What is the Quality of Solar Floodlights?
The main points to evaluate the performance and quality of a solar flood light are brightness, sensing distance, lighting time, and life. ADN has also collected some screenshots of customer reviews on AMAZON; you can find out their main concerns.
Important Parameters Affect The Solar Led Flood Lights Quality
Like all solar lights, the main components that determine the quality of a solar-powered flood light are LEDs, batteries, and solar panels. Most controllers are of similar quality and will not be introduced in detail here. Let’s further discuss each of the following main components and discover how it affects solar-powered flood light’s overall efficiency and effectiveness.
LED: The Component That Determines The Brightness of The Solar Light
It is important to note that the number of LED chips is not the primary key in determining the brightness of the solar light. The lumen value, rather than the LED power, dictates the solar lamp’s brightness. The following equation can simplify it:
Lumen Value = Led Power x LED Light Efficiency
Therefore, when comparing the brightness of solar outdoor flood lights, look at the lumen value in the parameter table instead of just looking at the LED power. It is preferable to do so rather than merely comparing the number of LED chips. For solar flood lights, the small lumen value is only 200-300lm, and the high one can reach 4000lm to 5000lm. However, many 2C platforms are now also falsely labeling lumen values. Later in the article, we provide an in-depth technical explanation of this.
Battery Capacity and Solar Panel Power
Battery capacity and solar panel power are key parameters that determine the lighting time of lamps. The battery capacity parameter is AH, and the battery voltage is generally 3.2V (LiFePO4 lithium battery), 3.7V (LiMn2O4 lithium battery), and 12V (High quality for the project use).

The parameter of solar panel power is W, and the voltage of solar panels is generally 6V and 18V (High quality for the project use). The types of solar panels used in solar flood lights mainly include monocrystalline silicon solar panels and polycrystalline silicon solar panels.

False Mark Parameters
On Amazon, Shoppee, and other platforms, you can have a large selection of 100W to 500W solar flood lights. The lumen value of these floodlights is also marked as high. If you’re a little more professional and have experience in purchasing LED lights before you’ll know this. You’ll discover that LED floodlights cost substantially more than solar floodlights for the same amount of lumens and wattage. This is very unreasonable.
Unfortunately, the wattage and lumen values of these 100W to 500W solar floodlights are falsely labeled. Consider looking up the solar panel and battery specifications for these solar lights. In that case, you will find that the solar panel power and battery capacity can only support LED lights with a force of several watts to 5 watts for several hours.
So before you buy a solar flood light, you need to carefully check the solar panel power and battery capacity to get the lead’s actual power and lighting time. For additional details on the parameters of solar lamps, click here.

How to Repair a Solar Flood Light?
To begin with, if the solar floodlight is only on for a short time, you have to observe whether the solar panel has a shadow. Even a small area of shading can greatly reduce the charging power of a solar panel.
If the light’s indicator of solar light or the motion sensor does not light up, the solar flood light’s internal wiring is broken, or the light’s components are disconnected. The easiest way to repair a solar flood light is to replace the new solar light parts separately. After which part is returned, the solar light starts to work normally, which means that the part is broken. These parts include: a solar panel, battery, LED PCB, a control chip, and connecting wires.
In addition, replacing the new battery needs to be fully charged. The solar panels must be covered when doing lighting tests during the day.
