As Lighting Designers we cannot escape looking at lighting everywhere. Instinctively we look at the ceilings and critique lighting in any place we go to (just ask my wife). We also appreciate when lighting is done well, and welcome thoughtful lighting design as it raises the bar for all of us.
The same applies to products. While in a train in Tokyo recently (JR Yamanote Line in case you are familiar with Tokyo and are interested)—I came across an ad panel for a consumer grade color temperature changing LED surface mounted fixture.
