Solar lights operate by capturing the sunlight during the day and converting it into an electrical current. This current is stored and acts to power the lights overnight.
Solar lights have a solar panel (or photovoltaic panel) which collects and converts the energy from the sun. The preinstalled rechargeable Ni-Cad battery stores this energy. A LED (or light emitting diode) bulb is used as the source of illumination. Many solar lights also have a photocell sensor which acts to turn the solar lights on or off depending on the amount of available sunlight.
What is the main difference between solar lights and landscape lights.
The first difference between solar lights and landscape lights is that solar lights are powered by the sun. Landscape lights are powered by 12 volt electricity. To enhance the brightness of solar lights, LED bulbs are usually used. Halogen was commonplace sometime back but manufacturers are using LED bulbs more and more. The main reason for this is that LED lights emit light but not heat so no energy is wasted. One LED bulb emits roughly the same brightness as a 2 watt light bulb.
Should I choose solar lights or landscape lights?
It is necessary to consider what you need the lights for and where you intend on installing them. If you are needing safety and security, then you would need lights that are always on. In such an instance, solar lights may not be the best choice because they are limited to the power which is stored in their batteries. Electrical landscape lights are also brighter than solar lights which should be considered for security lighting.
If you are looking for accent lighting for highlighting areas such as pools, ponds, trees, garden beds or other landscape features then solar lights are a great option.
How long do solar lights operate for?
The length of time that solar lights operate depends on the size of the solar panel and the battery. Solar lights will emit light for 8-10 hours per night.
What is the brightness of solar lights?
Solar lights are not as bright as electrical landscape lights. The LED bulb casts a different type of light. If brightness is an important factor, keep an eye out for solar lights that have more than one LED bulb. Accent landscape lights around a pool or outdoor table may only need one LED bulb but path lighting may need greater brightness for safety reasons.
How long do the solar lights LED bulbs last?
LED bulbs are built to never burn out throughout their lifespan. This lifespan is usually around 25 years. LED bulbs within the solar lights, themselves, cannot be replaced.
How long do the solar rechargeable batteries last?
The inbuilt Ni-Cad (nickel-cadmium) batteries are meant to be used from fully charged to fully discharged. These batteries typically last for at least 1000 years but are simple to replace at that stage.
With the great pressures on fossil fuels, solar lights are becoming a popular choice for gardeners and landscape deigners alike.
