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. Human Centric Lighting sounds awesome, doesn’t it? Recently... Continue Reading →

Fine Homebuilding Kitchen

Imagine the future: light helps you keep your balance as you age, cuts down on point sources that cause glare, minimizes sleep disturbances, and helps you see what you are doing better than ever. Wouldn't it be nice?  Pushing these boundaries requires experiments like our recent lighting makeover at my parents' farmhouse in Illinois.  The... Continue Reading →

Red Light, Green Light

A few years ago I heard a simple phrase from a leading lighting researcher: "Light is a drug." Like most drugs, light causes chemical reactions in our brain and body.  Moods change, biorhythms change, migraines disappear. Wait, migraines? Dr. Mohab Ibrahim, director of the chronic pain clinic at a hospital in Tucson, Arizona, has an... Continue Reading →

Oops, I did it again.

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...

Rough. Drafts.

There is a lot to learn when it comes to lighting, and I love writing about it (you have probably figured that out already).  Sometimes, a picture (or a moving picture, in this case) may be worth the proverbial one thousand words.  And so we enter into video.  We have a rough draft- and it...

The Good Old Days of Light

I like to believe that I am a forward thinker and not a person who looks behind longingly at The Good Old Days. Most of the time. When it comes to architecture, I love where the world is headed.  We're seeing modern homes with large expanses of glass, schools with huge amounts of daylight, factories... Continue Reading →
