    Me plugging my monitor into my mobo instead of my graphics card for three years. I thought I had just gotten reeeeally unlucky in the silicon lottery.

      Last time I did that I just didn’t get any output to the monitor, isn’t that how it’s supposed to work?

        Massively depends on the system.

        if you get a F series CPU with no igpu then you will likely get no output.

        one time i was testing something with the monitor in the motherboard, which worked fine, and then i put the gpu in the motherboard but forgot to plug the monitor in the gpu, and it showed a black screen.

        there might be systems where you can plug both a gpu and the igpu into the monitor and it’ll use one for most things and the other for games and stuff (i dont remember what that is called), but i have only ever seen that in laptops so idk

        It still wouldn’t be dim, it would either work or not. If it’s dim, it’s either a bad bulb or a setting on the light housing causing less voltage (I think?) to make it to the bulb.

          Aren’t you just describing dimmers, the topic of the post?

            Exactly!

            I’m saying the likelihood of the socket/housing causing a dim light is vanishingly small, so OP should have caught this 6 years ago if they had even a passing understanding of how lights work.

            My immediate asumption without looking it up was either it’s not getting the right voltage or enough amperage since electricity is generally passed through to lights, so it would either work or not. So, either the bulb is bad (old lights get dim) or there’s a setting somewhere on the fan or switch messing with the voltage or current. My first guess is the bulb, and if two fail, I’d check the fan.

            After a quick search, apparently dimmers are fancier than that, and they actually modify the signal instead of adjusting voltage or amperage. But my initial intuition wasn’t far off. The power is indeed on or off, and something else was interfering (the dimmer). If the fan didn’t have the capability to adjust brightness, there would be no reason to interfere with the signal.

            Simple logical deduction based on a passing understanding of electricity and lights would’ve led to the problem.

              it’s less that dimmers are fancier than you thought and more like adjusting voltage or amperage without ridiculous losses is hard and or significantly more expensive than you thought.

                Dimmers are incredibly simple with just triac and a variable resistor. However LEDs and CFLs do not work well with triac dimmers since they normally are expecting full voltage. Thats why you need “dimmable bulbs” becsuse they have circuitry to account for different voltages.

                Makes sense.

                My point is that a little bit of deduction should lead someone to the conclusion that the dim light was an intentional feature going “wrong” or a bad bulb.

              The integrated circuits in a lot of lighting fixtures (and you know OP’s light is run by integrated circuit because it can be controlled by remote) are basically a black box of complexity where things can go wrong in a non-intuitive way. Some kind of failure to deliver sufficient power to a particular bulb or LED or other element isn’t necessarily an indication of anything in particular.

                I doubt they’re all that complex. It’s probably something like a relay for the light, plus an analogue chip to control the dimming, which is likely completely separate from the digital logic (remote, motor control, etc).

                I wouldn’t expect OP to know anything about circuits though, but I do expect the bare minimum educated guess that a dim light isn’t likely a bad fan and is either a bad bulb or a setting somewhere, because a light going dim because on an electrical problem is incredibly unlikely.

      Depends on the CFL. I had to replace one in a fixture in my new house a few months after I bought it, and it was some goofy round one with a rectangular attachment point and some clips. Thankfully it was pretty easy to replace and was easily gettable from Dom Depot, but I was definitely surprised by the socket when I went to replace it.

        That sounds like one of those fixtures where the ballast is in the fixture and the bulb is just a bulb, similar to a regular fluorescent light fixture. As opposed to the screw-in CFLs that most people are familiar with where the bulb also contains the ballast.

        Those are kind of unusual in homes - I’ve mostly seen them in commercial applications like hotels and stuff like that.

      Worst case scenario just replace the light kit and check your wiring but yeah obviously that wasn’t OP’s issue

      Of course doing that with the fan still together/hanging is much more of a pain than just getting a new one, usually, especially if the fan is old. Most other electricians I know don’t bother doing ceiling fan repairs, they’ll swap em but any more than that’s not worth their time. I’ll do whatever but I’ll be up front about it.

      Especially since you’re usually doing it for retired folks who can only afford so much…

    Once you get used to proper bias lighting, suddenly overhead lamps become insufferable. I don’t know how people do it.

        Lights that you place behind things, like your bookshelf, TV/monitor, bedframe, etc. It’s so much more cozy and inviting compared to direct lighting. Like the other person said, a simple cheap lamp works wonders.

    Pro tip: Modern American fans are required to have a voltage limiter chip to dial down the lights. They fail. Lots. If your fan lights don’t work, buzz, hum, whatever, take it down and cut the little fucker out, wire back together with wire nuts.

    I’ve replaced two crappy fans with really nice units I found in the trash. 100 how-to’s on YT.

    Human Moment™. One of my former professors in Uni, the one I respected the most because she was one of the wisest and most perceptive people I’d met at that point, confided in us that it took her however many years since their introduction to realise that the small light on some wall-mounted light switches was meant as a guidance light if it’s pitch black.
