Quadcast LED
Parking Garage and Canopy Luminaire
Applications and Return-on-Investment Guide
Quadcast LED
The patent pending Lumark Quadcast™ Parking Garage and Canopy Luminaire is designed with industry-leading, innovative and
universal functionality while delivering energy-efficient optical control in a compact, low-profile, rugged form with easy installation
features. An industry-first quadrant of precise-aiming adjustable optical light panels, coupled with unparalleled energy savings and
easy payback make Quadcast LED the ideal solution for parking garage, canopy, stairwell or low-bay installations.
Parking Garage Applications
Recommended Illuminating Engineering Society of North America (IESNA) standards
in maintained horizontal and vertical illuminance levels for parking garage facilities
requires meeting rigorous uniformity and illumination levels. Quadcast LED is
supplied standard with field-adjustable LED optical panels that can be precisely
rotated and locked to directionally illuminate vehicular drive lanes and parking
bays while decreasing safety concerns in hard-to-reach entrance and exit doors to
stairwells that are often located in the corners of the space. Field-adjustable optical
aiming provides additional benefits on steep grade ramps and in drive lanes where
luminaire glare and visibility is a concern.

Performance and Savings
Precise aiming of the adjustable optical LED panels coupled with state-of-the-art, flow-through heat sink technology design makes
Quadcast LED the right solution for meeting horizontal and vertical footcandle levels. The Quadcast adjustable LED optics rotate
from straight down to an uplight position, eliminating the “cave effect” caused by dark ceilings and walls and allowing for an open
feeling of space while improving depth perception and pedestrian and vehicular safety. The total system input watts, fixture operating
life and luminaire performance should be considered when addressing energy consumption, safety and total cost of ownership.

Energy Savings
Reduced Energy Consumption
Operating and maintenance cost of a lighting system are dramatically impacted by the specified lamp source, system power
consumption and the duration time of operation. Total system input watts and fixture operating life should be the driving considerations
when addressing energy consumption and total cost of ownership. Energy savings increase when energy consumption is reduced and
maintenance intervals are extended.

NOTES: 1 System cost (annualized) = (fixture cost + install cost) x (number of fixtures).
2 Rebate = (rebate per fixture) x (number of fixtures).
3 Custom incentive rebate = ([(delta of input watts per fixture) x (200 fixtures) x (8760 hours)] / 1000) x $0.12 per kilowatt hour.
4 First year energy cost = (kWh per fixture) x (hours of use) x (fixtures) x (365 days) x ($0.10/kWh).
5 Maintenance cost dependant upon lamp life of fixtures listed in Table 1.
6 Energy and maintenance savings = cost of energy and maintenance for existing fixture - cost of energy and maintenance for Quadcast.
7 Maintenance cost for the T12 includes the replacement of the lamp, ballast and sockets due to T12 luminaire discontinuation.
8 The 179D tax credit ($0.60/square foot) may be available for your project. Eligibility for the 179D tax credit is dependent upon an installed system capability of 50%
dimming. Credit = ($0.60/SF) x (900 SF/fixture) x 35%(tax rate) = $189/fixture. 900 square feet is based on a 30' x 30' illumination level for a single Quadcast fixture.
The tax rate is based on that of the consumer. See IRS Bulletin 2006-26 (http://www.irs.gov/irb/2006-26_IRB/ar11.html) for more information.
9 Utility rebates may be available in your specific area for new construction projects. Check with your local utility provider for more details.

FAQs
What is an LED?
An LED is a solid state semi-conductor device invented circa 1962 that produces light without the use of a filament, as incandescent
lamps, or electrodes used in gas discharge lamps (HPS, metal halide and fluorescent). This makes the device very rugged and durable.
Since their invention, LEDs have been used as numerical displays, indicator lights, traffic signals, automotive tail lights, outdoor sign
channel letter backlights, cell phone backlights and in many other applications.
Can LEDs be used in outdoor lighting?
LEDs have been used in outdoor applications such as electronic billboards and sign backlighting for many years. As with any electronic
device, however the design of the finished product must be suitable for the environment. Cooper Lighting considers it vital to the
successful implementation of the LEDs into outdoor products that real world environments be considered and designed for:
• Ambient Temperature: Quadcast LED luminaires are rated for -30°C to 40°C (-22°F to 104°F), meaning all predicted component
lifetimes are evaluated at these temperatures making the products suitable for the widest range of environments.
• Water Intrusion: Quadcast LED is tested and rated for use in wet locations. Quadcast is IP66 Rated.
How does Quadcast LED dissipate heat?
Quadcast LED utilizes a passive cooling method on optical LED panels. Passive cooling uses the surface area of a heat sink and air
convection to cool the LED. By avoiding fans and mechanical methods of cooling the LED, the reliance on a part that could fail over
the lifetime of the product is eliminated.
What is an LED driver?
LEDs require an electronic power supply to operate and regulate the luminaire. This is similar to the ballast required for HID and
fluorescent lamped luminaires. In the case of LEDs, the power supply is commonly referred to as a driver.
How long can the LEDs in Quadcast LED continue to operate?
The real answer is “it depends.” The expected lifetime of an LED depends primarily on two things, 1. How hot it gets
(thermal management); and 2. How hard it is driven (electrical stress). Cooper Lighting evaluates both of these properties in a
realistic 40°C (104°F) ambient temperature such that a predicted lifetime of both the LED and the driver exceeds 60,000 hours of
operation.
How is lumen maintenance determined for LED?
Like all light producing devices, an LED does gradually produce less light as it ages. The Illuminating Engineering Society of North
America (IESNA) has established guidelines for lumen maintenance. LM-80 and TM-21 are two standards that are used in tandem
to determine lumen maintenance for LED light sources. The purpose of the LM-80 is to establish uniform test methods for LED light
sources and allow a reliable comparison of the test results among laboratories. TM-21 is an IESNA technical manual that uses the data
collected from LM-80 and provides a method to determine the useful lumen maintenance of an LED.
