About this file
This document contains a photometric analysis and luminaire schedule for an interior LED lighting design project at an FBI facility. The analysis models lighting levels in seven rooms using Lithonia Lighting 2BLT2 20L SDSM LP835 16.06W LED downlights. It provides average, maximum and minimum footcandle readings at workplane height in each room and calculates illumination uniformity ratios. The luminaire schedule specifies 83 of the 2BLT2 16.06W LED downlights.
The related federal contract opportunity is solicitation number 15F06723Q0000316 for C3 Interior LED Lighting from the Department of Justice Federal Bureau of Investigation Headquarters Division. The solicitation seeks offers for an interior LED lighting design and installation project at an FBI facility.

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 80 / 50 / 20
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
6. Design is preliminary and should be reviewed by a Licenced Professional
