Best Solar Flood Lights – Reviews

To find the best solar flood lights we reviewed over 30 different brands and models. These ranged from cheaper budget lights through to expensive premium-priced lights.

1. Sunbonar Solar Flood Lights

The Sunbonar the best solar security flood lights and is very versatile as you can install them in several ways, for example:

  • To illuminate large areas, you can mount the Sunbonar flood light high up. Perhaps on a wall or post.
  • The Sunbonar lights also come with two ground spikes so you can place them on your lawn. Use them to illuminate walkways and light up garden features.
  • To light up pool areas or tennis courts you can mount onto a fence.

Sunbonar’s solar panel and light are connected via a 16.4ft cable. This means you’re able to place the solar panel away from the light, optimizing solar energy while lighting the exact area you want lit.

When purchasing there is the option to buy with or without motion sensors. Personally, it would be recommended to buy the lights with motion detection as they’re more intelligent in operation so last longer per charge. The lights with motion sensors light at 30% power until they detect motion when they light fully, maximizing charge utilization. The sensor detects with a 120-degree vision and detects between 16.4-23.3ft.

The non-motion sensor lights are controlled via the on-off switch located on the light, this really isn’t practicable if mounted high up. It’s only advisable to buy the non-motion sensor light if you have easy access to the light or if you want the light to come on each night once dark. Lighting times will vary depending on the geographical location. Once light levels drop below a certain level the solar flood lights will automatically turn on.

Best Solar Flood Light Buyers Guide

What Area do You Want to Illuminate?

The most important aspect to consider when buying a solar security floodlight is what area it needs to light up. This will help you select the correct solar flood light you need according to the following:

There are many solar flood light applications meant for specific areas of a building. But manufacturers are developing floodlights that are versatile and can be used anywhere. So what area do you need to illuminate and what are the differences in each application? Let’s find out.

Backyard, Patios and Garden

Some people have large properties. The bigger your yard, the more difficult it will be to see beyond a certain point when it’s dark. Having garden accessories such as fountains or statues can also make it difficult to scan your garden or back yard for threats. 

You can use solar floodlights to illuminate your entire yard at night. The brighter the light the more potential the product has to eliminate casted shadows from trees and walls. This will make it easier for you to check the area. 

Driveways, Garages, Parking Lots or Walkways

Using LED solar lights is perfect for larger areas such as parking lots. Business owners with parking lots need brighter lights for larger areas to help people find their cars at night. It’s also a safety measure so people can see where they’re walking. Additionally, this is especially important for protecting business from thieves and potentially lowering insurance costs.

LED solar flood lights can also be used for confined spaces such as driveways. The brightness won’t need to be as intense but potentially requires wider lighting angles depending on light positioning (height and directional). The lower the height of the light fixture the wider angle required.

Rural Areas or buildings with No Electricity

There are some communities that have no electricity or it is to expensive to run electricity to a property. This can be a safety hazard at night especially for cars driving around the area at sundown. Solar powered flood lights can be used in certain rural places to illuminate hazardous areas such as the following: 

Your Front Door

Placing a solar LED light above your front door is an added security measure. If you receive a knock at the door late at night, you’ll be able to see exactly who it is. It’s also best to pair your front door solar light with motion sensors. The lights will turn on immediately when the motion sensors detect any movement by your front door.  Lights to illuminate your front door are very handy when trying to unlock the door at night. These lights do not want to be as bright as most solar flood lights as this can daze yourself and others.

Different Parts of a Building or House

People with large properties such as a big house or a company use solar LED floodlights to illuminate dark areas. These dark areas can be behind bushes, trees, between narrow walls, behind statues or water fountains among others. 

Premium bright LED solar flood lights can be positioned anywhere around large properties to light up these dark areas. 

What Type of Solar Light Do you Need?

There are six different types of solar floodlights used for various purposes. As mentioned before the type of product you select will determine what specifications you need to light up an area. 

Security Flood Lights

Security floodlights are probably the most popular solar-powered lights. This is because security floodlights usually have a motion sensor integrated into the product. The motion sensor detects any movement at night which immediately switches the floodlights on. 

Having security lights with motion sensors saves on energy consumption as the solar lights aren’t on throughout the evening. The lights only switch on when there’s movement so the charge will last longer and brightness can be more intense. 

Security floodlights also tend to be brighter than any other solar floodlight. They need to maximize the area illuminated around your property, meaning that you see if there are any potential threats. 

Some security solar floodlights have settings that allow you to adjust the following:

Security floodlights are more convenient because they inform you when there’s any movement in the yard. Having the lights on all night can also be beneficial but you won’t know if there are any potential threats unless you look for them yourself. Additionally, having lights on all night increases light pollution and may be an annoyance to you and others.

Flood Lights Without Motion Sensor

Solar flood lights without motion sensors are used in extremely dark environments needing constant light. As these lights need to run throughout the night larger capacity solar panels and batteries are required.

All-in-One Fixture

Some solar lights have panels that are remote to the lights, optimizing sunlight hours, and energy stored. All-in-one fixture solar floodlights have the solar unit and motion sensor manufactured with all the parts integrated inside the device; this means they can’t be detached from the light fixture. 

The only disadvantage of these lights is you can’t place the solar panel where there’s the most sunlight. The motion sensor isn’t detachable so the lights have to focus on this area. But the advantage is the lights are easier to install, can be more robust, and less susceptible to damage. 

External Solar Panel

External solar panel lights are different from the all-in-one fixture because the parts come separately. The solar panel is positioned for maximum sunlight conversion, while lights are focused to illuminate a specific area. 

The external solar panel can be a bit trickier to install, but they’re better valued for money as the lights will charge more throughout the day and provide enough light for the evenings. External solar panel powered floodlights are the same as security applications as it has motion sensors and they’re brighter than most products. 

Landscape Solar Flood Lights

Landscape solar floodlights are positioned high, illuminating large sections of land. This type of lighting is around the same brightness as security floodlights. They’re mostly used to stay on throughout the night, but can be integrated with motion sensors.

Usually, landscape floodlights are for lighting the following:

You can install landscape floodlights under roofs or higher up on a wall so it can light up more ground space. 

Hybrid Flood Lights

Hybrid floodlights are manufactured with a solar panel and mains electrical wiring. When the batteries run out of power mains power takes over control.

Brightness of Solar Flood Lights

Before purchasing your solar floodlights, you should check to see how many lumens (a measurement of visible light) your product produces. You can get lights that cover a small area around 300 lumens, or you can purchase a product that’s bright enough to light up a larger area 800 lumen plus. The larger the area the brighter and typically wider angled the light needs to be.

If you’re looking to light up a small dark corner of your yard, then you’ll need a light that has fewer lumens. It all depends on how dark the environment is and how much brightness you need to illuminate the area. 

Battery Types for Solar Flood Lights

There are four types of batteries used to power solar floodlights, they are:

LifeP04 and lead-acid batteries are found in the expensive and industrial solar floodlight brands, these applications are larger and last longer. 

In smaller applications, Ni-Cd and Ni-MH batteries are used as they require less power and capacity. Smaller lights are used for illuminating areas such as garage doors, front gates, or areas with security cameras.

Typically, you’ll find solar lights use lithium iron as they have the perfect characteristics for charging and discharging while having a good lifespan too.


As you can see there are different types, sizes, and functions of each reviewed solar floodlight. To select the product that fits your needs you simply need to look at the size of the area you want to illuminate and how much energy you’d like to save. 

The products that have adjustable settings and remote control access will definitely make it more convenient for you to control your solar floodlights. 

Solar flood lights are practical, easy to install and they’re cost-effective. Install solar flood lights if you’re looking to provide extra security around your home or business and save on energy at the same time.
