Regular light bulbs, your days are numbered. That's because cheaper, more efficient LEDs are here to make lighting a much more attractive affair. Just take a look at these LED spotlights.
They stick on whatever surface you want and run on batteries. Due to the efficiency of LEDs, they very rarely need to be changed, and they're turned on by simply pressing on them. They're the perfect lights for in the kitchen, the bathroom, along the stairs, or anywhere else that you need a small light without running a cord around the room.
