God, LEDs must be the worst scam foisted upon us by governments. Flicker, lies about the lifespan, and now you say I must replace the entire lamp when it fails

God, LEDs must be the worst scam foisted upon us by governments. Flicker, lies about the lifespan, and now you say I must replace the entire lamp when it fails rather than just the bulb.

I don't think there's any malice. They're far superior when it comes to energy consumption. And they generally work well. They're just part of a general trend that it's hard to find high-quality products anymore. Unless you have industry expertise, it's extremely hard to determine which appliances are usable. Traditional DYI stores sometimes provide that expertise, buying online it's nearly impossible to search for quality.

  It is malice. The government wants you to consoom while simultaneously lowering your quality of life. "Traditional [DIY] stores" are something else the govt is desperate to get rid of.

> LEDs[' dark sides] ...Interference with medical equipment (this lab I knew found out that their EEG malfunctioned when the new lamps were on...)

  Poorly built drivers, yet again - no EMI suppression. Virtually any switch mode power supply that has no suppression would have done that. The LED driver in virtually all cases is some SMPS.

    I know one of the tricks to detect flickering: look at the emitter through a camera, e.g. that of a phone. How would you instead check EMI - in general? (I am not a specialist in this area.)

      >I know one of the tricks to detect flickering: look at the emitter through a camera, e.g. that of a phone. This would be a really poor driver, effectively using the AC freq. and shutting off w/ each cycle/zero cross. Unfortunately, many are exactly like that. However - some cameras do have compensation for exactly this issue, and they may hide it. >How would you instead check EMI - in general? (I am not a specialist in this area.) Use an AM radio. (That would depend on the frequency and what not, but AM radios are a pretty neat trick to check)

        "Take an electronics testing lab with you next time you go shopping to be sure you're not getting some cheap crap" I miss the days of a restive wire shoved into the AC circuit.

LEDs are great when done well, corporations produce flimsy garbage. As if they have some interest in things breaking apart so you have to buy new ones.
