BS* + Beer Show

*BS = Building Science When Green Building Advisor and Fine Homebuilding friends asked me to join an episode of the BS* + beer show, I was honored and a little scared. Why? Because builders and lighting designers do not always get along. In retrospect, I need not have feared. BS* + Beer is a weekly... Continue Reading →

Seven Saintly Solutions

Seven Saintly Solutions, Presented by David Warfel from DMF Lighting on Vimeo. One of the perks of starting your own company is that you get to pick your job title. At some point I decided that "Chief Evangelist of Light" (CEL) would be my own. Evangelist is a term that can have positive and negative... Continue Reading →

Human Centric Lighting…or Profit Centric Lighting?

Human Centric Lighting (HCL) is a nebulous term quickly replacing Circadian Lighting as the go-to language for describing lighting strategies intended to improve our lives. The more expansive idea behind HCL is that it includes circadian rhythm science but also accounts for moment-to-moment human wellness, comfort, and needs.

Dr. Mohab Ibrahim, director of the chronic pain clinic at a hospital in Tucson, Arizona, has an... Continue Reading →

One of those rules is to never mix warm white bulbs (yellowish) with cool white bulbs (bluish).  I learned this rule back in the fluorescent day by looking at ceilings where some bulbs were pink and some were blue and the end result is that the...

Lighting isn’t brain surgery…?

I frequently hear myself saying that lighting is not brain surgery, that getting it right just requires the attention of a dedicated experienced professional. I might be wrong. (Not literally.  I could never do brain surgery because I would pass out as soon as the knife dug in.  I'm getting faint just thinking about it.... Continue Reading →

Change is the Only Constant

I am as guilty as the next lighting designer.  See my design above for proof. Once upon a time, light indoors depended on light through windows or flames from candles, lamps and fires.  The windows were automatically scheduled to turn on slowly in the morning and turn off slowly in the evening.  They changed intensity...
