    That was a great read, thanks. It made me realise I don’t even remember the last time I changed a light bulb!

      I wish I could say the same. I have had one of two that had circuits that burned out. One was cheap and not surprising. The other was a Hue. Speaking of Hues, mine all seemed to stop working with Google Home and one even decided it would permanently be disco time and continually flashes. Zigbee compatible bulbs only from now on for me.

        The leds can work for like 20 years. On the other hand the rest of the components are not necessarily going to last that long unfortunately.

      I’ve changed my fair share of LED bulbs. Nowhere near the frequency of incandescent though.
