Improve House Security
Dusk to dawn sensor LED bulbs are particularly useful for outside/indoors lights.
When you're away from your house, they come on/shut off automatically.
You don't have to think about turning the porch lights on at night anymore!
No more running down the stairs to turn on outside lights!
You don't have to remember to turn lights off in the morning anymore!
They go on at dusk and off at dawn, which means some savings on electric bill.
