Acuity Brands engineers commercial luminaires and integrated controls under one roof, from Lithonia troffers to Holophane high-bays, Gotham downlights, Mark Architectural linears, Peerless suspended fixtures, and nLight networked sensors with Atrius IoT data services running on top of the installed base.
Headquartered in Atlanta with manufacturing across Conyers, Crawfordsville, and Monterrey, the portfolio covers indoor LED fixtures from 2x2 troffers at 90 lm/W up through 30,000 lm linear high-bays, plus outdoor area, emergency egress, and DLC Premium qualified products engineered to ASHRAE 90.1 and California Title 24 envelopes that specifiers can submit without redlining a single IES file.
Company Facts / data grid two column
Operating at industrial scale since the 2001 spin-off from National Service Industries, the company ships roughly four million luminaires a quarter through Lithonia Lighting, Holophane, Peerless, Mark Architectural, Gotham, A-Light, Eureka, and Winona, plus the Acuity Distech building-management line and the Atrius IoT data platform. Engineering centers in Conyers run photometric labs that measure UGR, BUG ratings, and TM-30 fidelity for every luminaire family before it hits the spec sheet.
Type C goniometers in Conyers and Decatur produce IES files that match field-measured footcandles within 5 percent across 2700K, 3500K, 4000K, and 5000K SKUs, with TM-30 fidelity and gamut indices reported alongside CRI for color-critical retail and gallery scopes.
Driver, optic, and housing tooling lives inside Acuity facilities, so 0-10V analog dimming, DALI-2 digital addressing, and nLight Air radio variants of the same fixture family share one bill of materials and one continuous warranty path.
UL 1598 wet-location ratings, UL 924 emergency listings, DLC Premium 5.1 qualifications, California Title 24 JA8 entries, and Buy America Act sourcing data are all maintained by a dedicated in-house compliance group reporting to the chief technology officer.
Field application engineers walk integrators through nLight gateway addressing, sensor profile loading, scene programming, daylight calibration, demand-response signal mapping, and Atrius location services before owner sign-off and the building turnover punch list.
Certifications / simple list
Listings stay current because product engineering and certification labs share the same agile cycle: every luminaire family is filed against UL 1598, UL 924 for emergency egress, UL 8750 for LED equipment, and CSA C22.2 No. 250 before its first DLC Premium submission, with IP65 and IP66 wet-location ratings independently verified for outdoor area, wall-pack, and parking-structure SKUs. Title 20 appliance efficiency and Title 24 Section 130.1 compliance is checked against the latest CEC database revision before any spec sheet ships to a California project.
Qualified across troffers, high-bays, downlights, and outdoor area lights at delivered efficacies between 130 and 165 lm/W, with LM-80 driven L70 lifetimes documented to 100,000 hours of operation under typical commercial duty cycles.
Self-test self-diagnostic emergency drivers, integrated battery packs, and Lithonia ELM exit sign families carry the full 90-minute battery backup window verified annually per NFPA 101 Life Safety Code means-of-egress requirements and field maintenance protocols.
Outdoor area, parking flood, and hazardous Holophane Predator and Prismalume housings hold sealed silicone gaskets through 1,000-hour ASTM B117 salt-spray exposure, IK08 impact tests, and continuous wet-rated operation in coastal and chemical environments.
nLight Air radio modules and xPoint Wireless gateways operate in the 2.4 GHz ISM band under FCC Part 15.247 unlicensed authorization, with Industry Canada RSS-247 equivalents and CE RED listings filed for international project shipments.
