LED luminaire fits into restricted plenum spaces

The LED zero plenum troffer (LZPT) is a high performance luminaire for restricted plenum spaces. It targets the education, healthcare, retail and commercial industries that have restricted plenum spaces but still require a certain distribution of light.

The telescoping housing requires only three inches above the ceiling at one end of the fixture. Once installed, a housing height of 1.5-in. keeps the fixture from intruding into the useable plenum. The troffer provides 60,000 hour LEDs at L80, offers four LED color choices. It also offers lumen packages ranging from 1,900 to 9,100 nominal lumens, features color consistency to a 3-step MacAdam ellipse and 82 CRI, and provides a five-year warranty.
