Interestingly, the latest generation of LED lights are so efficient that it makes little financial sense to bother having a light switch. 330 lumens per watt from recent Phillips bulbs!
The cost of having an electrician wire that switch is probably more than a little 2.5 watt light will use in it's lifespan - particularly when you account for the fact lights in hallways are probably in use most of the time anyway.
Add in the effort of switching the light switch a few times a day for many years and it's certainly the case! Or the risk of fumbling in the dark for a light switch at the far end of a room or in a house you aren't familiar with.
Obviously you might still want to turn it off for maintenance, but you have the breaker for that.
- zahlman 8mo agoWhat if you want to turn it off to have darkness?
- cogman10 8mo agoDo you have a link to the 300 lumens per watt lighting? I'm curious. I think that mostly only applies bulbs without inverters.

They do have smoothing capacitors so they don't flicker, and I think a slight redesign of the drive circuitry could add ~10% more efficiency...
- cogman10 8mo agoWhich of these bulbs? The highest efficiency I'm seeing poking around is 230L/W (Don't get me wrong, still very impressive)
