Troffer lighting (aka recessed troffer lighting) is a term that is often used to describe indoor lighting fixtures that are mounted within a ceiling or ceiling grid, hence the term “recessed.” Typical fixture sizes include 1×4 troffers, 2×2 troffers, and 2×4 troffers. This type of interior lighting is in a range of building types and workplace usage and is commonly used to provide illumination for commercial lighting, industrial lighting, retail lighting, warehouse lighting, and classroom lighting applications.

Below are a few image examples of troffer lighting applications. The below photos are by no means representative of all the types of 1×4 troffer, 2×2 troffer, and 2×4 troffer applications, they are just a quick visual sample.
