In physics, low voltage means low electricity consumption. low voltage outdoor lighting thus consumes lesser amount of electricity and so they would not make your electric bills rise up to the sky. This low voltage outdoor lighting is made with low voltage so that they will be safe to use in the outdoors such as in your backyard, on the lawn or even in the swimming pool dipped into the water. So even when they become wet, electrocution should be far away from your mind as they are safe. Even if open wires will be seen on the lawn, they will not cause electrocution either.
