Why should I trust you? Are you truly "experts"?

First, at Circadian Lighting Advisors, we are lighting people. From manufacturing, lighting design, energy savings management, rep agency consulting, controls commissioning, project management, and distribution and contracting, we know the lighting industry. Like almost everyone in this field, we can say that we were not intending to be in the lighting industry while we were in high school. We fell into lighting.


We always looked at lighting as an emerging technology that could do so much more... more than just illuminate a room. When the relationship between human circadian rhythms and indoor lighting became apparent, we jumped in to discover what the issues were.


Today, we're a group of experienced circadian lighting experts who developed the existing methods for:

  • Creating a circadian luminaire score methodology
  • Developing the online tools that enables lighting specifiers to search for luminaires
  • Creating a method for capturing thousands of measures in an indoor space and outputting a floor plan illustrating the circadian scores


After developing the tools to ensure that lighting projects could be designed and measured to ensure circadian effectiveness, we committed to educate the marketplace. Still, we heard that there was general confusion about what to listen to... what to focus on, and even how to increase the companies revenue in this climate where lighting is struggling to figure out how to gain market share.


Yes, we are experts.


In other words, we've got the market know-how to help companies from the lighting industry deliver circadian solutions that meet your customer's needs.


So you're in good hands.
