What is going on with ceiling fans

    My wife and I were out recently looking at ceiling fans to replace the one in our dining room, which has committed no crimes, other than having the appearance of being very much from the 1980s.

    I was taken aback by how few of the fans had replaceable lightbulbs! In the entire store there were maybe three or four options with a replaceable bulb!

    Call me crazy, but a nonreplaceable LED is a complete dealbreaker. I go through so many LED bulbs! I don't know if my electricity is like particularly bad or if that's just normal? The first LED bulb I ever bought (Shout out EarthLED) in 2008 for like $30 is still going strong, but every bulb I buy these days lasts like two years tops.

    Anyway, we did not buy a fan.

      My pet peeve is remote controlled fans. I want a physical cord or switch. The remotes are so flaky and annoying.

        DC fans are infinitely superior to AC fans (noise, torque, longevity, etc.), which is unfortunately why this became a thing.

        There's no clean mechanism to control a fan's speed in-band on a normal AC wall switch.

          There absolutely is. If you have a fan with a light controlled by separate wall switches, you have two hots running to the fixture. Take one, and leave it unswitched always on to the fixture, and use the second switch (or fan controller) and use it as an input to the controller on the fan. Done.

          Unfortunately, I haven't seen this implemented anywhere.

          This message brought to you by the hours I've spent annoyed by exactly this misfeature in our new bedroom fan. Fanimation does sell a wall mounted remote that can be wired inline with a switch, so at least there's a single point for master power and a remote you can't lose. Unfortunately, there's a noticeable delay between flipping the switch and the light turning on.

            This is common, but it's also not uncommon for only one circuit to be wired. The "clean" qualifier is because even if you have that line, you don't have a common DC ground.

            Many Z-wave switches use the three-way traveler line for out-of-band signaling (instead of a traditional three-way switch arrangement.) (Homeseer, Inovelli, etc.) This line will communicate dimming, double taps, etc.
