Customer Questions & Answers

The metal post I want to put the light on is 4 3/8 in. diameter round. What is the best way to affix the light to the post?

Asked by: Richard
Thank you for your interest in DeckoRail. Unfortunately, the 4 in. x 4 in. Antique Black Solar Post Cap will not fit your 4-3/8 in. round post. The actual interior measurement of the solar post cap is 3 5/8 in. x 3 5/8 in.

Can I purchase replacement parts? Do they have rechargeable batteries that stop working? Can the tiny LED lights inside be replaced?

Asked by: ToJo
Thank you for your inquiry. Replacement parts are not available for the 4x4 Antique Black Solar Post Cap. The LED bulbs are part of the post cap and are not designed to be replaced. The LED bulbs have an average life of 10 years, with a normal use of 6-8 hours per day. The batteries included with the post cap will eventually stop working, depending on the amount of recharge and use it gets each day. You can expect them to last at least one year and they can be replaced by any AA rechargeable battery.

4 in. x 4 in. Antique Black Composite Solar Post Cap is rated 2.7 out of 5 by 11.

Rated 1 out of 5 by from Solar cap lights are not worth the money. The solar cap lights last only one summer season, that is why the warranty is only 90 days. Expensive ni-cad batteries are necessary, then when you buy replacements and install, the top unit fails to light. Bugs, nats and spiders love them as habitats. Do your research before you purchase!

Rated 4 out of 5 by from Glue I liked the look of these. I bought 4 and took one out of the package and placed it near a window. It charged and had good illumination. However when I reviewed the installation there is no way to screw these to the post cap. They must be glued. That means if they fail or are damaged the only way to replace them is to cut the top of the post off. For that reason I returned them. They were a little more expensive than others I looked at but I wanted the black which is not as readily available as brushed copper or white. The quality seemed a bit better than others I looked at. The only reason I returned them was the use of glue for installation. Also there isn't enough of a lip to drill holes for screws without risking cracking the housing.The lights I replaced them with are ok, but not as well made and don't provide as much illumination as these did. So if you don't mind the glue I'ld recommend them.

Rated 4 out of 5 by from West Only Make sure you install these on the western portion of your home. Mine are on the eastern side of my house with no trees or anything blocking them and they barely glow (as in you can't see them from 10 feet away). When I did my test before installing them I put them out on my back porch for the 2nd half of the day and they glowed in my kitchen all that night and part of the next day. They look very pretty and are sturdy, and I was very happy to be able to install them with a screw (after drilling my own holes). They're ok, but not worth the $25 each.

Rated 3 out of 5 by from just okay make sure you understand that this is just a glow. not a light. if that's all you want then these are good and easy to attach. they seem to stand up well to the weather as well

Rated 1 out of 5 by from poor lighting Poor lighting, the light stayed lite was for maybe 2 hours.Very poor lighting you could barely tell it was on. I returned the item to homedepot in Silver Spring, Maryland

Rated 4 out of 5 by from Post Light I am very pleased with the quality & look of the post light. The only thing I would like to see is some small screws to mount on the post instead of the glueing method the instructions said. I used double faced tape and it seems to be holding the light on the post securely.

Rated 1 out of 5 by from I put these on our retaining wall, as a warning to friends and family, it's a 4 - 5 foot drop!. They light up just enough to do that. I was disappointed with the low light. They do look good, in daylight, as you can't see them so well at night. They are really pricey - if I still had the box, I would return them.
