1: Introduction
This Linear LED light is designed for illumination of industrial locations. It uses the latest in solid state
lighting technology for long life, low maintenance, and high efficiency.
The unique optical design focuses light downward to where it is needed, giving improved efficiency over
a conventional HID luminaire.
An internal, universal input, power-factor-corrected switch-mode supply allows it to be used from any
nominal 100V-277V, 50/60Hz AC supply without any variation in light output.
Models listed above are SUITABLE FOR WET LOCATIONS in unclassified locations:
Temperature Code: T5 for 2' model, T5 for 4' model
Ambient Temperature Range: -40C to +65C
Note: Save these instructions for future reference.

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.
Warning:
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.
Warning:
•DO NOT let power cord touch hot surfaces
•DO NOT mount near gas or electric heaters
•Equipment should be mounted in locations and at heights where it will not be subjected to
tampering by unauthorized personnel.
•The use of accessory equipment not recommend by the manufacture may cause an unsafe
condition
•DO NOT use this equipment for other than it’s intended use
Warning:
The technical data indicated on the Luminaire are to be observed.

Conduit thru Mount (Figure 2) Installation Steps:
•For maximum long term reliability and light output, the light must be installed in free air.
oThe Linear fixture design incorporates an over-temperature control circuit that reduces
input power should internal temperatures reach a maximum level. In this event, light
output may be reduced.
•The Linear fixture is threaded for two 3/4” NPT, at each end, of the Power Supply Housing’s
Junction Box Sections, in order to be assembled to conduit or with cable.
oRemove the 3/4 NPT pipe plugs and attach conduit or cord grips where shown in figure
2. Use conductive pipe sealant for all metal fittings and conduit. Use Teflon tape for
polycarbonate 3/4 NPT pipe plugs.
o Warning: If there is moisture present, or chance of it, in the conduit system then
necessary precautions should be taken by the installer to prevent the moisture from
entering thru the cable or conduit and entering the fixture. Failure to comply with the
above could void factory warranties.
oFixture is factory wired with LINE, NEUTRAL and GROUND leads at each end. Remove the
Power Supply Junction Box Cover, which has captive screws, to attach incoming power to
the white (Neutral) wire, black (Line) and green (Ground) wire leads with Lever Connectors.
Ensure that the o-ring is properly seated in the groove; reattach the Cover. Tighten all
screws to 15 in/lbs (1.75NewtonM’s)
oRestore power and verify operation.

3: Maintenance
•To avoid personal injury, disconnect power to the light and allow the unit to cool down before
performing maintenance.
Warning: No user serviceable parts inside of fixture. Risk of electric shock. Removal of the lens
will void the warranty.
1) We suggest performing visual, mechanical and electrical inspections on a regular basis. We
suggest routine checks to be made on a yearly basis. Frequency of use and environment
should determine this. It is recommended to follow an Electrical Preventive Maintenance
Program as described in NFPA 70B: Recommended Practice for Electrical Equipment.
2) If the lens (Figure 4 below) requires periodical cleaning to ensure continued photometric
performance. Clean the lens with a damp, non-abrasive, lint-free cloth. If not sufficient, use mild
soap and water.
3) Inspect the outside of the Luminaire housing 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.
4) Do not operate if the lens is cracked or damaged. All fasteners should be properly seated.
5) NOTE: Screws, other than the Junction Box area, are factory torqued and should not be
tampered with during installation or maintenance.
