STACK PACK delivers exceptional value with a jobsite-ready design and unmatched versatility—featuring fully switchable lumen output (30L/40L/50L) and color temperature (3500K/4000K/5000K). But its true advantage is in how it ships: four 2x2 fixtures in a single box, drastically reducing packaging, waste, and handling. STACK Pack requires minor toolless assembly prior to installation. Simply insert the connector on the driver to the connector on the housing, and then slide in place. The STACK PACK lens installs easily into the center channel. Drywall grid adapters are sold separately. STACK PACK is the perfect choice for schools, commercial office spaces and many more applications.
