form blends effortlessly to architectural and landscape environments.
Available in wattages up to 1000 watt Metal Halide and in two (2) housing sizes, VISION Flood offers
properly scaled solutions for any floodlighting application.
EXCEPTIONAL DESIGN
Designed for sustaining quality, VISION Flood’s precisely engineered die-cast aluminum
housing and door incorporate IP65 rated gasketing strategies, while the heavy duty knuckle provides
infinite aiming flexibility and lock-down strength tested to withstand 3G of vibration.
OPTICAL FLEXIBILITY
Designed to offer community friendly optical control, VISION Flood optics focus lamp output
into defined rectangular patterns while controlling direct visibility of the lamp, a root cause of glare
and light pollution. Six (6) available optical systems provide maximum design flexibility, while a
broad array of light control accessories provide supplemental cutoff control.

Footcandle levels are ultimately dependent upon the projected distance, aiming angle, and luminous intensity of a lamp/reflector combination.
A cursory understanding of the equation which relates these variables provides insights to proper design technique and distribution selection.
Holding other variables constant, as the projected distance increases from the luminaire to the surface being illuminated, a greater amount
of luminous intensity (I, Candela) is required to sustain an equal illuminance (E, Footcandle) level.
INVERSE SQUARE COSINE LAW
E=I cos (x)/D2 -or-
Illuminance (Footcandles, fc) = Luminous Intensity (Candelas, Cd) * cos (incident angle X) / Distance2
Holding incident angle X constant at 30˚ while increasing the projected distance D from 10' to 20' requires an increase in candela from
577 to 2310 respectively to sustain an equal 5 footcandles (fc) of illumination at the target point.
The incident angle as measured from a luminaire’s directed intensity to the target surface normal also plays a significant role in determining
illuminance values. Holding other variables constant as the incident angle from the target surface to the projected aiming line increases, so does
the amount of luminous intensity (I, Candela) required to sustain an equal illuminance value.
Holding projected distance D constant at 10' while increasing incident angle X from 30˚ to 45˚ requires an increase in candela from
577 to 707 respectively to sustain an equal 5 footcandles (fc) of illumination at the target point.

- NEMA [IES] Classifications
FLOODLIGHTING TERMINOLOGY
NEMA [IES] CLASSIFICATIONS
NEMA classifications are extrapolated from the table below and are determined by a distribution’s Field Angle. This relative classification is used
to describe the general shape and application of a distribution. NEMA classifications are used to classify both the horizontal and vertical
components of a floodlight distribution.
The example distribution in FIG. 1 above would have a NEMA Classification of 6 as the 120° Field Angle falls between the 100-130° range.
FLOODLIGHTING TERMINOLOGY
Ever wonder how NEMA (H x V) Classifications are derived, or how they relate
to the performance and design application of a floodlighting distribution?
How about beam and field angles, and maximum candela values?
-Maximum Candela is defined as the maximum candela value emitted
from the luminaire in any given direction.
- Beam angle is defined as the included angle between points of 50%
of Maximum Candela.
- Field Angle is defined as the included angle between points of 10%
of Maximum Candela.
As an example, a distribution with a 50,000 Cd maximum candela value
as shown in the intensity distribution graph to the right (FIG. 1) would have a
Beam Angle defined by the included angle of 25,000 Cd values, and a Field
Angle defined by the included angle of 5,000 Cd values.
EXAMPLE
Max Candela = 50,000 Cd
Candela Value defining Beam Angle = (50% * 50,000 Cd) = 25,000 Cd
Candela Value defining Field Angle = (10% * 50,000 Cd) = 5,000 Cd
Beam Angle = 90°

VISION FLOOD Architectural Flood Luminaire
Limiting the amount of stray light which falls beyond the boundaries of the intended target is not only good design practice, but is increasingly
a mandate of local and state adopted lighting ordinances. The VISION Flood series offers a family of beam control options to limit unwanted stray
light and control direct viewing of the lamp, a common source of discomfort and disability glare.
EXTERNAL GRID LOUVERS
Designed to control lamp glare and spill light
while maintaining beam efficiency. Useful when
aiming direction or intended target lies in close
proximity to pedestrian and/or motor vehicle
activity. Mounts to accessory channel in
doorframe. Compatible with all distributions.
Available on VFM only.

INTERNAL LOUVERS
Standard on Narrow Spot and Narrow Flood
distributions, integral ring louver controls lamp
glare while eliminating spill light outside the
main beam.
VISION Flood offers a host of beam control options that limit
unwanted stray light and control direct viewing
of the lamp source.

TOP VISOR
Controls excess spill and glare on top portion
of distribution. Especially useful in uplighting
applications to limit light travel above an
intended wall surface or sign. Mounts to
accessory channel in doorframe. Compatible
with all distributions.

4-SIDED SHIELD
Controls lamp glare and spill light in all
directions. Useful when aiming direction or
intended target lies in close proximity to
pedestrian and/or motor vehicle activity.
Mounts to accessory channel in doorframe.
Compatible with all distributions. Available on
VFM only.
RECTANGULAR BEAM PATTERNS
Structures, signs, and other various objects which
dominate our visual landscape are largely defined
by straight lines and planar surfaces. Lighting
these objects with rectangular distributions
eliminates excess spill light while maintaining
optimal uniformity.

Typical Round Beam Patterns
Rectangular Beam Patterns
Typical round patterns create shadows in
corners, requiring closer fixture
spacings. Uniformity is compromised.
Rectangular beams produce more
uniform coverage, resulting in reduced
fixture counts and less stray light
spilling beyond the intended target.

ILLUMINATION RECOMMENDATIONS
Effective floodlighting design is a complex and subjective task. Results are heavily dependent upon surrounding light levels, surface finish of the
intended target, spectral color distribution of the lamp source, mounting location allowances, and viewers perceptions.
The following table lists IESNA (Illuminating Engineering Society of North America) recommended illuminance levels for the floodlighting of
buildings and monuments.
Cooper Lighting Application Engineers are available to assist in providing design layouts, aiming diagrams, and illuminance plots for your next
floodlighting project. Consult your INVUE Lighting Systems Representative for more information.
