try getting rid of them now. you can;t throw them in the trash , nor in the recycle bin. you have to give them with the dangerous goods.

Its the same pattern with many things. CO2 is bad? Let's go for diesel cars. Oh no, NO2 is bad, lets punish all those diesel car owners who bought to be environmentally friendly. Who gives a damn this week about CO2? That's so last week..... and next week. Its just not this week.

It's worse with refrigerants. Ammonia was toxic and smelly so they switched to R12. R12 was wrecking the ozone so they banned it and switched to R22 and R134. R22 has some ozone depletion potential (5% of $12) so they phased that out and switched to R410. R410 and R134 are greenhouse gasses so they're working on phasing those out. Each time of course requires new equipment and new tools to work with the stuff. IMHO we should have stuck with R22 and R134 and just focused on capturing and recycling it to avoid letting it out into the atmosphere.

Indeed, later research may well have proven those conclusions, & my comments, to be wrong, but isn't the onus on you to give some examples of how "much more complex" it is.

"Because you say so" just doesn't hack it!

How about "because I can see the pixels with my own eyes"? Does that count? I tend to believe something when I can see it myself.

You make that sound like a good thing. However little power it gives us, we can vote out a politician. The technocrats can only removed through serious violence.

Well, we do not get to vote for the EU president or for the EU comission, actually.

I had some early failures but I also had many that lasted longer than the rated life, largely that came down to how rarely they were started. Lights that came on once in the evening and shut off later lasted much longer than those that were switched off and on often.

I've seen National CFLs run for 10 years in stair wells, where they were never turned off. I think they were only rated for 8000 to 10000 hours, but could massively exceed that. Most of the complaints about the short life of CFLs  are due to many warm up cycles (e.g. bathroom use) or use in an enclosed luminaire. Most CFLs are marked as unsuitable for use in enclosed fittings, but people ignore that. They blacken even faster when they can't dissipate their heat well, than when they are turned on and off a lot.

I think I once got around 12k hours out of one that was rated for 8,000, it was in a light on my desk at work that was left on all the time. It's not too hard to make one that will keep going longer than that, but the phosphor is going to get pretty tired at some point. L70 is considered EOL.
