> It’s funny because incandescent three-way bulbs and switches used to be very common. Now that everything is LED you need a complicated timer system to achieve the same result.
Or just a dimmable LED bulb in an existing 3-way fixture.
>>dragon+(OP)
Dimmable bulbs and 3-way lamps are not compatible: https://en.m.wikipedia.org/wiki/3-way_lamp. The electrical principles are not the same —- a three way bulb has a different socket contact configuration to accept different wattages at each of the three levels. Supposedly LED 3 way bulbs exist but I’ve never seen one in the wild.
