Why the Lightbulb Conspiracy Theory Gets the Science Wrong
You have been mislead about lightbulbs
The story that manufacturers colluded to shorten lightbulb lifespans ignores a fundamental trade-off: longer-lasting filaments are dimmer and less efficient. I explain why the Phoebus cartel standardized lifespans to prevent a race to the bottom in product quality, noting that modern technology like LED finally broke this physical limitation.
Reality rarely fits into nice stories; even something so obvious like products designed to break are bad often isn't.

BTW, I don't understand why having the driver converting AC to DC inside the LED spots is the default. For a new house, it seems to make sense to me to have at least one external driver for a ceiling of spots, if not one per floor (not one for the whole house because pf the drop in voltage). But 24V led spots seem much less common and I cannot find many reviews.
Any idea why it's not more common ? It seems efficiency and thermals would be much easier to optimize without the size constraint, plus economy of scale with components.
Any specific 24V led spots / bulbs to recommend ?

I've never had LED lights last anywhere near the purported 5-7 year timeframe. The worst ones are the small decorative ones with the tinier screw part that my house seems to have an inordinate number of. Those last maybe 6 months and then they start getting dimmer and then all the lights in the circuit get worse at once. I like LED lights immensely but the idea they last even 2 years is a lie in my opinion.

That top paragraph is a masterclass in modern media standards. Tell the truth will hiding facts so your readers can be reassured that they are in fact smart and correct, while you never have to tell a lie.
