Choosing the Right Solar Post Cap Lights

GreenLighting turned on

If you’ve never bought solar lights before, the good news is that they aren’t that complicated to figure out. While they come in many different shapes and sizes, today we’re going to focus on a very specific subcategory, which is lights that you can mount on top of an existing pole. So, what are the characteristics that a buyer should pay attention to?

Size

Because you are buying a product that should be mounted on top of an existing object, it’s very important for these two to match in size. Basically, the light that you want to buy has to match the dimensions of the top edge of the post-it will be placed on. If the measurements are not correct, you won’t be able to install the post cap lights.

There are plenty of size variations for you to work with, but know that the most common ones are 3 x 3 to 6 x 6 inches, with 4 x 4 inches being the standard size for the majority of wooden posts found on patios and porches.

Weather resistance

Whenever you buy a product that has electrical components and is designed for outdoor use, it’s very important to pay attention to the waterproof factor. When it comes to choosing solar post cap lights, you will find that water, heat, or freeze resistance is even more important. Should you buy lights that aren’t waterproof, the first rain or snow will destroy them.

These products come with an IP rating, which is the standard measurement of protection in products that have a certain level of resistance to dust, liquids, and the likes. IP ratings usually consist of two numbers: the first one indicated to the protection rating that a device has against solids, while the second number refers to the degree protection against liquids.

Let’s look at more specific examples. When you’re buying solar post cap light (or solar lights in general), you want to pay attention to the second number mentioned in the IP rating:

  • If you see the number 8 as being the second digit of the two, you should know that is the highest grade for a liquid IP rating, which means that the product can safely be immersed in water (up to a level and a certain duration mentioned by the manufacturer).
  • If the second digit is 6, that means that the solar post cap light will remain safe from high-pressure water jets coming from either direction.
  • When the second digit of the IP rating is 4, it means that the lights will be safe from regular water sprays coming from either direction.

Compatibility

Aside from being compatible in size, post cap lights also need to be compatible with the posts that you want to install them on. For instance, some cap lights will only be compatible with a specific type of pole. You need to know that the poles in your yard are made out of one of three materials: PVC, wood, and vinyl.

The vast majority of solar post cap lights are designed for wooden post compatibility, as this is the most common material used to make posts in households. However, if your yard has posts made from vinyl or PVC, you need to make sure that the solar post cap lights that you’re looking to buy can be installed on these particular materials. These details are generally specified on the label or the product page of the solar lights you’re interested in buying.

Design

Of course, everyone wants a nice-looking yard, so every element has to fit the bigger picture. If your yard posts are round and painted in violet and you want to buy square-shaped lights that come in a brown case, it’s safe to say that your yard will look like something a three-year-old would paint if he had an unlimited number of colors at hand.

There are plenty of design tips that you can follow in order to give your yard a nice look. For example, if you have wooden posts, buying solar post cap lights in brown is a good idea. If you have black posts, you want to look for black fixtures. The idea is to match the color and shape of the lights with the posts as much as you can.

Runtime

Moonrays Post Cap Lamp

Runtime refers to how long a solar light will last when the battery is fully charged. What you want is a solar post cap light with as much runtime as possible, but be aware of the fact that you’ll have to place it in a spot where it can get the most sunlight exposure throughout the day. If you place your lights in a spot that’s sunny only for a limited number of hours during the day, the solar cells inside the panel won’t have enough time to charge to the fullest. Ergo, your lights may go out in the middle of the night because the battery is drained.

Most solar post cap lights that are available on the market have solar panels attached directly on top of the fixture, which can be problematic if the post you’re trying to mount them on doesn’t get sunlight exposure throughout the entire time the sun is up.

Runtime is usually a specification that most manufacturers mention beforehand, but always be skeptical about these specs. There are changes that lights advertised to run throughout the entire night will run out of battery in about 6-8 hours.

Top 5 Solar Post Cap Light Reviews

Now that we’ve run down the main characteristics that you should pay attention to when shopping for solar post cap lights, let’s move on to some actual examples. We’re about to show you the 5 best products in this category and (hopefully) see if you can find something in here for your yard.

Let’s talk about the solar post cap lanterns that customers are extremely fond of. These are available in sets of two lights, in both black and white. They are good for mounting on top of posts made from different materials, as long as they measure 4 x 4 or 6 x 6 inches. While the manufacturer claims they can be mounted on top of round posts, their square shape indicates that it’s best not to experiment.

The lights have an IP44 rating and, if you read the buyer’s guide we’ve written at the beginning of the article, you know what that means. The LEDs inside the fixtures promise us a lifespan of 100,000 hours, which is extremely generous considering the compact size of the lights.

The promised runtime on a full charge is 8 hours, and they have a light sensor that automatically turns the lights on when darkness is detected. Other features of interest include a matte texture for the outer casing, 3.2v 300mAh lithium-ion AA rechargeable battery, and two LEDs with 15 lumens in total.

Pros:

  • Available in black and white.
  • Compatible with multiple post materials.
  • LED life up to 100,000 hours.
  • Mounting equipment included.
  • 8 hours of runtime on a full charge.

Cons:

  • Casing feels cheap.

Pro Tip

Those of you that trust other people’s opinions and buying experience over every other marketing claim or professional review will surely want to see that these Davinci Lighting solar post cap lights have to offer.

Not only do these lights fit on wooden panels, but we’ve chosen them also due to their beautiful design. These fixtures are available in a white and black version, each with LEDs that have an 8-lumen output. These are designed exclusively for wooden posts, so don’t even try to install them on PVC or vinyl. Specifically, they are ideal for posts that measure 3.5 x 2.5 inches, and they come with a rail adapter.

You can opt between packs that contain two or four lights, depending on how many of them you need. Each of the lights measures 10.25 x 6.5 inches.

They have an integrated light sensor that turns the light on automatically when darkness is being detected. The solar panels are placed on the top side of the fixture so that it can get plenty of sunlight absorbed into the panel’s cells.

Pros:

  • Nice light pattern.
  • Lighting sensors.
  • Can be used as accent lights.
  • Easy to mount.
  • Cool-looking design.

Cons:

  • Questionable light lifespan.

Pro Tip

If you have some 3.5 x 3.5-inch wooden posts in your yard and would love a fancy set of solar post cap lights, these are definitely worthy of some attention.

Moonrays Post Cap Lamp

Moonrays Post Cap Lamp In Stained Glass Design (6x Brighter Solar Powered LED) in white background

Let’s move on to something a little more outstanding: solar cap lights with a different kind of design. The model we have chosen features stained glass that projects different colors throughout the scenery in your yard.

The LED inside the fixture is 7 lumen-worth of bright and promise to spread light evenly in all directions. While cool-looking, we have to admit that the stained glass does trap a little bit of light, so they may not be as bright as other solar post cap lights.

The lamps are made with bronze plastic and have a metal frame, plus four stained glass panels on each side of the light. They come with wooden screws, so they are compatible with wooden posts that measure 3.5 x 3.5 inches.

Pros:

  • Lighting sensor.
  • Beautiful design.
  • Wide-angle beam.
  • Included mounting hardware.
  • Easy to mount.

Cons:

  • Not as bright as advertised.

Pro Tip

If you want to try some solar post cap lights with a different design, we suggest that you opt for this model. It is made with stained glass that spread different colors as the LEDs inside illuminate the yard.

iGlow Solar LED Post Deck Cap

iGlow 8 Pack White Outdoor Garden 5 x 5 Solar LED Post Deck Cap Square Fence Light Landscape Lamp Lawn PVC Vinyl Wood in white background

  • Available colors: white, copper, black
  • Compatible with: 5 x 5-inch wooden posts

What we really like about these lights is that they are quite good compared to the low price per unit that you’re paying. What we didn’t like is that there isn’t enough information available about them before you buy them (like more details on what type of posts these are compatible with). Long story short: you only want to get these if you have posts that measure exactly 5 x 5 inches.

The design of the light fixtures is pretty basic, but we are particularly fond of the cooper version, which looks more elegant than the others. Each of the fixtures has one LED light installed inside, which promises to last up to 100,000 hours before it requires changing.

Pros:

  • Good value.
  • Bright for the price.
  • Can be used on wood, PVC, and vinyl posts.
  • Great for fence posts.
  • Three color options.

Cons:

  • Only work with 5 x 5-inch posts.

Pro Tip

In most cases, buying in bulk will save you money, which means that if you need more than just a couple of solar lights for your yard, you need to find conveniently priced packs, like this one. When you do the math, the iGlow set actually offers you a really good price per unit, making it an ideal purchase for people who are on a budget.

SunnyPark Post Fence Cap Lights

  • Compatible with: 4 x 4-inch posts

The SunnyPark lights are a sight for sore eyes. I’ll admit, the design was the very first thing that caught my attention. At first, it gave me a very snowflake high-school prom kind of vibe, but then I totally imagined a disco ball hanging from the ceiling in the roaring 70s.

Basically, these are globe-shaped solar lights that are made with plastic and glass and come in a very unique design, which makes them perfect for homeowners who want to be different from everyone else. The lights are compatible with posts that are 4 x 4 inches or smaller, although there is no mention of what the post material should be.

You can buy a pack of two or four lights, depending on how many of them you need. The LEDs inside are available in a cool white and warm white version, but there is also a multicolored version that shifts through the different colors to create eye-catching setups in your yard.

Pros:

  • The color-changing version is available.
  • Easy to install.
  • Screws and expansion plastic screws included.
  • Lighting sensor.
  • Different design.
  • Chic-looking.

Cons:

  • You can’t choose the color in the color-changing version.

Pro Tip

As you know, we’re all about promoting products that we think are good even if people didn’t really have a chance to test them so far. Today’s staff choice is the solar light made by SunnyPark. If you want a cool-looking solar post cap light that comes with really neat crystal glass (or if you basically want to own solar lights that are different from everyone else’s), this is the one to try.

Bottom Line

Solar post cap lights are a wonderful way to turn otherwise dull-looking posts from your yard into poles that can sustain a mean of illuminating your garden. These are an energy-saving method of converting the sun’s energy into light that can be used to showcase the beauty of your outdoor arrangements in the dark, but also to help you find your way through the garden once the sun goes down. Most of these listed are suitable for home use, but if you’re looking for something more heavy-duty for outdoor or commercial use, like lights that are ideal for a stadium or ice rink, then we’ve got some recommendations for you!
