Custom Fit for TimberTech Radiance Rail Express

This post cap is precision engineered to integrate with the TimberTech Radiance Rail Express composite post series, delivering a clean, flush look that complements the high end finish of your railing system. The same tailored fit accommodates 4.25 in. x 4.25 in. aluminum and steel posts with an identical actual outer diameter, so you can standardize on one fixture across mixed material installations.

Patented Magnet Brightness Control

Integrated patented magnet technology lets you cycle through 7 distinct brightness levels or deactivate the unit with the included magnet. You can tune the output to meet specific seasonal performance requirements or extend runtime during periods of reduced sunlight, keeping the light functional and effective throughout the year without any wiring or physical switches.

Built for Long Term Outdoor Exposure

The housing is fabricated from ASA UV resistant composite material to prevent yellowing and structural degradation from prolonged sun exposure. Internal electronics are fully protected by an IP68 rating for fresh water and salt water coastal areas, and the high power solar panel is reinforced with tempered glass lamination for superior scratch resistance and energy collection efficiency compared to standard plastic alternatives.

User Replaceable LiFePO4 Battery Included

Each Solar Post Cap Light is powered by a user replaceable advanced lithium iron phosphate (LiFePO4) battery, included with the unit. LiFePO4 chemistry delivers a stable and long lasting power source that supports the high output white LED array, and replacement cells are available through the banner link at the top of this page for long term serviceability.

Great interactive toy for pets
Color: Red
Very amusing interactive toy for pets! Our toddler got a kick out of this too :) Keeps our dog entertained and engaged. The battery life was decent and easy to recharge. It has 3 different settings for the movement depending what your pet likes. We had it go under furniture in hard to reach spots, but it is pretty good at moving itself out which is a plus. Great toy if your pet likes to chase.

One of the Best Toy I’ve Gotten My Dog-Now Buying Our 5th Because He’s Obsessed
Color: Blue
My small mixed breed dog is high intelligence, energy and emotion. Since he was a 2lb puppy, he’s gotten bored with regular dog toys. I came across these when searching for a ball that lights up, not knowing it would be one of the best things I could’ve purchased for him. He plays with it so often that I ended up buying 2 more shortly after the first one. I did that so I could have them charging while he plays with one. They stay charged for a few days if they’re not used much, but he plays with them all throughout the day. They automatically take a nap after 5 minutes of no activity and wake up if moved within 30 minutes. After 30 minutes, you have to turn them back on. He plays with it so often that I only have to turn it on once or twice a day. They’re easy to turn on. You just hold the power button for a couple of seconds and then press it to cycle through to the color of the corresponding setting you want. There are three different settings that combine movement and vibration. I love that no matter what setting you choose, the movement is always randomized, which keeps him from getting bored with it. We’ve had them about 5 months and they all still work, which is amazing because he’s so hard on them. He grabs them by the string and swings them around, hits them against the hard floor, and basically bumps everything nearby with them. They’re made of extremely hard plastic and the ball is covered in rubber. So it helps keep it quieter when zooming through the house. It’s impressive how tough these things are. The first one I bought just got a crack in it two days ago after he smacked it repeatedly on concrete, so they’re surprisingly well made. They sound like a Hot Wheels or tiny race car. The only noise they make really besides the zoom sound when they’re rolling is the vibrating or if they bump into something. Which if they run into a wall, they change direction like a Roomba does. I’m now buying two more because the strings are just now beginning to fray after about 5 months and because he now wants to have two going at the same time. I’ve also bought him an animatronic lobster and a quail for the same reason as these. They all keep him busy and engaged. If he’s awake, he’s making up games using all three of the toys. The animatronics are the same thing where you charge them up, the nap and wake up when moved, and are randomized. I also have two of the lobsters and quail to charge while he plays with the other. The only automatic toy he has that makes noise is the animatronic quail which is programmed to make real quail sounds but quiet enough to not be distracting. These balls are the incredible and I give them to friends with dogs who all love them as well. If you’ve got a dog a dog that needs it’s mind engaged, I HIGHLY recommend these balls!!! I also recommend looking into cat toys because they’re much more entertaining and engaging than a squeaky toy.

Pet Ball Toy is great!
Color: Red
Absolutely one of the best and most fun toys that our pup has gotten. She is entertained for hours! The interaction helps to keep her active us entertained! It is used by simply pushing the activation button. The material is durable and has survived even when she has chewed it. It is like an energizing bunny! We love it and so does our puppy

Fun while it lasted
Color: Red
I have a 2-year-old Yorkie who absolutely loves chasing balls, so I was excited to try this toy thinking it would keep him entertained for hours. Unfortunately, it didn’t hold up well. As soon as he caught it, he quickly bit the plastic piece off within just a few minutes. I understand that dogs can be tough on toys, especially with their natural hunting instincts, but I expected this to be a bit more durable. It just doesn’t seem sturdy enough for even a small dog who likes to chew and chase. In my opinion, this toy may be better suited for cats or very gentle play rather than active dogs.

Our Yorkie Puppy Loves This Toy!!!
Color: Red
Warning: your pet may become completely obsessed I’ve had this toy for about a year for my Yorkshire Terrier, Gia, and it’s easily the most successful toy purchase I’ve ever made. We even had to replace the first one after she loved it a little too much (chewed the string off), and have since bought more as gifts for friends’ pets. Great toy for small dogs (too fragile for bigger dogs) and active, young cats.) What we love: * Endless engagement: Gia ignores all her other toys and goes straight for this every time * Interactive features: Subtle beeping + changing colored lights + unpredictable rolling patterns keep her hooked * Energy burner: Perfect for indoor play on hardwood floors—she will chase it nonstop * Rechargeable: Battery lasts several hours, even with frequent use * Durability: Holds up well considering how rough she plays Real-life note: Gia will literally bring this toy to me to get me involved—and I have to limit her playtime because she won’t stop on her own. Bottom line: If you have a high-energy dog (or even a playful cat), this isn’t just a toy—it becomes their favorite activity… and possibly their entire personality.
