A widespread DC socket standard for LEDs would go a long way towards this. The fitting could then do the AC to DC conversion separately and could house any controller, but the LEDs itself would be very simple.

  I’m too European to get that. Would you not like a DC light socket standard? It’s quite the waste to have AC to DC happen in every light bulb.

    Poe might be an option. It would also reduce the amount of crappy devices taking up WiFi bandwidth. It would be a pain to retro fit though.

      AFAIK lightning solutions using PoE already exist in commercial space. For general use, I'd assume that PoE hardware/software is a bit too expensive, but maybe we can have similarly priced bulbs/lightstrips than Philips Hue.

      Eh... not a great fit. POE++ Super Extra is 100W per port. Figure a dumb 75W-equivilent is like 10-14W. You get maybe 8 bulbs per run assuming everything is exactly as rated. But specifying doesn't work like that. You won't know if someone will plug in 24W bulbs. You need to plan sockets for the most someone could use. If you wanted DC retrofit, you would be better of doing it at the light switch and just using the same wiring and sockets.

    California government is large, and exceeds past the role of government in other states. They pushed for all new construction to require a GU24 bulb socket because it would "mean" high efficiency. It was a massive failure with practically the only market in the world for the GU24 connector in CA. Now, they rolled it back so you are still required to use high efficiency bulbs but the connector isn't important anymore. No concern that of all the GU24 fixtures that will need to be replaced and sent to landfill.

I had some "down lights" in an apartment I lived in in Australia that did this Annoyingly for a single (small) room it had *three* switches, each controlling two lights. The ones on either side of the room were perhaps 8 feet apart, with two more at the near end of the room (about another 4 feet from the first two) Replacing them with compatible smart bulbs of any kind due to them being DC proved surprisingly difficult in Australia. Though I suspect countries with larger markets would fare better

This is such a simple and obvious idea, I don't know why nobody does this. I guess they can't agree on a standard, but the first company to create this would probably also set the standard (and the second one would set it again).

  Power losses mainly. I did 24V wiring on campers and boats, and it's ridiculous how much copper you have to put in and then still have issues with the voltage drop. 110 or even better 220V AC is just so much better in that respect. If only people wouldn't call a diode bridge and a couple of capacitors a driver. Which is what you'll find in most of LED bulbs, and which is why they die so fast.
  - stavros 3y ago
    The adapter would still screw into the 220V bulb socket, but you could then just replace the LED part when it burns out, rather than having to throw out the voltage converter as well.
    - lstodd 3y ago
      Wouldn't it be better for the LEDs to not burn out in the first place? Because this was and is achievable.
      - stavros 3y ago
        That is an orthogonal concern, the two aren't really comparable. It would be good if the LEDs didn't burn out, and it would also be good if we didn't have to throw away both parts when one failed.
        lstodd 3y ago
        I can't agree with this. If we're redesigning the power supply it's actually much cheaper to make it not cause burnout on the LEDs than to make it replaceable.
