A few years ago I wrote a pulp piece for Houzz.com on how to choose the "right" color temperature of light. At the time there were just a few choices homeowners faced with lighting: choose 2700°K warm white, 3000°K not-quite-as-warm light, or perhaps 3500°K "neutral" white or 4000°K cool light.

This post is the third in my 1THING: New Builds series designed to boil better lighting down to the bare essentials. And I promise I'll get to the subject - living rooms - in just a moment. But first, I owe you an apology. One of the benefits of blogging - at least the way... Continue Reading →

Would you be concerned if you had to eat McDonald's hamburgers for breakfast, lunch, and dinner for the rest of your life? Did you know you are probably doing the equivalent with your light? Without food, we die. We need food, regularly and sufficiently, to survive. Many of us now have the privilege of moving... Continue Reading →
I was recently asked to define the catchy term Human Centric Lighting, or HCL. We love lighting acronyms in the lighting world, so I came up with a few more than my previous post on this subject. Consider yourself warned. At its most essential, Human Centric Lighting is an attempt to undo our mistakes of... Continue Reading →
https://youtu.be/XkyjKxRkKZM What do Royal Caribbean cruise ships, Apollo mission control, and lighting designers have in common? The convergence happened before the pandemic, but it wasn't until recently that I found out a promotional video had been made and posted on Youtube. It can be hard to see the results of our work, as so much... Continue Reading →
https://videopress.com/v/67XaWGxf?preloadContent=metadata If you are one of my faithful readers that was sad in 2020 because I wrote only half my normal quantity of posts, I owe you an apology and an explanation. Of course, 2020 is a year that will go down in history as the year of "no apology needed." I'm sorry I didn't... Continue Reading →
