Visit CIRCADIAN Light at the Northeast Petrochemical Conference & Exhibition in Pittsburgh, PA. Booth #124, June 20-21, 2019.

Learn about the New API RP-755 Lighting Requirement, critically important for 24/7 industries.

Can your Work Environment Lighting meet the New API RP-755 Lighting Requirement?

  • Has More than 15% blue rich white light during the day to promote alertness.
  • Displays UL Verified Mark to indicate less than 2% blue at night to minimize circadian disruption.
  • Automatically cycle from blue rich in the day to blue depleted at night.
  • Maintains high quality white light over 24-hour cycles to keep areas well-lit.
  • Beware of faulty substitutes that just dim the lights --- Color-Tuning lights Don’t Qualify.


True & False CIRCADIAN LIGHTING: How To Protect Occupant Health & Productivity 

Many lighting products are incorrectly labelled "circadian." This is because the word “circadian” has recently entered into lighting industry vernacular often with limited understanding of its precise meaning. This can create confusion for architects, lighting designers and specifiers. 

So, what is circadian lighting? In 2018 the IES and RPI's National Science Foundation funded LESA center workshop report concluded that, “Merely adjusting CCT, light intensity, or even SPD with time of day does not qualify a lighting system as 'circadian.' CCT color tuning products …should not be labelled 'circadian' unless they have been demonstrated through properly designed clinical trials to be capable of optimizing the phase, amplitude and/or entrainment of the circadian system to promote human health and wellbeing.”

How to Create an Effective Fatigue Risk Management Program for your Emergency Service

Shiftworkers exhibit higher rates of certain health issues and are more than twice as likely to be absent from work than daytime only employees. Managing a shiftwork lifestyle can be challenging and lead to health issues as well as family and social stresses. CIRCADIAN will discuss the physiological stress of working 24/7 shifts and how that can affect the shiftworker and emergency service organizations. CIRCADIAN will provide a high-level overview of Fatigue Risk Management Systems (FRMS) techniques and tools which will improve conditions for round the clock service providers while maximizing their performance and work/life balance.
