They have issues working together. It was hard, but I finally was able to reach the manufactures. Each one told me to return them. They had no solution to the problem. They didn't care that they didn't work. Their solution was simply to return the junk where I bought them. --- End quote --- Caveat emptor. We have a couple online shops selling cheap self branded cheap LED bulbs together with self branded dimmers. I bought GU10s from one of those, a one stop shop is useful, with EU online purchasing laws they are incentivized to make it work. I won't get the best lumen per watt or longevity most likely, but it just werks. GU10 sucks for longevity, but retrofits are a compromise. I wouldn't be surprised if Apple jumps in and just start selling their own bulbs and dimmers ... and it will just werk as well (at 10 times the cost). |

--- Quote from: Kjelt on August 08, 2023, 06:43:49 pm ---Indeed ac dimming is and has always been a PITA for led lighting. --- End quote --- Trailing edge dimmers were such a wasted opportunity. They should have made it an industry standard "for trailing edge, 90 degrees conduction angle is minimum brightness". Expensive dimmable lamps could have been made compatible with all dimmers, cheap ones would have been trailing edge only and still always have full mains voltage behind the rectifier. |

| Microdoser:
I have no problem dimming my LED lights (to a point, any LED light has a minimum working voltage, like a diode funnilly enough). I just use a current limiting power supply and limit the current to them, I can easily get their power usage down to 15% of the rated value with no discernable flicker (much less than that if you don't mind flickery lights) Of course, this is only a solution for people who know the right end of a soldering iron to use. It seems that is not everyone here... |

The problem is ripping up the walls and ceiling, not the soldering. |
