IP65
To avoid the risk of fire, explosion, or electric shock, this product should be installed,
inspected, and maintained by a qualified electrician only in accordance with all
applicable electrical codes.
To avoid electric shock:
• Be certain electrical power is OFF before and during installation and maintenance.
• Luminaire must be connected to a wiring system with an equipment-grounding
conductor.
• Make sure the supply voltage is the same as the rated luminaire voltage.
• Do not operate in ambient temperatures above those indicated on the luminaire
nameplate.
• No user serviceable parts inside of fixture. Removal of lens will void the warranty.

Design
When designing a layout for a particular application, there are several factors that should be taken into
consideration.
The typical mounting height for model LR-LB1 is 8 - 24 ft. from the ground. This mounting height is a
recommendation only. The facility usage purpose, colour scheme, desired brightness levels, and overall
facility size will all factor into the layout of the lighting fixtures.
These LED Lighting Fixtures are NEC Class 1 compliant. Check applicable province, local, and national
codes before designing and installing lighting fixtures.
A common misconception with LED lighting is the belief that they do not generate heat. While it is true
that LED fixtures produce much less heat than other forms of lighting due to the increased efficiency and
lower power consumption, thermal management is still a crucial component of a well-designed LED
fixture. The LR-LB1 fixtures have been designed to not only enclose the LEDs and circuitry, but to act as
a heat sink as well. These fixtures utilize state of the art thermal interface materials to conduct the heat
from the LED module to the housing. The housing has been geometrically designed with a large surface
area for excellent convection of heat away from the housing. As a result, the LR-LB1 series fixture is
warranted for 50,000 hours of use within an ambient temperature of up to 45°C (113°F). For maximum
long-term reliability, this light should be installed in free air.

IP Code Definition and Explanation of IP65 Rating
The IP Code, International Protection Marking, IEC standard 60529, also interpreted as Ingress Protection
Marking, classifies and rates the degree of protection provided against intrusion (body parts such as
hands and fingers), dust, accidental contact, and water by mechanical casings and electrical enclosures.
Solid Particle Protection: The first digit indicates the level of protection that the enclosure provides
against access to hazardous parts (e.g., electrical conductors, moving parts) and the ingress of solid
foreign objects. 6: Totally protected against dust ingress.
Liquid Ingress Protection: The second digit indicates the level of protection that the enclosure provides
against harmful ingress of water. 5: Protected against low pressure jets of water from all directions - limited
ingress

3.0 Maintenance, Care, and Usage
Visual, mechanical, and electrical inspections should be performed on a regular basis. Routine checks at
least once a year are recommended. Frequency of use and environmental conditions may make it necessary
to perform more than one routine check per year. It is recommended to follow the Electrical Preventative
Maintenance Program as described in NFPA 70B: Recommended Practice of Electrical Equipment.
The lens should be cleaned periodically as needed to ensure continued photo-metric performance. Clean
the lens with a damp, non-abrasive, lint-free cloth. If a damp cloth alone is not sufficient, use mild soap or
a liquid cleaner. Do not use an abrasive, strong alkaline or acid cleaner as damage may occur.
Inspect the cooling fins on the luminaire to ensure that they are free of any obstructions or contamination
(i.e. excessive dust build-up). Clean with a non-abrasive cloth if needed.
Electrical connections and wires should be checked for exposed wire and overall circuit integrity.
Bracket Mount Installation
NOTE: Accessory installation sheets supersede these instructions.
1 Sub assemble the eyebolt to the hanging bracket using the two jam nuts and one lock washer
(provided) in a sandwich-like assembly.
2 Use the four screws provided on the main housing to attach the hanging bracket assembly to the
housing.
3 Use a chain or cable (must be able to bare the weight of 50 lbs. or more) and hook into the eyebolt.
Always close “S” hooks if used.

4.0 Electrical and Wiring
General Wiring Steps
The LR-LB1 Series of LED Fixtures is an AC driverless bay light. We have eliminated the ballast component
of the light which, in a conventional LED fixture, transforms the mains voltage to DC and steps the voltage
down to the level required by the LED module. The ballast and LED module in a standard fixture are often
not compatible with the existing building management systems as the ballast has specific power
requirements in order to supply the LED module with the correct DC voltage and amperage. The LR-LB1
Series, on the other hand, is exceptionally versatile due to the advanced circuitry employed in the
construction of the AC driverless LED module. This facilitates straightforward integration of controls such
as daylight harvesting, occupancy sensors, timers, and dimmers. Essentially, from a control aspect, the
LR-LB1 Series behaves similarly to an incandescent light bulb.
When installing the LR-LB1 Series LED Lighting Fixtures, it is important to be aware of, and comply with,
all province, local, and national codes applicable to LED lighting and other Class 1 compliant lighting
fixtures before beginning installation.
If the fixture is to be hard-wired into a junction box, determine the required lumen level by referring to the
Specifications table on page 4 as well as the Wiring Diagrams on page 9. Required wiring will vary
depending on the lumen level to be achieved. This fixture is designed for 120VAC, single phase only.
Dimming
The LR-LB1 Series is capable of dimming from 10% to 100%. The lifespan of the LED is not diminished
when using a control system for dimming. Phase-cut dimmers, particularly forward phase/ leading-edge
are compatible with the LR-LB1 AC driverless technology. Other types of dimmers may or may not be
compatible, depending upon manufacturer and specific application.
Additional Power Saving Options
The LR-LB1 fixture has been designed with a modular LED circuit board which allows the maximum
power consumption to be hardwire limited to 1/3 or 2/3rds the maximum output. There are often areas
of a facility which do not require the full amount of illuminance due to different light requirements for
different tasks, but similarly, it makes economic sense to install the same light fixture throughout the
facility. In addition to being individual controllability, the LR-LB1 can be switched from 1/3, to full power
by a switch on a panel, or through an occupancy sensor. By hardwire limiting the output of the fixture,
many lights can be in a zone of control, operated by a single sensor, and result in varying amounts of
illuminance from the exact same fixture depending on mounting heights, and specific task requirements.
