Zero Plenum™ Troffer High Efficiency Luminaire
A truly innovative luminaire, the ZPT™ fixture provides full distribution light with an aesthetic flair. The ideal solution for offices, schools, healthcare facilities and retail, ZPT™ luminaire offers several different looks to suit every taste. The shallow profile and patent-pending telescoping housing simplifies installation — even in the most restricted spaces.
ZPT is a high performance T5 luminaire that provides significant energy savings. Where a standard-lamp parabolic or lensed fixture uses 85W, ZPT™ fixture uses two standard T5 lamps, reducing the power consumption to 64W. This reduction can be even more dramatic using the optional 60W .95 BF ballast or one of Columbia’s dimming options.
