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 →
One of the unexpected joys of my 1THING: Plug In series is the discovery of new ideas and techniques that I can instantly apply to my own home- and the affirmation that some of the solutions that have evolved naturally over time in my home make some sense after all. This post has both. In... Continue Reading →
Recently I had the joy of virtually visiting a university classroom to talk about lighting with students. Since I can talk about lighting for hours and hours and hours, I usually ask the professor if there is a particular aspect of lighting they would like me to cover. One of my lectures this fall was...

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...

In the October issue of Designing Lighting, I appeal to the lighting industry to redesign the downlight. There are some amazing downlights made - and none of them are compatible with any other. We - the industry - are creating a potential mess for our consumers down the road, and this is especially true in... Continue Reading →
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 →
Today is a notable day in my own fictitious universe, for I am awarding myself the fake Nobel Prize for Illumination Yakking. I toot my own proverbial horn because of my "discovery" of another "disease" rampant in residential lighting and - quite by accident - the theorizing of an ancillary condition. Yes, once again I...

Budget conversations are my least favorite part of the lighting design process, though I have learned to dive right in rather than soft-pedal the costs and cause everyone bigger headaches down the road. The simple (unfortunate) truth is that really good lighting cannot be delivered for the same price as really bad lighting. Complicating the... Continue Reading →
I once read that the easiest ways to increase the sale price of your home were to paint the front door for a good first impression and add a deck to the back yard. I suppose adding a deck makes the back yard more enticing, perhaps even subconsciously saying to the buyer "purchase this home... Continue Reading →
