Question: so these will fit on a 4X4 Deck Post
Document: As it says they are plastic. Loved them right out of the box. Fit perfectly on my 4 x 4 post, easy to install and nice copper color. It has been about a month now and they are no longer copper looking. The bottom copper color is a little darker than the top but not much. They look more like a yellowing silver from sun fade and have water on the inside where the bulb is. Very disappointed in the quality.
I had to make some modifications to fit my post snugly. I wanted it to be placed on top and around the post head. From the picture you can see that it wants to be just on top. It does come in multiple pieces, so I trimmed the bottom part of its  wings and it fit relatively snug. I then added some caulking, so ants would not get inside. Overall - for the price I'm happy with the purchase.
Described as containing 5 LEDs, but there is only one. I never expect solar lights to be very bright, but the opaque side panels further dim the light and give a yellow glow. They do fit nicely on a 4x4 post, so I thought I would keep them initially. Then it rained and the lights filled with water. If they are attached to the post with screws, as they are designed to be, you cannot pour out the water. These were such a disappointment and were returned.
I bought 6 packs of the product to fit 10 posts on my patio deck (plus 2 spares) and was very disappointed when I received the solar lights. See list below for cons:1). One of the boxes was missing the fastener screws.2). The supplied fastener screws are too thick to fit the small pre-drilled installation holes on each side --&#62; I had to enlarge each hole  with a drill bit so they fit snugly.
There are some small drain holes inside to channel it off, but is not thought out well for applications on posts since the water has nowhere to go when unit is butted up against the post.6). You can see the solar panel cells connecting wires on top, which is not the case with better quality solar light designs where they are hidden or at the bottom.
If these go out during next winter, we will keep them and just replace the batteries. The design of these lights is outstanding! They have a nice, square post shape including an entire square of light showing on all 4 sides, rather than having a small panel showing 1 tiny bulb inside, which is what most solar path lights look like. These solar lights even gave enough light to help during recent power outage!
Mounted the post lamps and they worked great and looked really good. Then it rained and the problems began. They filled up with water in no time and then of course they stopped working. I took them apart to dry them out and removed corrosion from battery contacts. When I reassebled them I made sure that the drain holes where cleared and sealed the light with silocone at the assemble points. A few days later it rained again and they got water in them and stopped working.
WE MOUNT THE TOP PART ON A 4X4 THAT LOOKS LIKE THE TOP OF THE POST THROUGH THE RAILING. WE DON'T USE THE BOTTOM PART BECAUSE THAT MAKES IT LOOK CHEAP. ALL IN ALL I'VE LOOKED AT SOLAR DECK LIGHTS EVERYWHERE AND SETTLED ON THESE.
