DEWENWILS300W Smart Low Voltage Transformer, Compatible with Alexa and Google Home, 120V AC to 12V AC for LED Landscape Lights, Outdoor Lighting, ETL Listed, Waterproof, Schedule and Timer

This is great it really lights up my Malibu lights and a whole lot of them at the same time

I bought two (200 and 300 watt) of these transformers to cover my property's landscape lighting needs. 500 watts gives me plenty of room for the addition of additional landscape Lights should I want them in the future but was less expensive than 2 300 watt devices. I purchased two transformers instead of 1 larger wattage device to save burying cable under a driveway and across grassy areas where there would never be landscape lighting. The transformers (physically) were both well built, easy to hang, and I expect will protect the electronics inside from the weather for years to come. The number of settings for turning the device on and off are ample. I only used the constant on as I coupled both of them to Lutron Alexa enabled outdoor switches so I can fully control when and if devices go on/off. There was a slight difference between the 200 and 300 watt devices in that the 300 watt had a 15 volt option that the 200 did not but that did not affect my needs/design. The one issue that I was not aware of and became a minor hiccup (but thanks to Amazon Prime it wasn't a big problem) was that the transformer will not show an output without being under a load (and evidently a muilt meter device is not enough of a load). I did not see this in the instructions but later saw it on a sticker on the side of the device. I am the type of person who checks everything before going to the next step. Once I attached a well light to the device it functioned flawlessly. I left this extra well light attached (so I could see it lit) after I attached each of my two lines (going each way from the 300 watt device) and as I attached each lighting device down line. This gave me piece of mind knowing if the light I was working on didn't come on the problem was in my local connection to the main line and not the transformer. The brown color of the transformer case matches my home perfectly I hope these transformers continue to look and work as well as they are 4 weeks out.

After electrical storm I was told my old transform was broken so I needed a new one. So this was my solution. But it turns out that after I turned my maintenance over to my service the old one wasn't broken just needed to be rebooted. So this new one is,sitting in my garage waiting for the old one to go kaput.

The transformers themselves have worked pretty well overall—easy to set up, reliable, and they’ve powered our backyard lights without much fuss. But one annoying issue has been the little LED display on the front. After a couple of years out in the sun, the lights start to fade and become really hard to read. I think the sun exposure just wears them down over time, and it makes it tricky to see the settings or tell if everything’s working properly at a glance. Functionally, the transformer still does its job, but the fading display is a small but frustrating design flaw. These units seem built to last around 3–4 years max, which is decent for the price, but not ideal if you want something long-term. Still a decent option for basic landscape lighting setups, but next time I might look for something with better durability and maybe a more readable interface—possibly even a Wi-Fi version for easier control.

For the money it doesn’t get much better

I purchased this item some months ago and because life got in the way, I didn't get to install it until last month. It didn't work! I kept playing with it to see if it was me, and finally gave up. I contacted the seller, and they made some comments but still no luck. They then asked for my address and I got a new one a few days later. This one does work! They were great to work with, responsive and pleasant on the phone. I gave it one star due to it not working, but I'm sure everything will be great now, so I upgraded to 5 stars across the board. All good.

Dewenwils makes great products and I already own one. Unfortunately, their marketing is a joke. This product is described on Amazon as possessing a light sensor and allowing astronomical setting of time. They offer such a product but it is not this one. I have ordered two of the correct products through Ebay and am praying that I will not be disappointed again. They also make so many models that have different features but nowhere do they adequately differentiate the products. Instead, it has taken me hours to figure it all out. DEWENWILS, YOU CAN AND MUST DO BETTER.****************************************************************Dewenwils contacted me after I wrote the review above. There is in fact an astronomical timer function in this model, which one can find in "scenes." The representative who wrote me apologized that its existence or description is nowhere to be found in their manual and promised to write better instructions.I ordered a different model as a replacement and right now it is working fine. However, I cannot comment on its longevity. Many purchasers have written that the transformer dies an early death. I certainly hope not and if that occurs, I really hope the Dewenwils will stand behind their product.

I should’ve bought this a long time ago. So much easier to program from the phone rather than the unit. Easy to use app and it works like the description.
