The UpgradeToLED 4FT Black Architectural LED Linear Light is a premium commercial lighting fixture designed to deliver elegant direct and indirect illumination for modern offices, educational facilities, hospitality spaces, and architectural interiors. Featuring a sleek black aluminum housing and seamless continuous-run capability, this fixture combines sophisticated aesthetics with exceptional lighting performance.
Designed with field-adjustable uplight and downlight distribution, the fixture allows installers to select five lighting configurations, including 100% uplight, 70/30, 50/50, 30/70, and 100% downlight, making it easy to customize illumination for any commercial environment. Independent 3CCT selectable controls allow both the uplight and downlight to be adjusted between 3500K, 4000K, and 5000K to achieve the ideal lighting atmosphere.
Delivering 50 watts of total power with an efficacy of 115 lumens per watt, the fixture provides bright, uniform illumination while minimizing energy consumption. Operating on 120-277VAC (optional 277-347VAC available), it features smooth 0-10V dimming and supports optional occupancy motion sensors and emergency battery backup for enhanced energy savings and code compliance.
Installation is flexible with pendant, surface, recessed, and wall mounting options. The innovative end-cap design enables seamless continuous runs using straight, L, T, and cross connectors, creating uninterrupted lighting patterns ideal for open offices, conference rooms, lobbies, retail environments, hospitality spaces, and commercial interiors.
