The article offers some of the standard arguments I’ve read over the years about why we like incandescent lighting, its relationship to the spectrum of firelight, and how an office lit with 5,550 Kelvin fluorescents feels totally different than daylight at 5,550 Kelvin daylight. This is where the author and I agree, perhaps for different reasons. I personally despise fluorescent lighting, especially the… Read More »On The Love Of Incandescent

Some Thoughts On Color Mixing

Over the years, many different lighting companies have come up with many different ways to do color mixing of their lights, and today I’d like to pontificate about some of the different methods and their strengths and weaknesses, and how they fit into different areas of design. Flags: the mixing glass slides back and forth on tracks, moving into and out of the beam. The big strength of the flag system is the speed of the system, but what tends to happen is that as the flags ease into the beam, the gradations show up as visibly uneven coloration within the aerial beam. This isn’t always noticeable, especially during faster moves or on mixing cues where the flags move on… Read More »Some Thoughts On Color Mixing
