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...

Finding the perfect downlight feels as easy as finding the end of the rainbow. History and literature are full of great tales of adventurers seeking the unattainable. There is the quest for the Holy Grail (“We’ve already got one.”), the search for the fountain of life (find it or die trying), and the hunt for... Continue Reading →
“Using CCT as a proxy for the biological potency of light cannot be justified.” -Esposito, T., Houser, K. Click HERE for full article. A few weeks ago I revisited the promise that light can help us feel better and drew parallels between taste and sight. Food, when prepared creatively, can deliver momentary pleasure on our tastebuds but it takes... Continue Reading →
This post is a continuation of my Don't/Do This: Primary Bedroom exploration. My Don't/Do This series are a lot of fun to sketch and imagine. Too much fun, perhaps, as the post on primary bedrooms has now ballooned into three. Without much forethought, I find myself creating an increasingly comprehensive series aimed at comparing and...

An unpredicted grand finale to my 1THING posts takes me to the darkest places of our homes. It is early December as I sit down to write the last 1THING: New Build post of the year. Like my own life, I started with a plan and a clear vision for where I was headed with... Continue Reading →
I am working on a article extolling the virtues of low voltage power distribution and I find myself wondering, as Mike Teolis from Colorbeam said, "can anyone give me a valid reason why we need 120 volt infrastructure for a 14 watt LED putting out 1000 lumens?" I love to geek out on lighting technology... Continue Reading →
A year ago, when I was planning my 2022 blog writing, I imagined a series on gear where I could talk shop about different fixtures and technologies. I saw myself geeking out on light bulbs, recessed adjustable downlights, tape light, step lights, and any other piece of equipment we use in our work every day.... Continue Reading →
With just two months left in my 2022 blogging plan, I'm already growing nostalgic about my 1THING posts. The artificial constraints of narrowing all lighting down to just a single solution for new builds or plug-in retrofits for a handful of common spaces gave me focus and structure for the year, and the sketching exercises...

A few years ago I spent a rather silly amount of time buying and testing light bulbs from local retailers in the hopes of finding something I liked. I failed. I tried again in 2020 and found a few I liked and our team built a buying guide around them. Now that buying guide is... Continue Reading →
A few weeks ago I had fun detailing what happens in children's bedrooms and why typical lighting falls short of serving human needs. This week I take another crack at the kids' rooms, this time for my 1THING: Plug In solutions series. Honestly, it is a little tougher to light a child's bedroom with plug... Continue Reading →
