  > You have a decent analysis of the emitted frequencies here: That still shows something approaching a black body radiatior. The difference is just the planckian locus. In other words it does emit a full spectrum, just with a power distribution that mimics sunset light and not midday sunlight.

  "Incandescent light bulbs are nowhere near full spectrum." If you're considering microwave, radio, X-ray, and UV-C as part of full spectrum, sure. Otherwise, incandescents emit across the entire visible spectrum as a result of being a blackbody radiator. I'm even working with Scripps Institution of Oceanography on an experiment regarding exactly this right now.

  I assumed that full was always a relative term. You surely don't want devices that emit on the whole EM spectrum.

  I remember the transition, and “A/B testing” different rooms in my parents house as our last incandescents died, quite vividly. It was awful. It still is, but people no longer have good quality light for comparison.

    And you no longer have a room lit with incandescent to compare with the current, much improved offerings :)
