    It always amazes me to read that people like their LEDs.

    We've tried a dozen or more different LED bulbs from various sources, and without exception, no matter what the purported color temperature, CRI, lumens, wattages, etc.,  they have all SUCKED, not to put too fine point on it. (Too dim, overall color too weird -even with the 2700K bulbs, poor color differentiation, too focused, too harsh, and several even made a constant hum.)

    What ones we haven't been able to return have been relegated to outbuildings where they are rarely tuned on, so they will no doubt last for centuries. (Unless the extremely cold winter temps get 'em first, which was the fate of the CFLS we tried and rejected.)

    I'm still hopeful, but not seeing anything I can live with, notwithstanding the undoubted energy savings.

    I prefer incandescent light (and full-spectrum incandescent at that), and since I heat my very old northern NY house with wood (which we harvest from our woodlot) and generate power from our solar panels, I don't feel too much guilt.  And anyway since we don't heat the second floor, at all, the  warmth from our desk and bedside lamps is a feature, not a bug.

    We only have table and wall lamps, no hardwired fixtures anywhere in the house so maybe that's part of the problem. Maybe there are better bulbs suitable for cans and such.  But so far, we've had no luck.

    I wonder if the acceptability of the light generated by LEDs varies by region since the ambient light quality differs so strongly from one area of the country to another. I also wonder if routine, daily, exposure to fluorescent lighting in workplaces changes people's internal sense of what good light "feels like".

      I think your last sentence is right on point.  Tiffany lamps transformed the harsh light from an incandescent bulb into a rainbow of beautiful light.  So what happened?  They were relegated to the attic, while people sought out lighting that was little different from a bare bulb.  Then we got bare bulbs, then bare halogens.  From floodlights to "needle" lights, we are assaulted by painful lighting.  And most people like it.

      I definitely agree with your note about heat being "a feature, not a bug", but that only applies for a few months of the year here in Florida.
