About this file

This file appears to be an electrical lighting calculation and layout drawing for Room 2D-117 (Special Procedure Room) at the VA Seattle facility. The drawing shows illuminance calculations and luminaire placement, featuring two types of lighting fixtures: MRI-22ATR-60-L840-OPL (24 units at 94.8W each) and MRI-R6DNLT_RPS-40-18-C (15 units at 29.8W each). The workplane illuminance calculations show an average of 210.64 footcandles, with maximum and minimum values of 301.0 and 97.0 footcandles respectively, achieving an average/minimum ratio of 2.17 and maximum/minimum ratio of 3.10. The floor plan portion shows the layout of these fixtures in a medical procedure room with adjacent control, equipment, and corridor spaces.
