Feeling a bit groggy as you start your workday today? Hundreds of millions of Americans will be a bit less productive this morning, require a bit more coffee, and be a little more grumpy than usual. Just like we were last year at this time, and likely will be again next year unless we change... Continue Reading →
It is time to retire your light switches and dimmers…if you want to get the full benefits of good light back into your life. Get them back? Yes, you and I lost out on natural light’s benefits when our ancestors decided houses were better than tents and offices were better than fields. They moved indoors,... Continue Reading →
A few weeks ago I got to geek out a bit with some lighting colleagues during dinner, a rare treat for someone who works mostly remotely. My Zoom conversations are almost always task-oriented, designed to accomplish something and then move on to the next one, and that makes unscripted, unmeasured, non-billable communication somewhat unusual- and...

Over the last decade or so, our family has taken a number of camping trips to some of the darkest places in the United States. What was the first lesson we taught our children about nighttime in the campground? Never shine your flashlight in someone else’s face. What is the first thing that greets our... Continue Reading →
I am continually amazed at the lack of color in our lighting, at home and at work. We wear colored clothing, drive colored cars, paint our homes and cabinets in color, and hang colored photos and art on our walls. We choose colored carpets and colored ceramic tile, we buy colored backpacks and purses, some... Continue Reading →
Ouch. This post, more than others, paints me as a rather entitled and spoiled person. I'll work on that, but for now let's just assume the best- that the lessons I learned can help others live better lives. That is what lighting design - and this blog - is all about. A few years ago... Continue Reading →
After more than twenty years in the lighting profession it is tempting to think I know it all. The truth, of course, is that I possess but a tiny fraction of the collected knowledge of light- and our body of understanding is growing much faster than I can learn. Let me give you an example....
