FEATURES & SPECIFICATIONS
INTENDED USE — The BLT Best-in-Value Low Profile LED luminaire features a popular center basket design
that offers a clean, versatile style and volumetric distribution. High efficacy LED light engines deliver energy
savings and low maintenance compared to traditional sources. An extensive selection of configurations and
options make the BLT the perfect choice for many lighting applications including schools, offices and other
commercial spaces, retail, hospitals and healthcare facilities. The low profile BLT design (2-3/8") also makes
it an excellent choice for renovation projects.
CONSTRUCTION — BLT enclosure components are die-formed for dimensional consistency and painted
after fabrication with a polyester powder paint for improved performance and protection.
The reflector is finished with a high reflective matte white powder paint for improved aesthetics and
increased light diffusion.
End plates contain easy-to-position integral T-bar clips for securely attaching the luminaire to the T-grid.
For additional T-grid security, optional screw on T-bar clips are available.
Diffusers are extruded from impact modified acrylic for increased durability.
LED boards and drivers are accessible from the plenum.
OPTICS — Volumetric illumination is achieved by creating an optimal mix of light to walls, partitions
and vertical and horizontal work surfaces – rendering the interior space, objects and occupants in a more
balanced, complimentary luminous environment. High performance extruded acrylic diffusers conceal LEDs
and efficiently deliver light in a volumetric distribution. Four diffuser choices available - curved and square
designs with linear prisms or a smooth frosted finish.
ELECTRICAL — Long-life LEDs, coupled with high-efficiency drivers, provide superior quantity and quality
of illumination for extended service life. 70% LED lumen maintenance at 60,000 hours (L70/60,000). Color
Variation within 3-step MacAdam ellipse (3SDCM).
Non-Configurable BLT: Generic 0-10 volt dimming driver. Dims to 10%
Configurable BLT: available in High Efficiency (HE) versions for applications where a lower wattage (over
the standard product) is required. The High Efficiency versions deliver >130 LPW and can be specified via
the Lumen Package designations in the Ordering Information below.
eldoLED driver options deliver choice of dimming range, and choices for control, while assuring flicker-free,
low-current inrush, 89% efficiency and low EMI.
Optional integrated nLight®controls make each luminaire addressable - allowing it to digitally communicate
with other nLight enabled controls such as dimmers, switches, occupancy sensors and photocontrols.
Connection to nLight is simple. It can be accomplished with integrated nLight AIR wireless or through
standard Cat-5 cabling. nLight offers unique plug-and-play convenience as devices and luminaires
automatically discover each other and self-commission, while nLight AIR is commissioned easily through
an intuitive model app.
Lumen Management: Unique lumen management system (option N80) provides on board intelligence that
actively manages the LED light source so that constant lumen output is maintained over the system life,
preventing the energy waste created by the traditional practice of over-lighting.
Step-level dimming option allows system to be switched to 50% power for compliance with common energy
codes while maintaining fixture appearance.
Driver disconnect provided where required to comply with US and Canadian codes.
SENSORIntegrated sensor (individual control): Sensor Switch MSD7ADCX ((Passive infrared (PIR))
or MSDPDT7ADCX ((PIR/Microphonics Dual Tech (PDT)) integrated occupancy sensor/automatic dimming
photocell allows the luminaire to power off when the space is unoccupied or enough ambient light is entering
the space. See page 4 for more details on the integrated sensor.
Integrated Sensor (nLight Wired Networking): This sensor is nLight-enabled, meaning it has the ability
to communicate over an nLight network. When wired, using CAT-5 cabling, with other nLight-enabled
sensors, power packs, or WallPods, an nLight control zone is created. Once linked to a Gateway, directly or
via a Bridge, the zone becomes capable of remote status monitoring and control via SensorView software.
See page 4 for the nLight sensor options.
Integrated Smart Sensor (nLight Air Wireless Platform): The rES7 sensor is nLight AIR enabled, meaning
it has the ability to communicate over the wireless nLight control platform. It is both a digital PIR occupancy
sensor/automatic dimming photocell. It pairs to other luminaires and wall switches through our mobile
app, CLAIRITY, which allows for simple sensor adjustment. See page 4 for more details on the Integrated
Smart Sensor.
INSTALLATION — The BLT’s low profile design of only 2-3/8” provides increased installation flexibility
especially in restrictive plenum applications. The BLT fits into standard 15/16” and narrow 9/16” T-grid
ceiling systems.
Suitable for damp location.
For recessed mounting in hard ceiling applications, Drywall Grid Adapters (DGA) are available as an accessory.
See Accessories section.
LISTINGS — CSA Certified to meet U.S. and Canadian standards. IC rated.
DesignLights Consortium® (DLC) Premium qualified product. Not all versions of this product may be

The nES 7 is ideal for small rooms without obstructions or areas with primarily walking
motion. Ideal areas include hallways, corridors, storage rooms, and breakrooms.
Additionally, the NES7ADCX includes an integrated photocell, which enables daylight
harvesting controls.
For areas like restrooms, private offices, open offices, conference rooms or any space
with obstructions, the nES PDT 7 dual technology sensor is recommended. The nES PDT 7
utilizes both PIR (passive infrared) and Microphonics technologies to detect occupancy.
Additionally, the NESPDT7ADCX includes an integrated photocell, which enables daylight
harvesting controls which is ideal for areas where windows are present.
nLight AIR Wireless
nLight AIR is the ideal solution for retrofit or new construction spaces where adding
additional wiring can be labor intensive and costly. The integrated rES 7 smart sensor is
part of each luminaire in the nLight AIR network, which can be grouped to control multiple
luminaires. The granularity of control with the digital PIR occupancy detection and daylight
sensing makes a great solution for any application.

How to Calculate Delivered Lumens in Emergency Mode
Use the formula below to determine the delivered lumens in emergency mode
Delivered Lumens = 1.25 x P x LPW
P = Ouput power of emergency driver. P = 10W for E10WLCP option.
LPW = Lumen per watt rating of the luminaire. This information is available on
the ABL luminaire spec sheet. LPW = Lumen per watt rating of the luminaire. LPW
information available in Performance Data section.

FEATURES & SPECIFICATIONS
INTENDED USE —The BLT Best-in-Value Low Profile LED luminaire features a popular center basket design
that offers a clean, versatile style and volumetric distribution. High efficacy LED light engines deliver energy
savings and low maintenance compared to traditional sources. An extensive selection of configurations and
options make the BLT the perfect choice for many lighting applications including schools, offices and other
commercial spaces, retail, hospitals and healthcare facilities. The low profile BLT design (2-3/8") also makes
it an excellent choice for renovation projects.
CONSTRUCTION — BLT enclosure components are die-formed for dimensional consistency and painted
after fabrication with a polyester powder paint for improved performance and protection.
The reflector is finished with a high reflective matte white powder paint for improved aesthetics and
increased light diffusion.
End plates contain easy-to-position integral T-bar clips for securely attaching the luminaire to the T-grid.
For additional T-grid security, optional screw on T-bar clips are available.
Diffusers are extruded from impact modified acrylic for increased durability.
LED boards and drivers are accessible from the plenum.
OPTICS — Volumetric illumination is achieved by creating an optimal mix of light to walls, partitions
and vertical and horizontal work surfaces – rendering the interior space, objects and occupants in a more
balanced, complimentary luminous environment. High performance extruded acrylic diffusers conceal LEDs
and efficiently deliver light in a volumetric distribution. Four diffuser choices available - curved and square
designs with linear prisms or a smooth frosted finish.
ELECTRICAL — Long-life LEDs, coupled with high-efficiency drivers, provide superior quantity and quality
of illumination for extended service life. 80% LED lumen maintenance at 60,000 hours (L80/60,000). Color
Variation within 3-step MacAdam ellipse (3SDCM).
Non-Configurable BLT: Generic 0-10 volt dimming driver. Dims to 10%
Configurable BLT: available in High Efficiency (HE) versions for applications where a lower wattage (over
the standard product) is required. The High Efficiency versions deliver >130 LPW and can be specified via
the Lumen Package designations in the Ordering Information below.
eldoLED driver options deliver choice of dimming range, and choices for control, while assuring flicker-free,
low-current inrush, 89% efficiency and low EMI.
Optional integrated nLight®controls make each luminaire addressable - allowing it to digitally communicate
with other nLight enabled controls such as dimmers, switches, occupancy sensors and photocontrols.
Connection to nLight is simple. It can be accomplished with integrated nLight AIR wireless or through
standard Cat-5 cabling. nLight offers unique plug-and-play convenience as devices and luminaires
automatically discover each other and self-commission, while nLight AIR is commissioned easily through
an intutitive mobile app.
Lumen Management: Unique lumen management system (option N80) provides on board intelligence that
actively manages the LED light source so that constant lumen output is maintained over the system life,
preventing the energy waste created by the traditional practice of over-lighting.
Step-level dimming option allows system to be switched to 50% power for compliance with common energy
codes while maintaining fixture appearance.
Driver disconnect provided where required to comply with US and Canadian codes.
SENSORIntegrated sensor (individual control): Sensor Switch MSD7ADCX ((Passive infrared (PIR))
or MSDPDT7ADCX ((PIR/Microphonics Dual Tech (PDT)) integrated occupancy sensor/automatic dimming
photocell allows the luminaire to power off when the space is unoccupied or enough ambient light is entering
the space. See page 4 for more details on the integrated sensor.
Integrated Sensor (nLight Wired Networking): This sensor is nLight-enabled, meaning it has the ability
to communicate over an nLight network. When wired, using CAT-5 cabling, with other nLight-enabled
sensors, power packs, or WallPods, an nLight control zone is created. Once linked to a Gateway, directly or
via a Bridge, the zone becomes capable of remote status monitoring and control via SensorView software.
See page 4 for the nLight sensor options.
Integrated Smart Sensor (nLight Air Wireless Platform): The rES7 sensor is nLight AIR enabled, meaning
it has the ability to communicate over the wireless nLight control platform. It is both a digital PIR occupancy
sensor/automatic dimming photocell. It pairs to other luminairs and wall switches through our mobile
app, CLAIRITY, which allows for simple sensor adjustment. See page 4 for more details on the Integrated
Smart Sensor.
INSTALLATION — The BLT’s low profile design of only 2-3/8" provides increased installation flexibility
especially in restrictive plenum applications. The BLT fits into standard 15/16" and narrow 9/16" T-grid
ceiling systems.
Suitable for damp location.
For recessed mounting in hard ceiling applications, Drywall Grid Adapters (DGA) are available as an accessory.
See Accessories section.

The nES 7 is ideal for small rooms without obstructions or areas with primarily walking
motion. Ideal areas include hallways, corridors, storage rooms, and breakrooms.
Additionally, the NES7ADCX includes an integrated photocell, which enables daylight
harvesting controls.
For areas like restrooms, private offices, open offices, conference rooms or any space
with obstructions, the nES PDT 7 dual technology sensor is recommended. The nES PDT 7
utilizes both PIR (passive infrared) and Microphonics technologies to detect occupancy.
Additionally, the NESPDT7ADCX includes an integrated photocell, which enables daylight
harvesting controls which is ideal for areas where windows are present.
nLight AIR Wireless
nLight AIR is the ideal solution for retrofit or new construction spaces where adding
additional wiring can be labor intensive and costly. The integrated rES 7 smart sensor is
part of each luminaire in the nLight AIR network, which can be grouped to control multiple
luminaires. The granularity of control with the digital PIR occupancy detection and daylight
sensing makes a great solution for any application.

Constant Lumen Management
Enabled by the embedded nLight control, the BLT actively tracks its
run-time and manages its light source such that constant lumen
output is maintained over the system life. Referred to as lumen
management, this feature eliminates the energy waste created by
the traditional practice of over-lighting.

How to Calculate Delivered Lumens in Emergency Mode
Use the formula below to determine the delivered lumens in
emergency mode
Delivered Lumens = 1.25 x P x LPW
P = Ouput power of emergency driver. P = 10W for E10WLCP
option.
LPW = Lumen per watt rating of the luminaire. This information
is available on the ABL luminaire spec sheet. LPW = Lumen
per watt rating of the luminaire. LPW information available in
