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

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
