If you need outdoor lighting, and a simple fixture right next to your door just isn’t enough, then you might want to consider solar lights. There are many pros and cons, but if you can accept their flaws they are certainly convenient and will last you a long time.
How Solar Lights Work
Solar lights work much like solar-powered calculators. In order to do this, they have two layers of silicon placed between a conductive coating and a light absorbing coating. One of these layers is left with impurities so that electrons from the sun’s rays attach themselves to it, and when all the impurities are filled, extra electrons are carried to a battery for later use.
Cons: Energy
If this seems like an overly complicated process, it is. This is reflected in the poor efficiency. A solar light has to be placed in an area that is well-lit during the day, or it will not have enough power to do its job when called on. This means no putting them directly under bushes or trees. Even with ideal placement, they will also be affected by rainy or cloudy days.
Pros: Convenience, Longevity
Once you do find a good area for a solar light, though, you can basically forget about them for years while they do their job. They use LEDs, which are exceptionally long-lasting: some types can last for 100,000 hours, or more than 11 years of continuous use. They might outlast things inside your home, like your bathroom lighting. Cords are also unnecessary, which is vital if you want an attractive setup on the way to your door. Nobody wants cords running to each of a dozen path lights, which would not only be ugly but present a tripping hazard.
Cons: Cost
Solar lights can cost twice as much as equivalent setup using cords. However, lighting is a relatively inexpensive feature of the home, and their longevity, convenience, and attractiveness may still make them a better option for you.
