60 watts to illuminate just one room used to be the norm. Now it sounds insane. Maybe losing the perfect color rendering index was a worthwhile tradeoff after all.

Street lights use sodium-vapor fluorescence rather than incandescence, which was actually more efficient than LEDs until a few years ago (and I believe that low-pressure sodium-vapor still is and only high-pressure sodium-vapor has been surpassed by LED tech).

So there isn't all that much power freed in replacing existing street lights lamps with LED.

However that tech doesn't really work well for lower power application such as home use, hence why people used to have 60W incandescent lamps at home or their fluorescent lamp equivalent (which is around 20W) that were replaced by first 10W LEDs and now even lower as LED light bulb tech has improved.

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.

Here are some examples to inspire your own showerthoughts:

Rules

  1. All posts must be showerthoughts
  2. The entire showerthought must be in the title
  3. No politics
    • If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
    • A good place for politics is c/politicaldiscussion
  4. Posts must be original/unique
  5. Adhere to Lemmy's Code of Conduct and the TOS

If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.

Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.
