Product Information

Solar lights do not emit any greenhouse gases or other pollutants, making them an environmentally friendly lighting option. If they also have a motion sensor, they won’t contribute to light pollution, helping to reduce the impact on natural ecosystems. Yes, solar lights are designed to be weather resistant and can withstand a range of weather conditions. Most solar lights are made from durable materials, such as weather resistant plastic, stainless steel, or aluminium, and are designed to withstand exposure to rain, snow, and other environmental factors. To help you find the best option for all of your outdoor spaces, we tested 27 different solar lights at The Lab in Des Moines, Iowa, including path lights, spotlights, lanterns, wall-mounted, and string lights. Each light was evaluated for its ease of assembly, brightness, features, design, value, and durability. For example, after assembly, we froze them and dropped golf balls on their solar panels to see how they would withstand the elements, and read under them to test their brightness. We even video-recorded them overnight to make sure they truly stayed on from dusk until dawn! We also tested and installed 18 wall-mounted lights on our own homes, and recorded their brightness and durability through changing weather conditions.

Outdoor solar lights fall into three general types based on their light output: motion-activated, dusk-to-dawn, and timer-controlled. Because of solar cell size and battery capacity, the gathered solar energy is a limited resource, so consider when you want the lights to shine and for how long. Timer-controlled solar lights give you the most control since you can specify the time they turn on and for how long. Its IP65 rating means it is a water resistant solar light option. We observed no damage to either the light or the solar panel when we subjected them to water and golf ball tests. Post-freezer, the lights still worked as well. Ultimately, we found these to be a good deal for their price and practicality. They've also survived every other durability test we've thrown at them, including sharp tugs of the wires, a deep freeze at -16°C, repeated soakings and lots of bashing against a fence post. Solar-powered landscape lights can be used to make specific outdoor features such as trees, fountains, or statues look their best during the hours of darkness. Use a soft cloth or sponge to clean the light fixture, and avoid using any abrasive cleaners or scrubbers that may damage the surface.They'll still work on cloudy days or in areas with indirect light, but you might notice that they aren't quite as bright or long-lasting. "It is a fact that energy storage is much better if it's under direct sunlight, but solar lights can still work with rain or even snow," Jameson says.

The Ring Solar Pathlights provided incredibly bright light, and the system as a whole was quite durable. However, a Ring Bridge and a smartphone app are required to connect it to Alexa. We weren't able to get the app working properly during testing, which is why we didn't include it on our list of the best outdoor solar lights. If you have the time and patience to devote to setup—and you already own other Ring accessories—this could still be a great fit for your home.The solar string lights are meant to be durable with their shatterproof material and Brightech's WeatherTite technology. While no official waterproof rating is given, this technology is designed to help the lights handle 50 mile-per-hour winds along with rain and snow. They're also resistant to temperatures as hot as 122 degrees Fahrenheit. The bulbs are made of plastic, but one tester said they are "clear, pretty, and don't seem cheap." In general, the batteries in solar lights last between 1-2 years with continual use, and the LED bulbs can last more than 10 years, depending on the quality and usage. However, if the solar light is exposed to extreme weather conditions, such as excessive heat or cold, or if the battery is not maintained properly, the lifespan may be shortened.
