I have gradually replaced every light bulb in my house since 2017 with Philips Hue bulbs (most color, but some white only) and not one of them has flickered, become more dim, or failed. On the other hand, the "cheap $10" LED bulbs that I originally installed when first moving in - because I could not afford $50 a bulb - have all died and were part of my motivation for upgrading to Hue. This has also happened with the cheaper LED bulbs that my mother and in-laws installed, which lasted about a year. I wonder why the Hue bulbs last so much longer? They have been well worth the money and have become a staple of my home automation.
