High Tech Lighting Benefits from High-LR Ceilings

High LR ceilings (ULTIMA, OPTIMA®, both LR 0.90) are engineered to reflect up to 90% of the light striking their surface.  The advantages, substantiated in research by the Weidt Group ("Performance Benefits of High-Reflectance Ceilings," 1996) are:   

  • Substantially brighter spaces - up to 25% more usable light (foot-candles)
  • Reduced energy costs and consumption - as much as 18%
  • Exceptionally balanced light diffusion - due to the consistent surface finish
  • Reduced Light Loss Factor (LLF) - because their soil-resistant surfaces remain highly reflectant
 
 Direct Lighting       Indirect Lighting

ARMSTRONG HIGH-LR CEILINGS:

  • Reduce indirect lighting costs as much as 18% 
  • Reduce glare and eyestrain

RENEWED ATTENTION

Growing awareness of new, energy-saving lighting often overlooks the integral role of the ceiling.  A high light reflectance ceiling - LR 0.83 or greater per ASTM E 1477-98 as referred to in ASTM E 1264-98 - makes these lighting systems, especially indirect lighting, more effective while further reducing energy costs and consumption.

  • Continually rising energy costs
  • Stringent new codes reducing energy budget limits
  • Heightened awareness of lighting's impact on worker comfort and workplace effectiveness

Armstrong ceilings with even higher light reflectance (LR 0.90) such as OPTIMA® Open Plan and ULTIMA provide:

  • Significant cost reductions - as much as 18%
  • Reduce occupant eyestrain - identified in a Harris Poll as the number one office health hazard
