Troffer Series
Efficient illumination. Built for professional spaces.
Versatile LED troffer solutions engineered for uniform commercial illumination, flexible performance and intelligent occupancy control.
Overview
A recessed troffer platform for professional interiors
The Troffer Series is a commercial ceiling-lighting platform built for professional and institutional interiors. Its recessed troffer form drops into standard grid ceilings and delivers uniform, glare-controlled illumination for offices, classrooms, healthcare and commercial spaces.
Field-selectable wattage and 5CCT selectable color let a single fixture meet a wide range of specifications, while 0-10V dimming, emergency-backup readiness and a recessed PIR Sensor-Ready base support energy codes and occupancy control.
- Up to 150 lm/W efficacy
- 5-year limited warranty
- 120-277V universal voltage
Key Features
Uniform recessed light with flexible control
Every Troffer combines selectable output, tunable color and control-ready options in a recessed grid-ceiling fixture. The Troffer Series reaches up to 6,000 lm at up to 150 lm/W.
Selectable Wattage
Field-selectable multi-wattage lets one troffer meet multiple power requirements on site.
5CCT Selectable
Choose 3000K, 3500K, 4000K, 5000K or 6500K directly at the fixture.
Sensor-Ready
Recessed PIR sensor base provides occupancy-control capability.
Emergency Backup Ready
Emergency-backup ready to support egress lighting requirements.
0-10V Dimming
Smooth, continuous 0-10V dimming for control systems and energy savings.
120-277V Universal
Universal 120-277V input with up to 150 lm/W efficacy for broad commercial use.
Sensor-Ready Control
Built-in occupancy control
The entire Troffer family is Sensor-Ready. A recessed PIR sensor base integrates into the end cap for occupancy-based control, using the same Sensor-Ready design language found across the Corso range.
Recessed PIR Sensor Base
A recessed PIR sensor base sits in the end cap, keeping the sensor flush and unobtrusive within the fixture.
- Integrated into the end cap
- Flush, recessed profile
Occupancy Control
Occupancy-based control pairs with 0-10V dimming to reduce energy use in intermittently occupied spaces.
- Occupancy-based switching
- Works with 0-10V dimming
