    This isn’t what Christmas looks like. It’s what a vape shop looks like. Or, worse, a gaming PC.

    😆

    My only gripe with the LED ones is that they always seem to have a high-frequency flicker which gives me a headache. Other people have told me they don’t notice it, but I do. I wanted to replace the clear incandescent ones with LED but couldn’t deal with the flicker.

      But capacitors are so expensive, it’s like a whole 10¢ extra to filter it out so it doesn’t flicker!

      It is either a 30 or 60 Hz flicker, depending on how they built the electronics. It is 30 Hz if they did include an inverter and 60 Hz if they did.

      Without an inverter, it will be off for 50% of the time. With an inverter, it will always be on, but sometimes dim.

      With better electronics, it will be steady on, but that’s not common in christmas lights.

        Wouldn’t that be 60 Hz without a rectifier, and 120 Hz with one? If the voltage crosses zero twice per cycle, but goes negative only once.

        Not strictly always true, if the lights have any kind of dimming capability (like many of the ones with automated patterns) you’ll likely be dealing with PWM which means the time spent lit can vary significantly

      I have 1,000% light perception, I notice the flicker on almost every LED I’ve ever seen.
