They’re pretty incredible, 200+ lumens per watt for LED lighting vs 16 lumens per watt for incandescent, 12.5x more efficient. Commercial LED fixtures have rated lifetimes of 50,000+ hours.

- toast0 5mo agoThe pain experienced by looking at bright source of light seems to be fairly effective?
- maxerickson 5mo agoI guess it's unlikely to be 12x, but people probably do consume more light, by way of being less worried about switching them off.

- toast0 5mo agoI try not to, on account of the pain.
- dredmorbius 5mo agoIt's less that individual light fixtures or applications become brighter than that more things are lit. Outdoor lighting 30 years ago used to be limited to, say, a porch light and perhaps a few motion-sensor floodlights near a garage or driveway, and those only on a handful of houses within a neighbourhood. Today it seems that the majority of homes in many locations have persistent outdoor lighting, whether along paths, gardens, or building peripheries. Holiday lighting is far more prevalent, and not strictly limited to Christmas and Halloween. I'd seen Easter lighting exhibits in recent years, as well as adverts for firms offering holiday lighting services. And that's just residences. Illuminated billboards, industrial lighting, street lighting, etc., are all both more prevalent and brighter than a few decades ago. A friend is on a campaign against a local business whose bright lights shine directly into their house all night.
