Smart lights: New LED lights with sensors raise privacy concerns
 
Viele Dörfer und Städte setzen auf LED-Beleuchtung. Das ist billig, aber oft - aus Sicht von Medizinern und Umweltschützern - zu hell. Franz Hölker forscht zu Lichtverschmutzung und erklärt, wie es besser gehen könnte.

While I was never a fan of the #fluorescent tubes in my office, the #LED lights that are replacing them are far worse. Not only are the new lights much harder on my eyes, the light they emit has this gross green tinge.

What Happened to the 100,000-Hour LED Bulbs?



Early adopters of LED lighting will remember 50,000 hour or even 100,000 hour lifetime ratings printed on the box. But during a recent trip to the hardware store the longest advertised lifetime I found was 25,000 hours. Others claimed only 7,500 or 15,000 hours. And yes, these are brand-name bulbs from Cree and GE.

So, what happened to those 100,000 hour residential LED bulbs? Were the initial estimates just over-optimistic? Was it all marketing hype? Or, did we not know enough about LED aging to predict the true useful life of a bulb?

I put these questions to the test. Join me after the break for some background on the light bulb cartel from the days of incandescent bulbs (not a joke, a cartel controlled the life of your bulbs), and for the destruction of some modern LED bulbs to see why the lifetimes are clocking in a lot lower than the original wave of LED replacements.
Interesting and thorough piece. The conclusion is not entirely surprising though.

Got some more automation working today! Radar based motion sensor, temp/humidity/pressure sensor, mosfet to control the under cabinet lights, and ESP32 for a bluetooth beacon and WiFi mqtt controller. Hooked it into my homeassistant instance set to bring up the lights to 100% when motion is sensed and down to 30% after there's been motion for 5 minutes. Testing everything out so I'm ready for the final version when we remodel.

Late to the party


I can’t believe it’s taken me literally decades to discover I love #Soundgarden. Of course I was always aware of “Black Hole Sun”, since it seemed like everyone covered it, but for some reason I never took to #grunge when it exploded, despite the fact that I was into #punk #rock in the early 1980s, followed by #heavy #metal. Maybe my tumultuous 30s messed with my ability to enjoy anything.

One good thing about discovering #music this late in life is I know I truly #love it rather than merely reacting to #industry #marketing #pressure.

Soundgarden: the band #Led #Zeppelin could have been had they been much better. (I know, that’s sacrilege to many.)

Side note: At about the same time, I discovered #Elliott #Smith. (This has been an exciting couple of months for me.)
