Agreeing on the flicker. I don't think it's surprising that it's so common, though--undimmed lights are cheapest to power by not making proper DC out of the AC

Agreeing on the flicker. I don't think it's surprising that it's so common, though--undimmed lights are cheapest to power by not making proper DC out of the AC coming from the socket, and dimmed lights are cheapest to dim by slow PWM (pulsing ~100 times per second) without including inductors to flatten the pulses.
- was_a_dev 4y agoIs there a way to tell if an LED bulb doesn't flicker
- layer8 4y agoSlow-motion video recording.
- pflanze 4y agoIt's also easy to see when you move your hands quickly back and forth in front of a dark background with fingers spread apart, instead of the fingers being blurred you'll see their image repeated distinctly many times (like a fan).
- was_a_dev 4y agoTechnically yes, but unfortunately that means purchasing the bulb beforehand
- pflanze 4y agoI don't know of a way around that (short of maybe finding reviews).
