alt Hacker NewsHow about Phillips flicker-free "warm glow" bulbs? I honestly have a hard time believing that they flicker because I can literally unscrew the bulb and watch it dim gradually over the course of a second. Which indicates to me that there's a capacitor in front of the LED drivers smoothing the current out. (Which I guess is required to be compatible with triac dimmers anyway.)

Huh, through experience with (mostly non-premium) LED bulbs, I've learned to interpret "gradually dims over the course of a second" an an early indicator of imminent bulb failure.
Never tried those, but speaking about flicker, some LED lamps flicker not because of the mains frequency (50/60 Hz depending on where you live) but because of their internal switching power supplies.
