J J Jameson asked: Solar powered lights for home gardens have come along way. They used to be unreliable because they broke down easily and only turned on for a few hours before needing to recharge. But in the past few years, the technology behind solar powered lights has improved greatly and solar powered lights has become one of the best way to decorate the exterior of homes. Great thing is they also save money at the same time. There is nothing more mesmerizing than colorful display of lights on a house in the dark of night. Still, when in the market for solar powered garden lights, it is best to first understand how they work. First of all, they are not like the familiar electric lights we use in our kitchen. Solar power lights do not use electricity or battery. So they attract many homeowners who want to be decorative and, at the same time, save money. But, one thing to keep in mind is that they rely on optimum placement in the garden to work properly. Solar powered outdoor lights use solar panels to absorb sunlight in the daytime. The panels are connected to solar cells that turn the sunlight into energy which is then stored in a battery. At night, the battery powers the bulb until energy is used up. The cycle repeats the next day so that light is available at night. The great advantage of a solar powered garden light is that it never needs any electricity. Using solar powered lighting is simple, but there are a few small pointers to understand. For example, in order to receive full performance, there must enough exposure to direct sunlight in order to charge the battery. Now, some solar powered garden lights can recharge using any daylight including during cloudy days. But having direct sunlight is the best source. This means that in most places of the world, a solar powered garden light will perform better during summer than in the winter. And that’s just normal. Also, by it’s nature, a solar power bulb is not as powerful as a typical 60 watt bulb. So lighting may seem dim when compared to traditional light. But it’s enough for some purpose, such as pathway or driveway lighting and evening garden decor. It is best to use as many solar lights as possible since these do not use electricity. The more lights, the better. Additionally, a solar powered LED light might be a better pick than non-LED light because it is brighter. To summarize, solar powered lights are fantastic for low light duties such as pathway lighting, accenting garden floral arrangements, or mood lighting. They don’t use electricity and can save money in the long term. If the need for light is for reading or other activities requiring brightness, then it’s better to use the traditional light bulbs
