Cooper Lighting Envoy Double-T Structural Ceiling, direction generally offers the best solution

DOUBLE-T STRUCTURAL CEILING

In typical double-T structural ceiling designs, the luminaire is placed between 2 beams that are no more than 4 feet apart. In a surface mount

scenario this method traps a significant amount of light within the ceiling structure, leading to compromised light levels on the work plane.

When designing for T structure ceilings, the optimal

solution is to mount the fixture via pendant pipe at or

below the bottom plane of the beam level. Since beams

typically traverse laterally along the width of the garage,

using the rectangular [TG] distribution in the same

direction generally offers the best solution.

PENDANT MOUNT APPLICATIONS

Garage fixtures are commonly mounted to pendant pipes to bring the light source closer to ground level to achieve increased light levels. Many times

this is desirable due to higher ceiling heights or structural supports at the ceiling level that interfere and block light emitted from the luminaire. Envoy

offers multiple pendant mount solutions. When a bird nesting deterrent is required in pendant applications, use the [PBG] accessory.

FREE SWING PENDANT + PBG

ACCESSORY [OFFSET POSITION] Envoy is attached to the pendant box [PBG] accessory using the standard quick mount release bracket system. The pendant conduit pipe and free swing swivel hanger system are provided by others. Because the system is free swinging, the offset pipe position must be used to allow the fixture to hang straight.

RIGID PENDANT + PBG ACCESSORY

[CENTER or OFFSET POSITION]

Envoy is attached to the pendant box [PBG] accessory using the standard quick mount release bracket system. The pendant conduit pipe and suspension mechanism are provided by others. Because the system is rigid and non-moving, the center or offset pipe position may be used to hang the fixture.

RIGID PENDANT + J-BOX

[CENTER POSITION]

Envoy is attached to a 4" junction box using the standard quick mount release bracket system. The pendant conduit pipe and junction box with center pendant entry access are provided by others. The center position of the J-Box may be used to hang the fixture.
