Cubito illuminates its square extruded-aluminum profile through two adjacent sides, forming a luminous right angle 2 1/2" on each side, installed either as a discrete luminaire or a seamless continuous line of light. The family is offered as a pendant (Square profile on stem, or Diamond profile on aircraft cable), a drywall mud-flange recessed luminaire, and surface and wall versions with drywall mounting brackets. A single High-Efficiency Lambertian Optic (HLO) distributes the LED output across 0.075" acrylic shielding at up to 88% transmission. Delivered output runs from 275 lm/ft (recessed low output) to 900 lm/ft (pendant ultra high output) with efficacy published up to 144 lm/W; pendant lumen packages are 300/450/700/900 lm/ft and recessed are 275/350/450 lm/ft. Static white is available in 2700/3000/3500/4000/5000K at a minimum 80+ CRI, with an option for 90+ CRI with elevated R9, held to within 3 SDCM; LM-80 testing shows L80 lumen maintenance greater than 60,000 hours. Fixtures ship in 2 ft to 12 ft standard lengths and continuous runs over 12 ft, ordered in 1 ft and 1 in increments and joined onsite with virtually seamless joiner kits. Standard dimming is 0-10V from 100% to 1% on a universal 120-277V driver; the recessed platform adds ELV, TRIAC, DALI, Lutron Hi-lume 1% EcoSystem, and eldoLED 1% ECOdrive / 0.1% SOLOdrive options plus 347V, and the family is PoE compatible. ETL listed to UL 1598 and CSA C22.2 No. 250.0 for indoor dry/damp locations, with optional emergency battery, night-light, and daylight electrical sections, and backed by a five-year limited warranty.
