The LZPT is an LED version of the Zero Plenum Troffer (ZPT) that is designed for restricted plenum spaces without impacting the required distribution of light. For installation, the patented telescoping housing requires only 3 in. 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 LZPT features an efficacy of 119 lumens/Watt, superior color consistency to a three-step MacAdam ellipse, and 82 CRI. The soft, uniform light distribution provides superior vertical illumination free from harsh contrast.
