Solar post cap lights come with different lumen counts that range between 100 and 300.

  • 100 lumen is enough if you want to use the lights in your garden.
  • On the other hand, you should use 150 to 200 lumen-lights if you want to light up your walkway or driveway.

How are solar post caps measured?

The best way to measure solar post caps is to go from one of the inner walls to its parallel side’s inner wall.

According to experts, this measurement system provides maximum accuracy as the external solar post cap will sit directly on top of the post.

This means you need to measure the post in such a way that it fits tightly enough to prevent water from penetrating the post’s surface.

Sometimes, the external post cap may look bigger than its actual measurements. This is because of the tapered-down design of the entire light set.

In such cases, you should measure from the post cap’s walls inner edge to its opposite side’s inner edge to match with the corresponding post size.

What solar post cap size do I need?

Finding the right solar post cap size may be a time-consuming process. This is because you need to select post cap lights of different options and sizes.

You should first decide where you want to install the solar post cap light.

  • For example, if you want to install multiple lights in your driveway, then small-sized lights are appropriate.
  • On the other hand, if you want to light up your deck, you can pick bigger lights.

Measure the area where you want to install the lights before buying them. It helps to pick the best size because you know the number of lights that will fit in that space.

How to use solar post cap lights?

Step 1: You need to measure your vinyl, PVC, or wooden post before installing the solar post cap lights. Make sure you buy the lights according to the measurement of the posts.

Step 2: Once you bring home the lights, remove the insulating sheets attached under them.

Step 3: Next, drill two holes on the post where you want to mount the light. Align the solar post cap light with the drilled holes and place them gently.

Step 4: Use the screws you get when you buy the lights. Tighten the screws and check whether the solar post cap is wobbling or not.

Step 5: Try switching on the light manually. The light should illuminate if its battery has enough power.


1. Do solar post caps work in shady areas?

Yes, they do.

The operation of your solar post cap depends on the quality of the solar panels. High-quality solar panels derive more energy from the sun even if you keep them in relatively shady areas.

2. Which light should I buy: warm white light or cool white light?

Cool white lights light up your deck or driveway. But if you want a soothing ambiance, go for warm white lights.
