Alcove Ramp is Lumenwerx's turnkey version of the Alcove cove luminaire: the same compact 1 13/16" high by 3 7/8" deep LED luminaire supplied inside its own attractive sloped enclosure, eliminating the need to build a site cove. The ramp fascia is offered at a 90º or 35º angle, mounts a bracket directly to the wall, and extends 8 1/2" from the wall at 2 5/8" high; a gypsum-board bottom panel finishes the housing. Light comes from the Asymmetric Projecting Optic (APO) — cartridge-mounted linear LED arrays paired with specular and matte-white reflectors behind a clear acrylic cover — angled to produce peak intensity at 110º above nadir with an 11.8:1 peak-to-zenith ratio and 80º field coverage. Cartridges rotate upward on site in 5º click-stops across 13 discrete aiming angles to raise vertical projection, so a single run can be tuned to the ceiling. Delivered output spans five packages — eco low, low, medium, high, and ultra high — measured per 4 ft at 1400, 2200, 3000, 3800, and 4800 nominal delivered lumens (350, 550, 750, 950, and 1200 lm/ft) with efficacy up to 134 LPW. LEDs are offered at 2700K, 3000K, 3500K, and 4000K with a minimum 80 CRI or an optional 90 CRI with elevated R9, held within 3 SDCM, and tested to IESNA LM-80 showing L80 lumen maintenance beyond 60,000 hours. The universal-input (120–277V, 347V optional) driver dims 100% to 1% on 0–10V, with Lutron Hi-Lume 1% Eco Dim-to-Off and DALI options and factory emergency battery, emergency-circuit, night-light, and generator-transfer add-ons. Individual luminaires reach 12 ft; continuous runs join 8 ft maximum modules with quick-connects, and driver and LED boards service without removing the luminaire. ETL listed to UL 1598 and CSA C22.2 No. 250.0 for indoor dry/damp locations, backed by a five-year limited warranty.
