The GeoPak Series consists of three compact Geometric wall-pack shapes in four popular finishes. The GeoPak can be applied as a Path of Egress fixture over the door alone, or as part of the total wall-pack building solution when coupled with the matching AC-only models. The Normally On/Emergency version has Spectron self-test/self-diagnostics and uses a long-life Lithium Iron Phosphate battery. There is also a heater option for colder climates. The GeoPak offers superior forward throw and side-to-side emergency coverage and over 3000 lumens in AC mode.
