| Don’t bother turning off the lights when you leave a room |
| Generations of children and spouses had it drilled into them to turn off the lights when they leave a room, whether to preserve the lifespan of the bulb, reduce the energy bill, or … both? Here’s what Wirecutter experts say: The practice may have held merit for incandescent bulbs, which were terribly inefficient. But modern bulbs use so little energy that leaving them on doesn’t make a meaningful difference on bills. And, depending on the bulb, turning them off regularly won’t affect their lifespan, either. So don’t worry about flipping that switch on your way out. |
