--- Quote from: coppice on April 03, 2023, 09:33:13 pm ---For decades the best colour rendition available in a light for artists was a rather inefficient fluorescent tube called "graphic". It used different glass to get a the intensity of those 2 main mercury lines down, and a phosphor mix chosen for accuracy over efficiency. They were generally driven from an electronic ballast, to eliminate flicker. --- End quote --- There were many, and the standard for color-accurate graphic design is the so-called D50 light. (Daylight, 5000K.) I haven’t been involved in the graphic arts for a long time, but I assume these will eventually be implemented with LEDs, if they haven’t been already. The fluorescent tubes are still available though. |

This thread is reminiscent of the vacuum tube vs solid-state argument, but now it's about light instead of sound. ::) |

I would have thought that, with your weather switching to shit, increasing wildfires etc, you would want the whole world to have an environmentalist policy! |

I just despair at the mass stupidity and hysteria over everything. We live on a dynamic planet, things change, we are in a small snapshot of it's history and our mere existence and evolution is a statistical fluke, let's not push our luck. |
