Deck Post Lights can significantly amp up the atmosphere on your deck, and also provide gentle illumination without wiring and headaches. After looking at several 4x4 post light caps, we’ve found that the best solar deck post lights are the Davinci Solar Post Lights - Outdoor Post Cap Light. The Davinci models remain bright for a long time and emit a light that is bright enough to improve vision but not so much that they ruin the landscape. Another great feature is their unique “fuzzy fit” design. This means they can fit on all 4x4 in. posts without requiring more specifications or measurements. They are also affordable and won’t break the bank.

Post Cap Solar Light Buyer’s Tips
Picking the right set of solar deck post lights can be a bit of a difficult process, due to several factors. Materials, sizing, post types, and packages all collide to make picking the right set a head-scratcher. In this section, we’ll break down some of the important apsects to keep in mind while deciding which are the right lights for you.
Number of Lights Needed
First off, count up the number of lights you need to cover your needs. Typically you’ll want one light per post, simple as that! Count all the posts on your deck and/or stairs. Now you’ll need to keep that number in mind, as most all solar post cap lights come in packages of 6, 8, or more. If you have 9 posts that need lights, you may be stuck purchasing a whole bunch more than you need, which isn’t ideal. However, it means you’ll have some backups if one of your lights fails, breaks, or otherwise ceases to work. Lights that come in packs of 2 mean that you’ll only at most buy 1 more than you need, but generally there is savings when buying in bulk.
Post Sizes
While most of the post light manufacturers say their lights will fit “standard” wood posts, or “standard” vinyl posts, this is always a bit of a fudge space. The dimensions can become confusing, as wooden 4“ x 4“ posts aren’t actually 4“ square, while vinyl posts are. Let’s dig into the details.
Wooden Posts
The vast majority of wooden posts are 4“ x 4“ nominal posts. This means they’re 3 1/2“ x 3 1/2“ in size. A post cap larger than 3.5“ square will fit over most any wooden post. That said, some wooden posts are 6“ x 6“, so be sure to measure your posts. The good news about wooden posts is that it’s generally pretty easy to shave down your posts a bit if you need a little bit of wiggle room to get your caps on. It’s highly unlikely that little adjustments will be noticed on wood posts.
Vinyl and PVC posts
Vinyl and PVC post sleeves are generally designed to go over wooden 4“ x 4“ posts (actually 3.5“ square). These posts are typically either 4“ x 4“ actual dimensions, or 5“ x 5“ actual dimensions. Be sure you check the actual dimensions for your post sleeves. As most vinyl and PVC posts are sitting on top of a wooden post, you could consider trimming the vinyl post down below the cap and mounting the cap to the wood inside the post. This will not be noticeable if done correctly. Just be sure you check your dimensions carefully.
Post Materials
Depending on the materials you’ve chosen, some post caps are designed to go over wood posts (they’re suited for 3.5“ posts) while others are designed for 4“ posts. The bottom line is that wood posts are almost always smaller than vinyl or PVC posts, and if a cap is stated to work well for wood, it won’t likely work well for vinyl without some fussing with the post.
Finishes
There are a wide variety of materials and finishes on the market for solar post caps. The vast majority of vinyl and PVC fence posts are white, though there are obviously colors available. Generally, white caps will look best in these circumstances, but you can get creative. Wooden posts can be painted or stained in a ton of different colors and finishes. In these cases, often bronze, brass, black, and other finishes can look great with these posts.
Sun Exposure
The more sun your post caps are exposed to, the more they will glow at dusk. Naturally, many fences and decks are in a wide variety of exposures to sunlight, and consequently, you may find the post lamps in the part of your fence obscured by lots of shade to be noticibly dimmer than areas with lots of sun. There’s not much you can do about this other than removing the shade areas.
Illumination
Different posts have different illumination values and lengths of illumination per charge. Most of these lights produce ambient light. The ambient light will offer a nice attractive glow, but will not illuminate enough for task lighting, or even for simply hanging out in the yard. For this reason, you’ll probably want to combine your post lighting with other deck surface mount lighting, solar yard lighting, and general outdoor string lights to help make your gardens look amazing.
4x4 Deck Post Light Reviews
A solar deck post light is a specific type of light designed to sit on top of deck or fence posts and provide lighting during the night. The products touched upon in this review are lights specifically for posts which measure 4x4 in. These come in a few different shapes and sizes, and can work on a variety of post materials including wood, wood-like material, plastic, and others. Since these lights can come in all shapes and sizes, it can be difficult to find ones that work well, fit well, and remain bright for a long time.
