100W Low Profile Explosion Proof LED Light
2x4 Lay-In Troffer Class 1/2 Div 1/2 Paint Spray Booth
Instruction Manual
This explosion proof 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 design focuses the light 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 single phase power supply within voltage marked on nameplate without any variation in light
output.
WARNING
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.
To avoid explosion:
•Make sure the supply voltage is within the luminaires’ voltage rating.
•Ensure the marked T rating is less than the ignition temperature of the Hazardous
Atmosphere.
•Do not operate in ambient temperatures above those indicated on the luminaire nameplate.
•Do not operate if the lens is cracked or damaged. All fasteners should be properly seated.
For supply connections, use wire rated for at least 110°C
Recommended mounting height is 25-40 feet.

This unit comes preconfigured with cord whip, selected voltage, beam angle, and color temp. Once
mounted, plug cord into compatible receptacle with correct voltage. Check nameplate for proper
voltage.
MAINTENANCE
Caution: 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. Perform visual, mechanical and electrical inspections on a regular basis. We recommend
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. The lens should be cleaned periodically as needed to ensure continued photometric
performance. Clean the lens with a damp, non-abrasive, lint-free cloth. If not sufficient, use
mild soap or a liquid cleaner.
3. Inspect the cooking 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.
4. Do not operate if the lens is cracked or damaged. All fasteners should be properly seated.
