We have a Maestro Dimmer Macl 153-M with companion dimmer. Our home was built in 2018 and EcoSmart bulbs were installed. In 2022, a couple of bulbs burned out and I tried to replace them with approved EcoSmart bulbs. The new Eco-Smarts would flicker erratically when the bulbs were on full brightness. I tried a couple of other recommended bulbs. The ones that work the best are GE bulbs. I bought GE bulbs at Lowes LED9DR3015/G2L6 and they worked pretty well but not perfect--just an occasional flicker. I then put in GE bulbs from Target LED9 30 EG-4 and they work fine. The EcoSmart bulbs sold now look different and apparently have different circuitry. I do not know how Lutron tests their bulbs to put on their recommended list--perhaps everything is tested under perfect laboratory conditions. I have other neighbors with the same setup also having problems replacing them with EcoSmart bulbs. I hope this thread helps someone.
