About this file
This photometric analysis report provides lighting calculations for two mechanical rooms in an FBI building. It details the existing and proposed lighting layouts and fixtures for Room 1 and Room 2, including luminaire schedules, light level measurements at workplane and ceiling heights, and calculation summaries. For Room 1, the report models replacing the existing fixtures with seven Lithonia ZL1D 5000K LED downlights outputting 5457 lumens each. For Room 2, it analyzes installing 20.8 footcandles of average illumination at the workplane using an unspecified number and type of new fixtures. The related federal contract opportunity is a solicitation from the Department of Justice FBI Headquarters Division for interior LED lighting under number 15F06723Q0000316.

NOTES:
1. All light levels are at workplane as indicated
2. Lumen output is based on anticipated lumen output at 1/2 the life of the LEDs
3. Light levels are calculated based reflectance values of 40 / 30 / 10
4. All lumen output is based on IES mandated of 25C, unless otherwise noted
5. Results are based on information provided to L& M. Changes to location, fixture, wattage will affect final results
