What are solar flood lights?
If you look at the base definition of a floodlight, you will realize it is a large, powerful light that most people use to illuminate the exterior of their house. This can be in your backyard, driveway, porch, and more. The solar flood lights are just a variation of the same. The main disparity is that instead of being connected to the house electrical grid, the lights are independent and get their energy from harnessing the sun’s rays.
Benefits of solar floodlights
Mentioned above is the fact that floodlights aren’t connected to your household power grid. As such, they help save on utility costs since they derive their power from the sun.
Also, most people don’t want to add to environmental degradation. Using solar flood lights reduces the need to use non-renewable sources of energy that provide our households with power. The result is that you pitch in a little to environmental conservation efforts.
Another benefit comes in the form of safety. This, again, is attributed to the lack of a link between the device and the electrical grid. As such, if it malfunctions, the damage is limited to a single machine. In contrast, where the product is connected to other wires in the house, it may damage your other appliances and has even been known to cause fires.
Features to consider when choosing solar-powered floodlights
We mentioned the features that help you decide which solar-powered floodlights would be ideal for your needs at the beginning of this write-up. In this section, we delve more in-depth so you can have a better grasp of how you will choose the solar-powered device you end up purchasing.
Type of the solar panel
If you have researched solar panels in general, you will realize that there are three main types to choose from. These are the amorphous, polycrystalline, and monocrystalline options.
Once you are aware of this, you should then set out to know the benefits and limitations of each.
Monocrystalline solar panels are, at the moment, quite popular. They are characterized by a durable body, take up relatively small spaces, and, in comparison to the rest, produce more electricity. At the same time, you have to account for the fact that the performance may fluctuate a lot in response to different weather patterns.
In comparison, polycrystalline solar panels tend to be less expensive. They as well feature a more straightforward design when compared to their monocrystalline counterparts. Again, their design comes with two major flaws, including being bulky and having relatively low heat tolerance.
Amorphous solar panels are unique as well. Despite taking up a lot of space, they don’t produce a lot of electricity. However, they can be appealing to look at and have the added advantage of being the most affordable.
Out of the three, you will likely have to pick one since solar flood lights are often limited to having a single solar panel.
Number of LEDs
Checking the number of LEDs available in the product is also something potential users should do. This number is as well likely to affect the intensity of the light output. The LEDMO Upgraded 200W LED Solar Flood Light is an excellent example of this.
Battery type and capacity
Solar flood lights often include rechargeable batteries in their construction. After all, this is where the energy collected from the sun is stored. It is also where the lights derive energy from to light up the area at night.
The main rechargeable battery types you may encounter as you look deeper into solar flood lights are lithium-ion, NiMH, NiCad, and Lead Acid options.
As compared to other batteries, lithium-ion batteries have low self-discharge, high energy density, and almost no memory effect. For those who don’t know about memory effect, it comes by when batteries are not fully charged, and the product reduces its future capacity as a result.
High drain solar flood lights would probably work best with Nickel-Metal Hydride (NiMH) Batteries. Capacity-wise it can hold up to three times the energy stored in a NiCad battery. Additionally, the energy density is almost on par with lithium-ion batteries.
Nickel-Cadmium Batteries (NiCad) are quite adept at holding a charge when no one is using them. However, they may be the most susceptible to the memory effect. Nevertheless, they offer high discharge rates for their full capacity and perform well in low temperatures and can last a long time.
Lead-acid batteries can be considered one of the low-cost options. However, they are capable of holding enough charge for use in heavy-duty applications. One significant benefit is that they are ideal for high-current uses, such as starting cars. Nevertheless, they are often quite large and bulky and hence cannot be moved easily.
Run time and charging time
Ideally, you want solar led flood lights that can provide illumination when needed. In some cases, that can be all night, and devices that have 10+ hours run-time are ideal. From the list above, the LEDMO Upgraded 200W LED Solar Flood Light with its 20-hour run-time comes to mind.
Others can spread their short run-times over short bursts of use. An example is where solar motion flood lights like the GLORIOUS-LITE Solar Security Light have a maximum run-time of about 50 minutes. However, since it can only stay on for a maximum of two minutes after motion is detected, the run time will still be enough.
If you want to navigate run time in your purchase, be aware of your needs beforehand. Also, the charging time is essential as well. Short charge times means that the battery will always be full as you go to bed at night. This, of course, guarantees that the light won’t shut down in the middle of the night when the battery runs out.
You will note from the list above that brightness varies from device to device. Some good performers are like the CNSUNWAY LIGHTING 100W Led Solar Flood Light that have over 5000 lumens in brightness.
Often the solar security floodlights with high illumination levels also have a way of reducing the light intensity. This is why you should look for a light with a higher maximum brightness level.
It also makes sense to purchase a tool that is tailor-made for the size of your property. If, for example, you want to light up your back yard for security purposes, there is no point in leaving blind spots. As such, if your area is 30 square meters, purchase solar security floodlights that adequately cover that area.
If the space is large, you can either purchase a matching device or a few of them to cover any dark spots left behind.
Additionally, the product you buy should be well worth your money in terms of how long it lasts. This is why you look into attributes such as construction and warranty. Also, since this is an outdoor device looking at the weatherproof rating is essential as well.
Modes available on each device can also tell you a lot about its versatility. The most common modes include normal, bright, dim, motion sensing, light sensing, and more. Each of these modes will, of course, be ideal for different scenarios. As such, the more the modes available with a purchase, the better.
Power of solar panel
If a solar panel produces more power, it will likely fill up the battery a lot quicker. This will lead to shorter charge times. Also, a higher power solar panel will probably be coupled with a higher-capacity battery, so the energy produced has somewhere to go. As such, a high power solar panel could be immensely beneficial to the user.
A few extra features may be expected with some of the solar flood lights you check out. If you feel they are worth the additional cost they often come with, you shouldn’t shy away from the purchase.
An example of such is motion-sensing capabilities such as those shown by the GLORIOUS-LITE Solar Security Light.
