LED Troffers for Offices and Suites
Quick answer
A troffer is the rectangular fixture that drops into a ceiling grid. Common sizes are 2x2 and 2x4. LED troffers replace fluorescent troffers and usually add dimming and sensor options.

Troffer choices
You can replace the whole ceiling light, add an upgrade kit, or change only the lamps.
- New troffer: cleanest look, best optics, most cost.
- Retrofit kit: keeps the housing, changes the guts.
- Lamp swap: fastest, lowest cost, old lens stays.
Add controls while the ceiling is open
Motion sensors and daylight dimming cost less when added during an upgrade than as a separate job later.
Common questions
- Will LED troffers look brighter?
- They usually look more even and cleaner. Brightness should be designed to the task, not maximized.
