Hovmap 4x4 Solar Post Cap Lights Outdoor 8Pack, 3 Color Temperatures, 2 Level Brightness, IP65 Waterproof 16 LED Fence Deck Post Light for Wood/Vinyl Posts - Black

These are great budget post cap lights. They are pretty bright, and offer 3 different light color modes, each with a low or high option. Cold white, Warm yellow, and "Neutral" (I show them in the same order in my photos), the last being the brightest, as it just uses both the White and Warm LED's. Using the high light option won't last as long as using the low light option, and even the low light option is good and bright, so that's the mode I recommend. My first photo shows what the darkest brightness setting in Warm light looks like with the whole set lit up. They were super easy to assemble, set the color and brightness you want, then just set it on top of the base and twist, then attach it to your post. I recommend using the Warm color, as it is a more wildlife and pollinator friendly option, and contributes less to light pollution. But everyone will have their own preferences and needs. If you are using these for a deck or pathway, these are a great choice. You won't have the brightness of a spot or flood light, but it will be very helpful in dark areas.
