I have a couple of dimmable, but non-colored, IKEA lights. I have learned that the proper way to factory reset them is to turn them off and on again 6 times quickly. That worked for Trådfri lights I had of a different model.
However, when I do this to these non-colored lights, they don't reset. I noticed that they don't seem to go out fully if I do it too quickly (unlike the other models), but neither waiting for them to light up and dim out fully nor ignoring that and just doing it quickly worked. What should I do?
