Multiple Fixtures 4' Distance From Wall
Notes:
• Illuminance values for multiple fixtures are based upon the center two units of a four
unit array. Footcandle values are centerline of fixtures and centered between fixtures.
1 footcandle = 10.76 lux. 1 foot(') = 304.8mm.
• Illuminance values are cosine corrected initial values with no contribution from inter
reflections from other room surfaces. Total illumination may increase from
contributions from other surfaces.
• Changing fixture spacing will affect illuminance level.
