The thing about light bulbs is true. The cartel imposes penalties if light bulbs last long. It seems that they put lesser tungsten then before. I figured out the problem with incandescent light bulbs, in my school days. Example I found that 100 w bulb with reduced voltage to give 60 w would last forever. That's what I do with my table lamps. I just use a fan regulator and I have bulbs going strong for 30 years till now. My soldering iron (labeled Tony) is from my school days from the 80s.

Yes. This is what I do with my table lampsView attachment 89687
something like this ?
I use to reduce the table fan speed further , or the brightness of table lamp when needed.
unfortunately, the Fan gave up after about 10+ years( could be couple of years on this regulator ).
If your bulb is incandescent lamp then its a resistive load. Modern fan regulators are typically designed for an Inductive load and so the regulators may have a capacitor across the voltage drop resistor to keep the current leading the voltage to adjust for the Inductive load of the motor windings.View attachment 89687

Fan regulators use triac and works perfectly for resistive loads. I have been using them since the 80s for my table lamp bulbs and my soldering iron. They will not work for tube lights and most led bulbs.If your bulb is incandescent lamp then its a resistive load.

The LED driver is the weak point. They fail quite often. Some go totally dead and few start blinking every few seconds. I have had atleast 3 Eveready led bulbs fail in the last 3 years and 2 led tubelights fail. Plenty of my false ceiling lights have failed till now because of the inbuilt led driver. For the led based tubelights, the drivers can be easily obtained in any electrical store. One just have to open the led tube light from the sides and pull out the led strip. Then desolder the led driver and solder a new one. Not something a normal person will do. So the led tube lights are repairable but I haven't found a solution for the bulbs other than harvesting the individual SMD leds from failed led bulbs to use them in my various DIY projects as power indicators. None of my Syska led bulbs have failed till now.In general, planned obsolescence is pattern we see in the modern consumer products. There are brands like Patagonia which are against this practice. They encourage customers to keep wearing them for a life time and make lasting memories. They even have a mobile repair service for torn clothes which mean a lot to their customers.
Having said that, this is not be taken as a blanket statement that new products are all cheap and unreliable. Isn’t the modern technology of LED more long lasting than incandescent bulb? With the kind of power infrastructure we have, those filaments are prone to failure.
While there is chance that LED fail due to poor quality or workmanship, in general they last longer. LEDs typically last anywhere from 25,000 to 50,000 hours, whereas incandescent bulbs usually only last about 1,000 hours. My experience has been that they rarely fail. Even if they may grow dimmer through time, this surpasses the incandescent bulb by a large measure.The LED driver is the weak point. They fail quite often.

Though the individual LEDS may last long but they start loosing intesity as time passes by.
Ok. My fan regulators has resistors and capacitor hence my reply.Fan regulators use triac and works perfectly for resistive loads. I have been using them since the 80s for my table lamp bulbs and my soldering iron. They will not work for tube lights and most led bulbs.
