Luminaire

Cable Mounting Kit
Suspension is convenient
and flexible with the SS
Aircraft Cable “Y” Toggle
Mounting Kits. Adjustment
for luminaire mounting height
is provided at luminaire
rather than structure.
Occupancy Sensor
Integral occupancy
sensor available and
provides from 600
sq. ft. up to 1250 sq.

Micro-Bay luminaire
The MB series (Micro-Bay) is a functional and multi-purpose low profile fluorescent high bay that incorporates
premium performance and durable construction. Designed for T5 and T8 fluorescent technology, the MB series
offers both high performance and application versatility.
Micro-Bay is designed for narrow or medium distributions in high mounting applications.
Row mounting of the Micro-bay is easily accomplished with an external rigid section connector that provides
excellent row alignment through the entire length of the row. Suspension is convenient and flexible with the SS
Aircraft Cable “Y” Toggle Mounting Kits. Adjustment for luminaire mounting height is provided at luminaire rather
than structure height.
Energy Savings – Up to 70% energy reduction for comparable light levels.
Superior Lumen Maintenance and Longer Lamp Life – Rated at 25,000+ hours based on 10 hour starts.
Improved Color Rendering – Improves visual acuity for a more pleasant work environment.
Instant Ignition – Easy and inexpensive integration with emergency lighting requirements.
Increased Energy Savings – Programmed Rapid Start ballasts and pre-wired configuration allow for utilization
of Occupancy Sensors with Photo Control ability, further reducing energy consumption.

System Performance
The Micro-Bay series delivers high performance in a streamlined package. The Micro-Bay’s large assortment of
optical distributions meet a wide range of mounting heights and aisle configurations – providing unmatched uniformity
performance. The Micro-Bay is the solution to improving visibility while delivering the lowest watts/sq. ft.
Plug-In Connectors
Optional pre-wired factory installed
multiple circuit plug-in connectors.

Rigid Exterior Connector
Rigid exterior connector/coupling
with pre-punched holes facilitates
easy installation of coupled
sections up to 32' long.

Catalog Numbering System
The PI System is available in sections up to 8' in length for continuous row wiring by simply plugging the
sections together. Each PI section is factory wired to the ballast leads. Color coding of wires is as follows:
PI-1 = One Circuit - 2 Wires: one black, one white
PI-2 =Two Circuits - 3 Wires: one black, one blue, one white
PI-3 =Three Circuits - 4 wires: one black, one blue, one red, one white
When ordering the PI2/PI3 System it is necessary to specify the number of fixtures required for each circuit.
Each circuit in fixture must be ordered as a separate line item, with a different hot wire color specified.
All wiring to external feeds, using cord or cord & plug, are responsibility of installing licensed contractor. Cord
and cord & plug sets must be ordered separately if PI option is chosen.
