Notes on energy and performance table assumptions
1. Actual system values will vary based on the specific lamp, ballast, and fixtures.
2. Values shown for lamp/ballast systems are for general quick reference purposes only.
3. EFC system noted at 100% efficiency due to absolute test results versus the combination of lamp lumens and fixture efficiency.
4. Many variables can affect system output including operating environments and specific lamp/ballast performance characteristics.
5. Performance table compares the end of life lumen levels for existing systems to be replaced by brand new EFC system at 100% lumen maintenance.
6. Consult specific lamp ballast manufacturer catalogs for actual lumens, wattage, ballast factors, rated life and lumen maintenance for your system.6. Consult specific lamp ballast manufacturer catalogs for actual lumens, wattage, ballast factors, rated life and lumen maintenance for your system.
Notes on sample photometric layout
1. Refer to your AHJ to determine the minimum lighting requirements for your project area.
2. Temperature, obstructions, and other operational parameters are not considered in this layout.
3. Specific photometric reports should be generated for your project in order to ensure minimum required light levels.
4. Fixtures are mounted at 25’ high with 30’ spacing. 2 wall reflectance and .01 Ground reflectance used in calculations.
5. Sample photometric is to be used as a general reference and is not a replacement for a calculation based on your specific project needs.
