Application guidance for commercial office, healthcare, K-12 and higher-education classrooms, retail, hospitality, distribution and warehouse, parking-structure, sports field, roadway, and Class I Division hazardous lighting programs across both new construction and retrofit scopes.
From Class I Division 2 hazardous refineries running Holophane Predator high-bays to K-12 classroom retrofits using Lithonia VTLED tunable-white troffers tuned across 2700K through 6500K, application engineers maintain reference designs covering office, healthcare, retail, hospitality, warehouse, parking-structure, sports field, and roadway scopes that respect both ANSI/IES RP-1 visual targets and the local energy code.
Industry Cards / image cards three column
Reference designs map RP-1 office targets at 30-40 maintained footcandles to BLT-LP and 2BLT troffers, RP-7 industrial high-bay targets at 50 fc onto Holophane Predator and IBG round high-bays, and RP-20 parking-structure photometrics to Lithonia D-Series area lights with Type II, III, and IV optical distributions, while educational scopes lean on VTLED tunable white at 0.5-step dimming for circadian schedules.
2x2 BLT-LP troffers at 35 lm/W delivered through batwing optics provide 30 maintained footcandles with UGR<19 ratings across open-plan benches, hot-desk neighborhoods, and conference Type-22 layouts, paired with 0-10V dimming for personal control overrides at every workstation cluster.
IBG round high-bays mounted at 28 ft project 30 footcandles on rack tops with five-degree narrow optics, 110 lm/W efficacy under ambient 40 C, and integrated nLight aisle occupancy sensors that drop unoccupied lanes to 10 percent within thirty seconds.
nCom downlights and Mark Architectural patient-room linear products blend exam-mode 5000K daylight tones with night-mode 2700K warm tones via DALI-2 dimming down to 0.1 percent output, supporting circadian schedules tuned through the headwall control panel.
D-Series Size 1 and Size 2 area lights with Type II, III, and IV optics meet RP-8 luminance and uniformity ratios for collector roads and parking lots at 25 ft pole heights, 4000K CCT, and ANSI C136.41 dimming receptacles for photocell control.
Project Stats / counter bar
Across the last fiscal year regional teams supported more than 18,000 specification packages, including 4,200 K-12 classroom retrofits, 2,600 corporate office buildouts, 1,900 healthcare clinical refreshes, 3,400 industrial DC and warehouse projects, and a growing roster of stadium, university campus, and Class I Division 1 hazardous-area programs that require BAA-compliant sourcing, with average delivery from PO to staging warehouse holding under six weeks.
Annual fixture and controls submittal packages issued through regional sales agents, direct national-account engineering teams, and the federal-channel desk supporting GSA, VA, and Department of Defense projects across the continental United States and Hawaii.
K-12 classroom retrofits using VTLED tunable-white troffers and Mark Architectural pendants aligned to circadian schedules, ASHRAE 90.1 daylight-zone requirements, and CHPS Collaborative for High Performance Schools visual-comfort guidance for elementary and secondary classroom programs.
Industrial high-bay projects spanning grocery cold storage, e-commerce sortation, parcel hubs, and bulk warehousing with networked nLight aisle control, motion-driven dimming, and integrated emergency egress packs sized for the local NFPA 101 path-of-egress lumen targets.
Buy America Act-compliant SKUs are maintained across the troffer, downlight, area, high-bay, and emergency-exit categories for federal building scopes, with documented domestic content percentages filed against the most recent Build America Buy America rule update.

Share the building program, ceiling type, and target energy code envelope and a sector-specific applications engineer will return a tailored fixture and controls schedule, citing the relevant ANSI/IES recommended practice document, the DLC Premium SKU choice, the Title 24 Section 130.1 compliance path, and a phasing plan that keeps occupied spaces lit during change-out windows.
