Garden lights offer the ability to illuminate your garden and garden decor in an almost magical way, creating faux shadows, elegant backdrops, all the while highlighting the best parts of the garden for all to see.
Beyond this wonderful use of garden lighting, there are actually a few practical reasons to consider using them, even if you aren't the garden type or consider yourself artistically inclined to set up such a thing.
What practical reasons am I talking about?
Safety! I mean this in two ways.
First, safety in the sense of providing light in areas where it might be dangerous or risky to move about if there were no light. This includes obviously the garden but also areas where garden lighting accessories or outdoor lighting accessories have become extremely useful; namely, stair lighting! Attaching solar powered stair lights is a brilliant idea. And even just having walkways and pathways in the yard lit up is going to make it easier and safer to walk around.
The other type of safety that garden lights provide is a deterrent for theft and burglary. Simply put, if your yard and things are lit up then you are less likely to find yourself the victim of a thief, who would just as well find it easier to move on to the next house that is shield in darkness. Of course, garden lighting is not a security plan in and of itself, but knowing that it acts a potential deterrent is a nice perk of a good lighting set up.
Another practical use of outdoor and garden lights is just so one can see in order to do other things when it's dark. This sounds silly, but I'm talking about things like hosting outdoor parties, reading outside, even being able to see little things such as where the keyhole is when you come in and you're trying to get inside. (This could be lit up by a garden in the front yard.)
So while garden lights of course offer the benefits of making for a beautiful garden set up, you also get the perks of having an outdoor area that's safer for kids and adults alike to move about and see where they're going, a home that's not as easy as a target for burglary than it would be without the lights, and then the practical aspect of having lights which offers you the chance to entertain outdoors at night or just relax and read a book in the garden.
