I remember having the light-measured-in-watts discussion years ago when LED lights were still considered a novelty. Of course, this was with a videographer who actually understood the issue. He complained that it wasn’t a good idea to limit car headlights based on their wattage, which is how all the laws at the time were written. 5 years later, suddenly there were LED headlights blinding everyone.

I actually like the compatible watts for light bulbs. They should absolutely also prominently list a correct measurement (I assume linens?), but I only know how bright it is based on the old watt comparison.

Just like crop frame cameras list lens lengths in full frame equivalent because that is what people understand. But they also need to lose the actual mm.

Stopped reading after: “increase in battery capacity and charge time was achieved through a “brand-new superconducting electrolyte formula” that results in improved conductivity.”

I guess the source, author or both don’t really care about technically accurate terminology. If it’s good enough for Star Trek, it’s good enough for us.

So should we use Foot candles or Lux?
