LR-LB1 Series

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.
