Solar Powered Flood Lights: Can Solar Generator Power Flood Lights

Stepping outside on a warm winter evening can turn into a horrible experience when you know the only thing that will greet you is darkness. Fumbling for a light button in the dark or navigating your way without tripping becomes tedious. Fortunately, solar-powered flood lights offer a simple and affordable solution for illuminating your outdoor spaces. It's an easy-to-use and powerful way to experience a new world of illumination.

The power consumed by solar floodlights will depend on their size and type. For instance, an LED flood light consumes nearly 6-8W, whereas incandescent light power consumption is around 50-150W. Jackery Solar Generators are designed to meet the different power needs of the user. With a battery capacity of 293Wh, Jackery Solar Generator 240 is capable of charging all types of flood lights for long hours.

What Is Solar Powered Flood Light?

Light sources powered by clean, safe, and pollution-free solar energy are termed solar-powered flood lights. They are widely used to illuminate tunnels, factories, landscapes, urban homes, airports, ports, highways, buildings, outdoor areas, etc.


Solar-powered flood lights consist of a solar panel and a rechargeable battery that works in tandem to supply charge.

During the day, the solar panels absorb sunlight and convert it into usable electricity. The rechargeable battery then stores the generated electricity to power the light source at night.

Besides, the system has a solar controller to protect the overall solar structure and ensure efficiency. It prevents the battery from overcharging and over-discharging. Furthermore, it protects the LED flood lights from instances like output short circuits and output open circuits.

How Does A Solar Powered Flood Light Work?

Solar photovoltaic panels absorb solar energy from the sun and convert it into electrical energy. Through the solar controller, the generated electricity is stored in a rechargeable battery.

At night, the light intensity from the sun and the panel's voltage decrease. At a specific voltage, the solar controller controls the battery charging by solar panels and allows current to charge the floodlights. The supply from the battery to the light source starts until dawn arrives.

There are four main working modes of solar LED flood lights, including:

Manual Working Mode: A remote controller lets you control the working of solar flood lights.

Dimming Working Mode: It is a time-controlled on/off method that automatically turns on the light at night and off during the morning.

Human Body Induction Dimming Mode: Integrated with body motion sensors, the dimming mode detects the human body movement and automatically adjusts the light to total power output when there is motion.

Constant Brightness Working Mode: In this mode, the light works with constant brightness continuously.

        Solar Powered Flood Lights FAQs

        What size of solar generator do I need to power a flood light?

        Calculating the size of the solar generator will depend on the watts and lumens required by flood lights.

        Let's say you want to power the LED flood lights that consume around 6-8 watts of power using Jackery Solar Generator 240 with a battery capacity 240Wh.

        Working Time = Capacity in Wh * 0.85 / Operating watts of lights

        Working Time = 240Wh * 0.85 / 6W = 34 hours.

        That means Jackery Solar Generator 240 will allow you to power a LED light bulb for 34 hours. If you use 5 LED lights of 6W each, you can power them for nearly 7 hours.

        Note: As there will be some loss of power while working, we multiply the capacity by 0.85.

        How many lumens do I need for the outdoor flood light?

        Lumens are the light output of the fixture that indicates the brightness of the light. The more the lumen rating, the higher the brightness of the solar flood light.

        • Small lights: 100 lumens
        • Motion-activated lights: 300-600 lumens
        • High-power outdoor lights: 1000-3000 lumens

          How long do solar floodlights last?

          The high-quality LED commercial-grade solar lights can last years, depending on the construction quality. However, the batteries in outdoor solar lights generally require replacement after 5-6 years.

          Are solar floodlights worth it?

          Though solar floodlights are a great addition to any home or outdoor space, they cannot match the capabilities of a solar generator. Jackery is one of the top sellers of solar generators, offering high-quality products at an affordable price. Not only can you power floodlights with the generator, but it is also a portable solution to charge other outdoor devices.

          Final Thoughts

          Solar appliances are taking over the market as they are a clean and renewable energy source. Even though solar-powered flood lights let you eliminate high electricity bills, low temperatures and short sunlight hours reduce their efficiency. In addition, they may not work effectively during bad weather.

          On the contrary, a powerful solar generator offers reliable energy for long hours. Jackery is the pioneer in selling different sizes and capacities of solar generators. For example, Jackery Solar Generator 500 can power a wide range of appliances, including floor lights, fans, mini coolers, etc.
