I dunno. I just bought the Sylvannia led traditional white lights. Flicker free. Finally.

That's what's so stupid about the whole problem - the solution is known and easy but it costs a tiny bit more to make so lots of manufacturers don't do it. It just needs to run off DC instead of AC. Simple.

I wonder if you could use four of the LEDs themselves to form a full bridge rectifier?

Electroboom needs a lemmy

Did you read "full bridge rectifier" in his voice, too?

[–] captain_aggravated@sh.itjust.works 2 points 2 days ago

I typed it in his voice.

Of course!

Would still need a capacitor or something or it would flicker at 120Hz (in the US) but that's not much more cost I would hope.

Also those 4 would flicker more than the rest of the string.

I just looked it up and I'm fairly certain it wouldn't work. Every time the output waveform gets too low then the led would turn off, which is what creates the flicker. An led needs a constant current to stay on constantly.
