Best For Concrete Pillars: Davinci Lighting Edison Solar Outdoor Post Cap Lights
- Ideal for concrete pillars
- Classic and retro looking - the unique Edison-style design
- The most affordable
- Installation accessories are flimsy
- The painting not lasts long
Although the Davinci Lighting Edison comes with multiple bases for plastic and wooden posts, it's still possible to mount the light onto concrete, as long as you have the correct hardware.
While mounting is an option, a silicone type or glue is also a great alternative if you don't prefer to leave any holes on your pillars.
This solar-powered post cap light gives off 30 lumens of warm white light that can last up to eight hours if fully charged during the day.
It brings a great retro touch to your outdoor space, thanks to the unique Edison-style design.
The housing is made of high-end die-casting aluminum frame and glass, with IP44 weatherproof rated construction, making it sturdy enough to bear light rains and high-humidity conditions.

How To Choose The Brightest 4x4 Solar Post Cap Light?
Posts’ Materials That The Solar Lights Are Compatible With
Each post cap light is built to be compatible with pillars of certain materials. Therefore, it’s important to consider this factor when you go shopping for the best brightest 4x4 solar post cap lights.
Luckily, most manufacturers provide this piece of information in their product’s listing.
Pillars of deck and patio are regularly made of concrete, vinyl, or wooden. Most solar post cap lights are compatible with wooden and vinyl, only a few can pair with concrete.
Battery Charging And Working Time
The term “charging time” lets you know how long it takes for a solar post light to fully charge.
Runtime means how long it will last at night.
The ideal charging time is 6-8 hours, depending on the type of battery. Typically, the runtime is 6-10 hours once fully charged, however, some models equipped with premium batteries can last up to 12 hours.
Note: Harsh weather conditions decrease the solar panel’s effectiveness. So, it’s worth considering if the solar post cap lights you’re about to choose can work well in the weather type of your area.
For example, if your area is frequently cloudy, look for a product that can charge well in such type of weather.
Style
Although the style and design of a solar post cap light is not the most important factor for functionality, there’s no denying that it greatly influences how your patio, deck, or back yard looks.
Below are the most common styles of solar post cap lights:
- Flame effects
- Modern solar post cap lights
- Spherical solar post cap lights
- Honeycomb covers
- Faux weathered finishes
- Lantern-style lights
Durability
As solar post cap lights are installed outdoors, you should consider how well they resist to inclement weather conditions, such as snow, sleet, storm, and rain.
Most solar post cap lights feature an Ingress Protection, or IP, certification.
For your information, the IP rating system has two digits. The first one indicates the resistance of the device to solid objects, with the scale ranging from 0-6 (the larger the number, the more resistance to solid objects like dust and debris).
The second digit shows the resistance of the device to water, ranging from 0-9.
For solar post cap lights, we recommend choosing products with water-resistance rating from 5-7.
