So what we have are programmed obsolescence, consumerism and commercialism
I'm sure we've seen this one before......

This is the society in which we live.
LeghI don't find this BBC article convincing or appealing to an engineer. I don't doubt that there is a lamp that has been shining for over 100 years, but how many watts does it consume and how many lumens does it output? I'll not hold my breath for an answer to that one.
In general, with filament lamps, life and efficiency are traded against each other. BS 161, now obsolete, was the standard for GLS tungsten lamps, and various competing manufacurers tried to meet it. The 1000 hour life was a workable compromise between life and efficiency. Some uses bought lamps rated at 10 or 20 volts above actual supply rating, to gain extended life, but at the expense of light output and this could be shown to be a false economy unless replacement labour costs were high. Similar arguments could be brought against the 2000 hour "long-life" lamps that some makers produced.
We have moved on to compact source fluorescent lamps, which give both longer life and higher efficiency. Unfortunately they were not as popular as they should have been owing to poor marketing methods and ill-considered legistation to phase out tungsten lamps.
We have moved further to LED lamps. These are becoming widely accepted. It is not all bad news. This is real progress.
Don't assume that the manufacturer has your best interests at heart. The 1000 hour lifespan for GLS lamps was set by a cartel of manufacturers who wanted to ensure a constant stream of customers buying new lamps. Longer life lamps would have been slightly less efficient, but they were simply not offered to consumers for fear that the consumers might buy them.
The new LED lamps we get are also designed to fail. I'm a regular viewer of Big Clive's videos on YouTube. He recently featured the Philips Dubai range of LED lamps. As the name suggests, they are only offered for sale in Dubai, in return for a monopoly agreement from the local government. They are more efficient than the lamps that Philips offer over here, and they are designed to run cooler, so they will last longer. Of course they will cost a bit more, but it is telling that Philips will not even offer them outside the one country where they have made a special deal with the government.
I certainly do not think manufacturers have our best interests at heart. I have complained a few times on this forum about unhelpful labelling and inappropriate specifications.
I saw Big Clive's article on the Dubai lamp. I am afraid I don't understand how this monopoly agreement benefits either Dubai or Philips, (Explanation, anyone?) other than help Philips to sell off old and less-efficient stock. I think most consumers would be prepared to pay more for something that is longer lasting and more efficient.
And can Philips prevent its competitors from developing something equally efficient? Does it not want to sell more lamps itself?
