- pouetpouet 9y agoPerception of brightness is not linear. The human eye response is not linear. So x10 the luminous flux (power output) will be perceived as brighter but far from x10.
- Dylan16807 9y agok. People are still not installing 10x as much light.
- pouetpouet 9y agonot in their home, but I can see many more historical and institutionnal buildings being illuminated, commercial use also. It may still not amount to 10x though.

- user5994461 9y agoOffices and shops used neon lights. It lits as well as LED or better, but consumes a lot of power.
- pfdietz 9y agoDo you mean fluorescent bulbs? They do not use neon, but rather use mercury vapor. The UV light from the mercury excites a fluorescent layer on the inside of the tube, causing broadband emission of visible light.
