  Do you think we will ever change our power grid to have a higher frequency so that our bulbs don’t flicker when we record things?

    Good LED bulbs have a smoothing capacitor after the full bridge rectifier. This allows the LED to maintain most of its output during the low points in the cycle, resulting in minimal to no flicker when recording.

    Buffer the input in a battery then use dc out from the battery to power your lights, no flickering. No need to reconfigure the entire grid and every device on it for niche applications.

      Just rectify the AC, if the voltage isn’t too much.

      You don’t need a buffer unless the power fluctuates.

        Rectifying the AC, even with a full bridge rectifier, will still drop to zero every time the AC voltage crosses the zero line. So usually a capacitor is added to buffer this output. Its capacity depends on the size of the load.

    If lights are flickering when you record videos, you probably need to change the settings on your camera to match your country’s grid frequency. Almost every video recording device will have a 50/60Hz setting somewhere.

    How about banning flickering lamps? I’d ban screeching power adapters too.
