What is going on with ceiling fans

    It’s the same story for basically any part of a home. Faucets, furniture, tubs, windows, doors, floors, lamps, you name it.

    What a testament to the manufacturing advances that have made it profitable to cater to every possible taste, budget, and architectural layout. It’s incredible actually.

      I just wish there was some way to replace the LEDs on these things when they inevitably die. And, no matter what large number of years or decades are slathered on the box, inevitably at least one LED panel will blow out three to six months after purchase, nominally still in warranty but good luck getting any service under it, I'm sure. If there was, there could be a place for at least some of these in a house, but the amount of crap that you have no choice but to throw out as soon as the LEDs fry is insane.

      This is why my "fancy" lighting fixture is an old track (whose proprietary lights died a long time ago) wrapped with an extension cable with 5 standard sockets on it, and some standard light bulbs in it. We dress it up with ribbons and stuff for the seasons. It doesn't look as nice as any of the things in that article, not even the gaudy and tasteless ones, but when a bulb burn out, I put a new one in and get on with life, I don't throw out an entire fan and buy a new one.

      I'm old enough to remember when I was promised LEDs would last approximately forever without having to be replaced.

        Your local inspector may have opinions about this, but you can buy all the components of an excellent LED system from your favorite electronics distributor, e.g. DigiKey.

        Don’t waste your time or eyeballs with “driverless” devices. Get a chip-on-board LED, e.g. Bridgelux’s products, along with a matching driver (I like Luminus Devices’ small drivers - they have good startup and dimming behavior).

        Aside from usual electrical safety, anyone designing what is effectively a luminaire needs to make sure that the driver matches the LED and that the driver is compatible with the dimmer in use. Matching the LED means that the driver produces an amount of current that that LED’s datasheet data is acceptable and that produces the amount of light that is desired and dissipates an amount of heat that can be managed. And that the LED’s voltage drop at the design current is in range for the driver. These LEDs are constant current devices, so you’re thinking about current first and voltage second. Read the datasheets!

        Unfortunately many cheap luminaires are based on modules that are either driverless LEDs (which are terrible due to essentially unavoidable flicker and lack of regulation) or are line-voltage-supplied integrated devices. These are likely to be hard-to-find modules. There may not be room for a discrete driver and separate LED.
