The Best Solar Lights for Fence Posts

One of the biggest attributes to installing fence post caps is their visual appeal. Fence post lights can give your fence a distinguished look and they come in a wide variety of styles and colors. Solar LED Caps can add class and flair to any fence. They look great at night and are both functional as well as being ornamental.

Below we have listed some of the most popular solar lighting systems currently available on the market so take a look, and see if any one of these models catch your interest. We have chosen these models based on specifications, pricing, customer reviews, and overall design as well as aesthetic value/looks.

iGlow Black Outdoor Garden Solar LED Post Deck Cap

iGlow 8 Pack Black Outdoor Garden 6 x 6 Solar SMD LED Post Deck Cap Square Fence Light...
View on Amazon

Without a single doubt, this 8 LED solar light pack from iGlow is the best all round fence lighting product money can buy right now. It is because of several reasons, the most important of which is the fact that it is fully equipped with all of the latest convenience features such as ambient light level detection (for automatically switching on when it begins to get dark), as well as an advanced solar panel for faster charging. Installation is extremely easy, all you have to do is screw each of the 8 individual lamps onto your fence posts, no wiring or other shenanigans required.

All of the components have been packed into a clean looking and aesthetically pleasing body that will look amazing as it sits on your fence posts, while the exterior look reminds viewers of a lamp from the 19th century, it is actually one of the most efficient and reliable pieces of solar lighting equipment currently available on the consumer market. Dimensions are 7.5” (L) x 7.5” (W) x 4.8” (H). You will be able to set the lamp on any 6” x 6” fence post, and even newer 4” x 4” posts with some slight tinkering.

The base measures 6” x 6”, and each of the 8 lamps are equipped with SMD LED arrays and are rated at 20 lumens. The pre-installed rechargeable AA 3.2V Li-Ion batteries will last up to 3 years before they need replacement, and rated lifespan of each lamp is up to 100,000 hours. So even if you use them for 12 hours each day, they should still last more than 22 years. And yes, the whole set is designed to be both rain as well as snow resistant thanks to the incredibly tough PVC plastic shell and insulating coating that protects the interior components from water, wind, and dust.

iGlow Copper Solar LED Post Fence Light

iGlow 8 Pack Copper Outdoor Garden 4 x 4 Solar LED Post Deck Cap Square Fence Light Landscape...

Just like the previous model from iGlow which was our top pick, this one too comes with 8 solar lamps included in the package. However, the set costs about 40% less in comparison to the Black Outdoor Garden set, which is rather surprising at first considering that both solar fence lighting sets are made by the exact same company. However, upon taking a closer look it becomes clear as to why it is so – the 8 Pack Copper Outdoor Garden set comes with lights that are slightly less powerful than the ones found the Black Outdoor Garden set (those were rated at 20 lumens). Also, these lights are slightly smaller with dimensions of 5.75” (L) x 5.75” (W) x 4.5” (H), and the base measures 4” x 4” instead of 6” x 6” like on the previous model.

This means that you should be able to comfortably mount these onto a standard 4” x 4” fence post without needing any modification work whatsoever. The shell is made from a mixture of wood and plastic, and looks pretty sleek with its bold edges and clearly defined faces. The package comes with all the fittings that you need in order to mount the lamps onto your fence, and they are built to be used with wooden or composite posts only.

Just like in the Black Outdoor Garden set, SMD LED’s have been used for even lighting and efficiency, while the rated maximum lifespan is still a massive 100,000 hours. The pre-installed AA batteries will last up to 2 years depending on your usage, which means that you have plenty of time to work with before the lamps need a battery replacement. The lights are not the brightest, however they are perfectly fine for illuminating a small to medium sized driveway or porch/garden. They will light up automatically as the natural light decreases, and will switch off during daytime as soon as ambient light approaches the threshold level. The shell is weatherproof to protect the internal components.

Paradise Solar Cast LED Post Cap Light

Sterno Home GL23877BK Post Cap Light, 1-Pack, Black
View on Amazon

This solar fence post light from Paradise is truly unique in terms of design and layout, since unlike most other solar fence lights it does not have a flat base and a cylindrical structure with the solar panel on the top and an omni-directional light right beneath the panel. This particular light consists of a vertically aligned front facing lamp with a horizontally aligned solar cell and panel combo unit bolted to the top section of the lamp.

This means that you will not get unidirectional light, and the lamp will be mounted with its back against the post so the area to the rear of the fence will be in shadow. However, the positive side to this design is that all the light is spread out to the front end, much like the headlights on a vehicle, which results in much better spot lighting than a conventional solar fence post light. On top of that, the solar panel used in this light is a crystalline panel instead of the amorphous ones that you’ll find on regular solar lights.

Crystalline solar panels charge the battery faster, and they last longer. The ambient light sensor allows this fence lamp to automatically turn on at dusk, and shut down at dawn. The weather-resistant frosted plastic lens and durable PVC plastic body protect the lamp from rain, snow, dust, etc. In the package, you get one fence post light, a single AA Ni-CD rechargeable battery, fittings for mounting, a user manual/installation guide, and a one year warranty.

Paradise Bronze Aluminum LED Post Cap Light

Paradise by Sterno Home Solar Cast Aluminum LED Post Cap Light for 4x4 Wood Posts, Bronze...
View on Amazon

Crystalline solar panel, super long-lasting Nickel Magnesium Hydride rechargeable battery, weatherproof hammered glass lens, and bronze finished cast aluminium body – that’s what you get when you purchase a Paradise GL28998BZ Solar LED fence light. Quality, and performance, which is not cheap by the way – it costs significantly more on a per-light basis in comparison to what you find with a full set of 6 or 8 solar fence lights.

The reason behind this high cost is obviously the premium hammered glass and cast aluminum body, that make this lamp virtually impervious to shock and wear. It is extremely powerful in terms of light output too, and is just as bright or even slightly brighter than our top pick, the iGlow Black Outdoor Garden lamp set. However, the nickel magnesium hydride battery is inferior in comparison to the Li-Ion battery found in the iGlow model, meaning that recharging will take longer and the overall lifespan will be slightly less (battery lifespan, not lamp lifespan). The overall build quality and looks are however the best of any solar fence light we have ever seen, and installation is extremely easy – barely takes 3-4 minutes to get one of these installed on your fence.

Choosing the Best Solar Lights for Fence Posts

Solar lighting is rapidly growing popular due to various reasons, the most prominent of which are the efficiency gains and eco friendliness of this form of lighting, compared to conventional lighting technologies. Solar lights are available in many forms and designs, but the basic principle remains the same in all of them – they all consist of 3 main parts which are the solar panel, a rechargeable battery, and the light itself (usually a LED array). An LED array is preferred instead of an incandescent light or CFL/ halogen lamp because LED’s are the most efficient and cost effective form of lighting we currently have.

They require extremely small amounts of power to operate and can be powered with very low voltage. Solar light cells don’t output a lot of power unless you put together a giant array of them like in solar power farms, and the solar panels on your typical solar fence post light are extremely compact so that the fence post can accommodate the light. These days, most fence posts measure 4” x 4”, so most solar fence post lights are designed with these dimensions in mind. However, you will also find that the exact same lights can comfortably be fitted onto older 6” x 6” fence posts as well.

Choosing the right solar light for your fence post is not a very difficult task at all, provided you know what to look for. There are some basic concepts that you must already be familiar with if you ever shopped for a light before. The first metric is obviously the luminescence of the light, which is measured in lumens. This number will tell you how bright the light is, and how big of an area it can illuminate. For the average home, an array of a few 20 lumen lights should be all that you need. Depending on how many mounting locations you have and the amount of area that you need to cover, you might wish to get more lights or just get more powerful individual lights to compensate for a smaller number of lights.

Accent lighting can be done in many ways, and it all depends on the area that you are trying to cover. Driveways and patios require a linear alignment of similar lights to provide a feeling of continuity, while fence post lighting can be tweaked and experimented with by adding multiple types and sizes of lights to cover the same area such as a lawn or orchard. You can choose to focus the lights around an important part of your home, such as the gateway, or the nameplate. You can also set up lights of different colors around the fence, in order to create a much more vibrant lighting effect.

Finally, before purchasing a solar lighting kit for your fence posts, you need to confirm that the individual lights are all equipped with weatherproof shields and ambient light sensors. The protective shielding will ensure that your lights are able to withstand the forces of nature, such as snowfall or rain, while the ambient light sensor will allow your solar lighting system to automatically switch on at dusk so you don’t need to turn it on manually. This feature is great to have if nobody is at home (you’ve gone out on a trip/vacation), since it will give the impression that people are still in the house. Besides, it is simply convenient and relieves you of the chore of having to manually turn on the fence lights every day.
