Attachment J-1502000-07 Interior and Exterior Lighting Systems.xlsx

This is an asset inventory spreadsheet for interior and exterior lighting systems across multiple Naval Research Laboratory (NRL) facilities located in Washington, District of Columbia. The file documents comprehensive lighting infrastructure across 48 separate NRL buildings (NRL-1 through NRL-208), including detailed asset information organized by location, system classification, sub-system type, quantity, unit of measure, and installation date.

The lighting systems inventory encompasses five primary categories: branch wiring/electrical distribution, exit lighting, exterior lighting, interior lighting (fluorescent, incandescent, and LED variants), high-intensity lighting, and explosion-proof lighting. Asset quantities range from single units to over 1,200 fixtures per building, with installation dates spanning from 1956 to 2021. Interior lighting predominantly features fluorescent troffer fixtures (representing the majority of installed units across floors 1-4), supplemented by pendant-mounted, surface-mounted, recessed can, and pendent-mounted configurations. Exterior lighting systems include high-pressure sodium, metal halide, quartz, incandescent, low-pressure sodium, halogen, and LED wall pack fixtures at varying wattages (55W to 1500W). The inventory also identifies newer LED pendant and strip fixtures installed as recent as 2015-2017, indicating ongoing modernization efforts. Branch wiring assets are measured in square footage, with facility-wide distributions ranging from 65 SF to over 150,000 SF per building, reflecting the scale variation across NRL properties.
