LED lighting and planned obsolescence, intentional or not.
NiHaoMike:
Apart from the LED lights dimmable using a dimmer, there are also ones dimmable by remote controls and ones dimmable by IoT. The IoT ones have their own problems, of course, but many of them can be solved with Tasmota. https://templates.blakadder.com/light.html

Earlier I reported being gifted 2 faulty fixtures and that their drivers could be configured for output current so I grabbed the resistor config table from the datasheet, as attached.
Recently we needed to replace a 30+ yr old 60" single fluorescent as its end caps would no longer make reliable contact with the tube pins. :horse:
Its replacement was a very similar fixure but configurable LED with 2 brightness settings and 3 white settings with a 3 position sliding switch.
After some weeks mucking with it to find good for us settings the medium white, 4000k IIRC and 30 instead of 50W were selected.
One asks oneself why all these adjustable setting were added to a relatively cheap fitting......so it could be configured for an extended lifetime ? Of that we will see.

running at a reduced voltage can help, 10 or 11 volts on a lighting strip not 12.

Yep, it helps a lot. Due to the temp vs longevity curve for most components.

You mean a lighting strip that uses fixed resistors to limit the current, with no electronics to control the current?
