Well, now that you’ve made me think, I realize that I’ve never had a lamp of any kind that was ‘dimmable’, before this Ikea thing.
I’ve had some lamps that were ‘3-way’; but never one that dims.
And I haven’t used the 3-way lamps in years - they’re in storage, and I never used anything with them but 3-way incandescents.
But, how are THEY going to work with LEDs, when I pull them out now?
(Jeez; life has become so complicated...)
Many sellers have 3-way LED bulbs. Just search online.
I have a tech background and also really “got into” lighting design for a project when I was in college. Of course, some of the technology was a bit different, then!
Of course, if you want REALLY complicated, try running even a mildly complex small business and dealing with the Federal Tax Code!
Regular LEDs with a 3-way lamp are going to turn on and off with every other click: Two clicks full on, and two clicks full off.
There are 3-way LED bulbs, though I find sometimes the upper two ranges are too close together, so I had to hunt for ones that doubled for each higher setting.
