Via Perimeter creates a continuously illuminated "slot" at the wall/ceiling intersection, framing a room in light. It is offered in two apertures — Via 2 Perimeter (2 3/8" wide profile, 350/500/750 lm/ft, up to 108 lm/W) and Via 3 Perimeter (3 1/32" wide profile, 500/750/1000 lm/ft, up to 121 lm/W) — each installing in grid or drywall ceilings in three arrangements: level, shallow (1"), and deep (3 1/4"). The Via 2 offers High-Efficiency Lambertian (HLO) and Micro-Prismatic (MPO, UGR<17) optics; Via 3 adds an Asymmetric Room Fill Optic (ARFO, not available on Deep). Lighted corners are achievable with the optional adjustable end sleeve (TES), which provides +2.5" to -4.5" of on-site length adjustment for clean wall-to-wall runs. LEDs ship in 2700/3000/3500/4000/5000K at a minimum 80 CRI (optional 90 CRI with elevated R9), held to 3 SDCM. Standard sections run 2 to 12 ft (up to 8 ft for MPO) and join into seamless continuous runs (2 ft minimum section) with field-installed joiner kits. A factory-set, adjustable-output driver takes universal 120–277V (347V optional) input and dims 100–1% on 0–10V, with ELV, TRIAC, DALI, Lutron Hi-lume 1% EcoSystem, and eldoLED 1% ECOdrive / 0.1% SOLOdrive options; it is PoE compatible and the driver rated life is 50,000 hours (90% survivorship) at 50 °C ambient. Integrated onboard daylight (ODS) sensors and connected-controls nodes (Lutron, Encelium, Cooper WaveLinx, Acuity nLight, Casambi, Legrand) are available. Via Perimeter recesses into exposed or concealed T-bar and tegular grid (9/16" and 15/16") or drywall with trim, trimless, or mud-flange details, is IC rated for direct contact with insulation, and is TechZone and USG compatible with a 4" ceiling. ETL listed to UL 1598 and CSA C22.2 No. 250.0 for indoor dry/damp locations, Chicago Plenum approved (CCEA) with the CP option, LBC Red List Declare approved, and backed by a five-year limited warranty.
