Question: the wood post is a really 4x4 no 3.5 x 3.5, will this cap be good for this? it said dimensions are 5.9 x 5.9 x 4x4
Document: Beware--these caps do not fit vinyl posts! I gave it 3 stars because the product is nice--well made and worked well when tested, but the description is misleading. It would probably fit a 4 X 4 wooden post, but they aren't really 4 X 4, are they? My vinyl post measured a true 4 X 4, and the cap didn't come close to fitting. It had to be returned.
second one I've bought, first lasted a couple of years but water got into the chipset. for the price, and for those who want a white cap, this is a good product
so far so good customer loves themtime will tellbefore we know if they're 5 stars or not ask me in a year
Works as intended, very nice n bright! Works on 4 x 4 wood posts only. Very durable, would recommend. Went to the Fence supply company and they had the very same lights for $27 each....
Fits perfectly and easily (couldn't be easier to attach) on a 4 x 4 post. My posts are white and this looks like part of the post. Is attractive, but not especially bright. We do have some shade so that may make a difference in its brightness. This suits my purpose perfectly.
The post caps help evening visibility on my side stairs (to driveway) and depending on the amount of sun they receive during the day, they can last up to 9 - 10 hours. When the days get less sunlight, it may be as little as 4 hours.We have received many compliments from guests.
Cheap plastic, made in China stuff. Had to throw the battery in each one with a new one right from the beginning because they are cheap and don't hold a very good charge and the lights stay really dim. With a new battery they are brighter, but they are not for lighting an are, just good for an accent.
It's plastic so don't expect an Artisan post cap here, but guess what, it protects the ends of the posts and looks reasonable. The price was right as they didn't cost much and they do stay on through the night. Not the brightest but the LED chosen was probably matched to using one battery and the number of hours it would stay lit. For the price I'm satisfied.
This light is very good for the price. It does not illuminate an area very well, but does throw off a lot of horizontal light. I think if they had designed it differently, it would illuminate the area better. If you are looking to light up a gate or fence post, this will work very well.
These lights are gorgeous! They are on as soon as the sun goes down and stay on for at least 9 hrs. Love them!
