FEATURES & SPECIFICATIONS
INTENDED USE
The energy savings, long life and easy-to-install design of the TWH LED make it the smart choice for
building-mounted doorway and pathway illumination for nearly any facility.
CONSTRUCTION
Die-cast aluminum housing has an impact-resistant, tempered glass lens that is fully gasketed.
Modular design allows for ease of maintenance. The LED driver is mounted to the front casting to
thermally isolate it from the light engine for low operating temperature and long life. Housing is
completely sealed against moisture and environmental contaminants.
FINISH
Exterior parts are protected by a zinc-infused Super Durable TGIC thermoset powder coat finish
that provides superior resistance to corrosion and weathering. A tightly controlled multi-stage
process ensures a minimum 3 mils thickness for a finish that can withstand extreme climate
changes without cracking or peeling. Available in textured and non-textured finishes.
OPTICS
Protective glass lens covers the light engine’s precision-molded proprietary acrylic lenses. Light
engines are available in 3000K, 4000K and 5000K configurations.
ELECTRICAL
Light engine(s) consist of 72 high-efficacy LEDs mounted to a metal-core circuit board and integral
aluminum heat sink to maximize heat dissipation and promote long life (L93/100,000 hrs at 25°C).
The electronic driver has a power factor of >90%, THD <20%, and a minimum 6 KV surge rating.
When ordering the SPD option, a separate surge protection device is installed within the luminaire
which meets a minimum Category C low operation (per ANSI/IEEE C62.41.2).
INSTALLATION
Back housing is separated from front housing, eliminating ballast weight and promoting easy
handling. Top 3/4” threaded wiring access. Back access through removable 3/4” knockout.
Feed-thru wiring can be achieved by using a condulet tee. Mount on any vertical surface.
Not recommended in applications where a sprayed stream of water can come in direct
contact with glass lens.
