Crime, immigration, and “wokeness”: check. On inflation, Josh, I agree with your assessment of the headwinds Trump faces, but history has shown that he doesn’t need results to maintain popularity with his base; he only needs someone other than himself to blame for his failures.
My bet is on DOGE and Trump's incompetent and vindictive appointees causing parts of the federal government to collapse with catastrophic results.
However, if Trump really brings back real light bulbs, I'll buy a MAGA hat. I like that LEDs last longer and are cooler, but few of them meet 95 CRI, and those that do don't work as well.
I still prefer LEDs to traditional incandescents (in most applications, but not all), and they're both SOOO much better than CFLs. But, it's frustrating how the lifespan of LEDs is not nearly as reliable as the packaging claims, and varies a lot by manufacturer, usually due to shorcuts taken on the electronic driver circuitry and heat dissipation. It's meaningless if the LED chip lasts 50,000 hours, but the power supply dies after 10,000 hours.
Which is my main beef with so much of modern consumer good design, often driven by energy standards: the longevity and total lifecycle environmental impact is not adequately captured. If an appliance uses 20% less electricity, but lasts half as long as the design it replaced, you have to factor in the doubled rate of manufacturing emissions and environmental impact of disposal. There are some applications where there are beneficial tradeoffs to higher energy consumption that have a net environmental benefit due to the longer life (like heat exchangers in furnaces).
Thanks for this clear explanation! What about the problem of flicker? Why do many LEDs do that?
Another beef I have with LEDs is that many of them have an opaque collar between the upper part of the bulb and the socket. If you put them in the usual floor or table lamp where the bulb is pointing up, most of the light is directed up toward the ceiling and you get less light below than before. It's so frustrating.
Cheap LEDs with drivers that don't provide a steady power for the LED emitter flicker, but well-designed and constructed bulbs will have drivers that don't do this. But, it's more expensive to provide the driver circuitry and components, and not an obvious difference when comparing them in the store, so the cheaper flickering models proliferate.

Lawless disregard for the Fourteenth Amendment: check.
Guess he’s not that clever. We’ll see what happens on February 1st.
