Keystone Traditional Slim LED Wall Pack — 35-55W Selectable, Color Selectable, 120–277V, Bronze

The Keystone KT-WPLED55PS-M4-8CSB-VDIM is a highly adaptable, specification-grade traditional-slim LED wall pack delivering up to 7,645 lumens. Engineered to make LED upgrades effortless, this fixture matches the exact footprint of standard legacy mid-size wall packs—eliminating the need to repaint or patch walls—while offering a modern, 35% slimmer profile. Installers can easily customize the light output by toggling between 35W, 45W, or 55W of power and 3000K, 4000K, or 5000K color temperatures on-site. Operating on a universal 120–277V driver, it includes an integrated dusk-to-dawn photocell for automated security lighting. With its rugged die-cast aluminum housing, borosilicate glass lens, and IP65 Wet Location rating, it is the premier choice for illuminating building perimeters, entryways, and loading docks.

Performance & Light Output

The KT-WPLED55PS-M4-8CSB-VDIM provides powerful, outward-throwing illumination ranging from 4,900 to 7,645 lumens depending on the selected settings. The high-quality borosilicate glass lens casts a wide, uniform pattern to maximize visibility across large perimeters. With an efficacy reaching 145 LPW and a 100,000-hour rated lifespan, this fixture drastically reduces energy consumption and maintenance cycles compared to legacy 250W HID systems.

Electrical & Controls

This fixture operates on a constant current 120–277V AC driver and supports standard 0–10V dimming for integration with advanced lighting controls. The integrated photocell ensures the light only operates when needed, providing reliable dusk-to-dawn automation, but can easily be disabled via a dip switch if the unit is connected to external timers or centralized building systems.

Construction & Durability

Engineered to withstand the elements, the fixture features a heavy-duty die-cast aluminum housing finished in a resilient bronze powder coat. It includes five 1/2-inch threaded conduit hubs for flexible surface-mount wiring. The fixture is impact-rated (IK06) and fully IP65 rated, protecting it against dust and wind-driven rain in extreme temperatures ranging from -40°F to 122°F (-40°C to 50°C).
