Choosing a Solar Post Cap Light – Things to Consider

Just like with every other appliance, there are various types of solar posts with different features peculiarities. If you hope to make a good solar post cap light choice that will serve your purpose, there are some features and factors to consider.


Any light fixture that is to be installed outdoors should be adequately protected against the negative effects of weather elements. In particular, waterproofing is a very critical factor in outdoor lights. Nonetheless, you should consider also consider heat and freeze resistance. Almost all solar cap lights are touted by the manufacturers as weatherproof, but in reality, there are varying weather-resistance levels.

Thankfully, there is an IP rating system that is the standard for how resistant to weather elements a light is. A typical IP rating has two numbers, the first being the protection rating against solids and the second, the protection rating against liquids.

For the first number, a rating of 6 is the optimal rating for protection against dust. It implies that the light is dust-tight and protected from the damaging effects of dust. A rating of 5 means the light is protected, to an extent, against dust.

The second number is what you want to pay more attention to. The number 8 is the highest waterproof rating you can get; it connotes that the light will be adequately protected if immersed in water. A rating of 6 means protection against water from high-pressure jets, while an IP rating of 4 means the light is only protected against water sprays.


This implies the coverage of the light emitted. The brightness of light as it appears to the human eye is rated in lumens. You certainly do not want to install solar light that will not offer sufficient illumination, even if that is not your primary purpose for installing the lights. There are lights that produce as low as 100 lumens, while some produce as bright as 300 lumens. The optimal brightness range for solar post cap lights in residential areas is 150 – 200 lumens.


In general, solar lights are powered by rechargeable batteries store up energy from the sun. The charge duration and runtime are by the capacity of the battery. These are details you should consider before you make any purchase. The higher the battery capacity is, the longer run time it has when fully charged. However, this implies a longer charging duration.

It is not just about having a high battery capacity. You should consider if your climate supports the ideal charging duration, which is 6-8 hours in direct sunlight.


There are a couple of factors that influence the durability of a solar light. The material is one of the key factors; that is in addition to factors like waterproofing. Most of the solar post cap lights that dominate the market are made from plastic materials, even though they are not the most durable materials.

If durability is really important to you, you should opt for lights with a steel or aluminum construction, as they are more durable than plastic lights. Not to take anything away from plastic solar post cap lights, they can be reasonably durable as well.


Installing solar post cap lights is a straightforward process. Choose lights that come with the materials needed for installation, as you may find it hard to get these materials separately. Even if you are not so handy, you should still be able to handle the installation of your solar post cap lights. Choose models that are straightforward to install. However, if you are not confident in your ability to carry out the installation, you should get a professional.


We sincerely hope that you find one of these solar post cap lights the perfect option for your immediate outdoor environment. There are unlimited options on the market, but these are some of the best in terms of aesthetics, functionality, and affordability. Typically, these lights are versatile and can be used for a variety of outdoor purposes. If you have any regard or care for the environment, these clean and environmentally friendly lights should replace your typical electric post lights.
