About this product
Cluster Pi brings the Cluster family's optics and modernist esthetic into a circular fixture that occupies a low profile of under 2" and mounts recessed, surface, or pendant (aircraft-cord, stem, or swivel stem). It is offered in three sizes—Small (3 3/4" dia.), Medium (6 3/4" dia.), and Large (9" dia.)—and three optic systems: the Kinetic Visual Comfort Optic (KVCO), whose concentric prismatic grooves redirect rays to a common focal length for precise, clean beams; the High-Efficiency Lambertian Optic (HLO) with reflective sidewalls and SupremeGrip acrylic shielding for soft diffused light; and the Miniature Reflector Optic (MRO), a molded TIR-plus-parabolic COB system offered in narrow flood (25°), flood (35°), and wide flood (55°) beams with a feathered edge. Delivered output spans 360/400 lm (S), 700/780 lm (M), and 1200/1350 lm (L) for KVCO/HLO, and 890 lm (S), 2100 lm (M), and 2750 lm (L) for MRO. Light source is a 90 CRI array with elevated R9, held within 3 SDCM, in 2700/3000/3500/4000/5000K, with LM-80 L80 lumen maintenance greater than 60,000 hours. Standard dimming is 0–10V to 1% (canopy driver: 0–10V, ELV, TRIAC; remote driver adds Lutron Hi-Lume 1% Eco and Premier 0.1% EcoSystem, DALI, and eldoLED 1% ECOdrive and 0.1% SOLOdrive), with universal 120–277V input and PoE compatibility. Housing is die-cast aluminum with a cold-rolled-steel cover, in textured matte white, matte black, or custom RAL finishes. ETL listed to UL 1598 and CSA C22.2 No. 250.0 for indoor dry/damp locations, and backed by a five-year limited warranty.
