Sienna 1.5 Micro Cavity Optic pairs the one-and-a-half-inch Sienna pendant profile with recessed round micro-cavity cells (black or white, direct only) for glare control - Picasso publishes UGR under 16 for the 1 and 1.5 MCO versions. The extruded-aluminum housing with integral driver comes in nominal 2, 4, 6, and 8 ft lengths (custom in 6.5 in increments) and can be continuously rowed. Direct output is selectable from 350 to 1000 lm/ft in 25-, 35-, or 45-degree beams, with optional 350 to 1000 lm/ft indirect via Lambertian, 120-degree batwing, flat 150-degree, or asymmetric uplight optics; the performance table lists 9 W/ft at 750 lm/ft direct (82 lm/W) and 7 W/ft at 1000 lm/ft indirect (150 lm/W) at 3500K. CCT options are 2700K-4000K (tunable white and warm dim available on request) in 80+ or 90+ CRI, with 0-10V 1% dimming standard at universal 110-277 VAC and non-dim, Lutron EcoSystem 1%, and custom controls offered. The Sienna series is also available in wall, surface, surface-grid, and recessed versions. IBEW-manufactured in the USA, UL listed for dry and damp locations, 50,000-hour rated LEDs, limited five-year warranty.
