PRODUCT INFORMATION PSG11 682 GENERAL INFORMATION Performance Data www.lithonia.com As Lithonia Lighting continues to improve the performance of its emergency lighting products, we also continue to improve the manner in which we communicate our products performance. Instead of relying on lamp iso-footcandle diagrams to compare one source to the next, we now perform point-by-point illuminance calculations to more accurately depict how our products will perform in real commercial or industrial applications. Point-by-point calculations depict illuminance coverage of an individual unit and/or multiple units in a space. Graphical representation of point- by-point for both a 3 and 6 path of egress are highlighted throughout the next few pages. In the graphical representation, the rectangle depicts the area where an average of one footcandle (FC) is maintained. The surrounding curve represents the minimum 0.1 FC isocontour along the floor. The coverage of an individual unit, as well as the maximum spacing that can be achieved with multiple units is depicted in feet. The footnotes detail all the relevant information necessary to replicate each layout using your own lighting analysis software and IESNA format photometrics.

Example of single ELM2 unit il- luminating a 6 path of egress. Quantum ELM2 MR24 Lamp Head ELM2 Peformance Advantage - Single-Unit Coverage 1 average illuminance of 1.0 FC over a distance of 24 on a 3 path of egress and 18 on a 6 path of egress. ELM2 Peformance Advantage - Multiple-Unit Coverage 1 center-to-center spacing on a 3 path of egress and 20 center-to- center spacing on a 6 path of egress. Example of multiple ELM2 units in a row illuminat- ing a 3 path of egress. QUANTUM Spacing Guidelines Notes 1 Meets Life Safety Code standard minimum illuminance of 0.1 FC and average illuminance of 1.0 FC. Assumes open space with no obstructions, mounting height: 7.5, ceiling height: 9, and reflectances: 80/50/20. Analysis based on independently tested photometrics. 2 Meets Life Safety Code standard minimum illuminance of 0.1 FC and average illuminance of 1.0 FC. Assumes open space with no obstructions, 3-foot-wide path of egress, and reflectances of 80/50/20. Quantum ELMLT Lamp Head ELMLT - Single - Multiple-Unit Coverage 56 ft. center-to-center spacing on a 6 ft. path of egress. 58 ft. center-to-center spacing on a 6 ft. path of egress. Quantum ELM2 LED Lamp Head ELM2 LED - Single-Unit Coverage illuminance of 1.0 FC over a distance of 24 on a 3 path of egress and 18 on a 6 path of egress.
