    9:30 I'd be shocked if that resistor had managed to fail without looking the part, but I suppose it could have cracked internally. One thing I have seen while doing repairs, is some types of solder joints are seemingly completely impervious to multimeter leads. I don't know if it's a specific type of solder that forms a strong oxide layer, or what, but I've legitimately had to add solder just for probing. Sometimes putting the leads on top of the component works instead. P.S. I'd probably suspect a bad electrolytic capacitor. There wasn't any smoothing present on the rectified voltage.

    I have one, and I actually kind of like it. My dad and grandpa both got one for Christmas one year, and after my grandpa passed I got some of his tools, including this one. And I do occasionally find uses for it. The one complaint I do have is the size, it's got a much larger profile than the meat powered adjustable open end wrench, so it doesn't really fit in tight spaces as easily.

    My early led bulbs used to last about 6 months or so. About 5 years ago I installed solar and an inverter, and since then I have led bulbs that have lasted from then and still going. (One or two have failed, but none that I have replaced since switching to the inverter). I compared the waveforms from the mains and the inverter, the inverter is significantly better but also doesn't have the pulses, spikes and surges which I see on occasion on the mains. I'm guessing that is significant. Anecdotally, if my sound system is on the inverter (which it usually is) it sounds great. On odd occasions under heavy cloud or rain I am forced to switch on the mains to compensate, and then the inverter routes the mains through and the house is on mains. My sound system doesn't sound as good, and I have an audible hum on the speakers.

    I noticed LEDs get dimmer over time too. I replaced a bulb in a ceiling light with an identical bulb, bought at the same time but never used, and I nearly blew my eyes out. So after 1-2 years, they lose a good % of lumens too

    the led light cirquits at college where much worse than the one in that chinese one. as they had no stabilisation or such. but might be some parts are designed to fail faster, like pushing components to their absolute limits intentionally while it would cost 1 cent more to make them much more capable. bad solder joints also are such a example, as these days many things are designed with the intend to fail rapidly. surface mount parts get loose solder joints much more easily than through hole, to fix that they normally are pretty flat and with a wide area, so all those companies surface mount soldering through hole components that is a easy recipe for failure. on some expensive brand or designer lightbulbs they even add special parts which essentially act like a timer to make the lightbulb die after a certain amount of time, or they intentionally overdrive the leds or add special materials which slightly change colour to make their colour change over time so that when one light is replaced all have to be replaced, as in most modern companies and such they don't like different coloured leds(I guess companies are led racist, has to always be in led psychopath mode. also you mentioned 5000k being psychopath, but here in netherlands many busineses want even higher k numbers for their buildings and rooms. next to that somehow all companies want such insane intensity from leds that your eyes almost fry themselves when entering such a building.

    You know it’s possible to build an LED bulb that runs the LEDs directly off line current, right? I built one that’s nothing but LEDs and wire. It runs on 120V AC and sits inside an A19 enclosure. It’s been running continuously for over ten years.
