Commercial Indoor Lighting by Fixture Family
Residential lighting sites organize by room and style. Commercial projects do not work that way: a specifier starts from the space type, the ceiling, and the light level the work requires, then lands on a fixture family. This page is the map. Each family below carries a working lumen range, its typical mounting, and the spaces it usually serves, with the full catalog one click away.
| Fixture Family | Typical Lumen Range | Mounting | Typical Spaces |
|---|
| High Bay Lighting | 10,000 to 45,000 lm | Hook, cable, or grid at 15 ft and up | Warehouses, manufacturing, gyms |
| Recessed Lighting | 3,000 to 6,000 lm per troffer; 600 to 3,000 lm per downlight | Lay-in grid or drywall recess | Offices, schools, healthcare, retail |
| Surface Mount Ceiling Lights | 1,500 to 10,000 lm | Direct to ceiling, no plenum needed | Corridors, stairwells, utility rooms |
| Pendant Lights | 1,000 to 15,000 lm | Suspended by stem or aircraft cable | Open offices, lobbies, dining |
| Wall Mounted Lights | 500 to 5,000 lm | Wall bracket or sconce backplate | Stairwells, patient rooms, corridors |
| Task & Accent Lighting | 100 to 600 lm per ft (linear formats) | Under cabinet, in cove, on track | Workstations, displays, millwork |
| Exit and Emergency Lighting | Code-driven output | Wall, ceiling, or end mount | Every occupied commercial building |
| Retrofit Kits | Matches host fixture | Installs into existing troffers, strips, and cans | Large-scale LED conversions |
| Specialty Lighting | Application-specific | Varies | Clean rooms, docks, hazardous locations |
The Three Spec Filters That Matter
Three listings and options come up on nearly every commercial fixture cut sheet, and they decide more purchasing outcomes than style ever does.
- CCT-selectable: a switch on the fixture selects the color temperature, typically 3500K, 4000K, and 5000K. One SKU covers an office floor and a warehouse, which simplifies ordering and spares on multi-space projects.
- 0-10V dimming: the standard commercial dimming interface. Two low-voltage control wires let occupancy sensors, daylight harvesting, and building controls dim the fixture. If a control system is anywhere in the project's future, specify it now.
- DLC listing: the qualification most utility rebate programs require, with DLC Premium as the tier for the best incentive rates. Product pages here carry the listing number a contractor or ESCO needs for the rebate application.
Lumens vs Watts, in One Paragraph
Watts measure what a fixture consumes; lumens measure what it delivers. LED broke the old habit of shopping by wattage, because two 40W fixtures can differ by thousands of lumens depending on efficacy. Compare fixtures on delivered lumens and lumens per watt, then check the photometric file for how that output distributes across the space. Spec sheets and IES files on individual product pages support the lighting calculations behind a submittal package.
Where to Start by Project Type
Warehouse and industrial retrofits start in high bay lighting, where DLC Premium fixtures at 100W to 320W replace metal halide one for one. Office and school buildouts start with troffers and panels in the recessed family, with surface mount fixtures handling the hard-ceiling corridors between them. If the building already has fluorescent fixtures worth keeping, retrofit kits convert troffers, strips, and cans to LED at a fraction of the labor of full replacement. Bulk pricing and project quotes are available on qualifying orders across every family in this catalog.
