lithonia WST Specifications

FEATURES & SPECIFICATIONS

INTENDED USE— For building- and wall-mounted applications.

CONSTRUCTION — Rugged, die-cast, single-piece aluminum housing. Die-cast door

frame has a 1/8” thick tempered glass lens. Door frame is fully gasketed with one-piece
solid silicone.

FINISH — Standard finish is textured dark bronze (DDBT) corrosion-resistant polyester
powder finish.Additional architectural colors are available; see www.lithonia.com/
archcolors. Striping is also available.

OPTICAL SYSTEM — Segmented reflectors for superior uniformity and control. Reflec­tors are interchangeable. Three full cutoff distributions available: FT (forward throw),
MD (medium throw) and WT (wide throw).

ELECTRICAL SYSTEM — Ballast: 50W-150W utilizes a high reactance, high power factor
ballast. Metal halide 150W and below are standard with pulse-start technology. 35S
utilizes a reactance high power factor ballast. 175W utilizes a constant-wattage au­totransformer ballast. Quick disconnect plug easily disconnects reflector from ballast.
Ballasts are copper-wound and 100% factory-tested. CSA, NOM or INTL required for
probe start shipments outside of the US for 175M. Not available 175M SCWA. Ceramic
metal halide lamps are recommended for use in applications where superior color
rendition, lumen maintenance and longer lamp life are desired.

Socket: Porcelain, medium-base socket with copper alloy, nickel-plated screw shell and
center contact. UL listed 660W, 600V 4KV pulse rated.

INSTALLATION — Universal mounting mechanism with integral mounting support allows
fixture to hinge down. Bubble level provides correct alignment with each installation.

LISTING — UL Listed (standard). CSA Certified (see Options). Suitable for wet locations
(damp location listed in lens-up orientation). WLU option offers wet location listing in up
orientation (see Options). IP65 rated. 25°C ambient
