@Gargron @jk The LEDs themselves work on something like 12v or 24v DC, and here in the USA the supply voltage is (supposed to be) 120v AC, so every bulb needs a bridge rectifier and a voltage regulator and etc etc, all of which is less reliable than the LEDs. Especially when they've all gotta be stuffed into a tiny space to fit into a lightbulb. It really should just be a DC supply for each room or maybe each floor of the house, but we're not there yet.
