A client recently asked my opinion on power over ethernet (POE) and DC microgrids for their next building upgrade project. They received a hard sales pitch on POE lighting and controls and wanted some rational counterpoints. Here’s my two cents, after talking to a folks...
As trade tensions continue to escalate between the United States and China, the lighting industry can’t help but be impacted. Most of the big brand lighting manufacturers headquartered in the United States manufacture vast swaths of their lighting products offshore. So it’s no surprise the...
Many lighting retrofit designs fail to fully consider egress and emergency lighting systems. These systems are usually required by state code and often superseded by local code or the requirements of the local authority having jurisdiction. Failure to provide adequate egress and emergency lighting controls...
You can evaluate energy performance and target energy saving projects using graphics like in the case of one of our portfolio clients where we evaluated lighting control system performance looking at lighting power density (LPD) and energy use intensity (EUI). Data visualization is one of...
Averages hide things, blending together the highs and the lows arriving at something in the middle. But the end result is a product that doesn’t accurately reflect the diversity of the whole which can be a BIG problem when it comes to estimating savings for...

In a previous post, I wrote about smartphone apps and their inadequacy with respect to illuminance measurements (that is, their ability to measure footcandles or lux). That post took a deep dive into why smartphones are not up to snuff as a professional light meter....
I will not budge on two things. First, of Richard Kelly’s Three Components of Light, ‘play of brilliants’ is the best element of lighting design (who doesn’t love sparkle?). Second, smartphones are not light meters. Say it again with me. Smartphones are not light meters. Yes,...
Exterior lighting pushes back the darkness and can make the otherwise intimidating nighttime environment more welcoming and functional. But lighting can also impact our well-being. The extent of that impact is currently under debate between the American Medical Association (AMA) and Illuminating Engineering Society (IES)....
I recently held a session on Best Practices for Lighting Audits at PG&E’s Pacific Energy Center and someone asked me something which truly intrigued me about cheese (?!) and lighting. I love sharing my experiences in these classes and picking up tips and tricks from...
