LED Flexibility and Modular Design

Type I - Long and narrow

distribution pattern designed
with walkways in mind.

Choose from three color temperatures (CCT): 3000K, 4000K, and 5000K

Four light distribution patterns: Type I, Type III, Type V and Type V wide for application flexibility.
Seven mounting hoods allow one fixture to be configured for ceiling, pendant, stanchion, or wall applications.
Three globes; clear and diffused polycarbonate and clear glass globe provide just the right level of diffusion.

Safety Features Type I & Type III Hinge System

Type III - Wall mounted

distribution pattern designed
where you need good forward
light projection.

Type V - Symmetrical circle
distribution pattern ideal when
you need even coverage in all
directions.

Type V Wide - Like the Type V
distribution pattern with more
vertical lumens designed to help
spread the light quicker and

Simple quick disconnect
connector disconnects
power between LEDs
and battery management
module to allow
maintenance in hazardous
locations.

New watertight pendant
hood provides protection
against water ingress in
the conduit utilizing an
IP68 cord grip with 3 wire
holes 4 mm in diameter.

Safety cable is slipped
around the housing
through retention points
that are casted in. Safety
cable has built in loops
combined with a locking
carabiner to allow for
a quick and secure
installation.

Easy field changeable
duration setting between
