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°

SPILL + GLARE CONTROL

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.

Controls excess spill and glare on top portion

of distribution. Especially useful in uplighting

applications to limit light travel above an

4-SIDED SHIELD

Controls lamp glare and spill light in all

directions. Useful when aiming direction or

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.
