Brently is ON LIGHT's 4-inch tubular LED linear lighting fixture (PureTube), an extruded-aluminum and polycarbonate pendant for vertical and horizontal suspended runs. Delivered output runs from 300 lm/ft to 1,500 lm/ft (300, 400, 500, 600, 800, 1,000, 1,200 and 1,500 lm/ft, nominal at 3000K and 80 CRI). White CCTs are 2700K, 3000K, 3500K, 4000K and 5000K plus an RGB option, at 80, 90 or 97 CRI, with delivered-lumen multipliers ranging from 0.53 to 1.0 across CCT/CRI and food-color (bread, meat, fish) renderings. Distributions cover suspended vertical (V), suspended horizontal (H), suspended vertical with a 20° downlight reflector (VS, 1,500 lm) and suspended vertical with a 40° downlight reflector (VW, 1,500 lm), with continuous-row mounting available when suspended horizontally. The 4" (100 mm) diameter tube supports custom lengths up to 12 ft and continuous rows up to 6 tubes / 480 W; a 4 ft section weighs 7 lb (3.5 kg). End caps are offered in matt or gloss white, black and silver plus custom color. Dimming options are 0–10V, DALI, Casambi and on/off on 120V, 277V or 347V input (the aircraft cable is combined inside the power cord for a clean install). Maximum input is 80 W at a 4 ft length and nominal efficacy reaches up to 190 lm/W, with 3-step MacAdam ellipse color consistency. Reported life is 50,000 hours per IESNA TM-21-11 with LM-80 lumen maintenance, photometry conducted by an independent NVLAP-accredited laboratory per IESNA LM-79-08, and the fixture carries a 5-year warranty on the LED light engine, driver and all components; made in Beloeil, Canada.
