SUNVIE 300W Low Voltage Landscape Transformer with 2 Independent Control Output Landscape Lighting Transformer with Timer and Photocell Sensor 120V AC to 12/14V AC Weatherproof Low Voltage Transformer

Customer Service is top notch! The unit worked very well, easy to program and has memory so no loss of programming with a power outage. However, I had a unusual issue where the surge protector failed. I wrote Sunvie and had a reply the very next morning. They had me run a few tests and video the negative results. Every morning I woke to a helpful reply from China to further questions I had. Took only 3 or 4 days, and they sent me a new transformer which arrived in 2 days from Amazon. Kind, helpful, punctual help!

I first purchased this 300-watt transformer in September 2025. It worked perfectly for 9 months then started acting erratically. My landscape lights would either come on at dusk but turn off shortly afterwards or would not come on at all. I contacted Sunvie customer service via e-mail, and they responded immediately with some trouble shooting suggestions. When I tried these suggested trouble shooting options it did not fix my problem, so Sunvie sent a replacement transformer immediately. Although I was disappointed that my original transformer had issues, the customer service from Sunvie was fantastic! Note that they have a one-year warranty so my issues at 9-months fell within the warranty period. I originally purchased this transformer because it had all the options I was looking for, most prominently: 1. The 300-watt rating gave me plenty of power to add additional lights later. 2. The two independently controlled zones are what I was looking for to control all my landscape lighting needs. (Zone 1 controls the 26 LED lights on the fence posts along my driveway and the 10 LED lights on my back deck steps. Zone 2 controls the 6 old incandescent lights on my retaining wall and the 4 old incandescent lights underneath the benches on my front deck.) 3. The timing feature I want is "On at Dusk" (with an optical sensor) and "Off at a set time of day". (I did not want one that just came on at dusk and off 4, 6 or 8 hours later.) I wanted the lights to come on at dusk and off at midnight regardless of what season it is. Not all transformers have this feature. 4. A 14-volt connection option for longer runs of lights. I have been very happy with this transformer and the customer service I received from Sunvie. I would recommend this product.

I purchased this transformer to replace one that had failed after about 15 months of service. It works great, as expected. What was not expected is that when I reached out to Sunvie about the failed transformer, they responded immediately, and gave me a few things to try to reset it. When that didn’t work, they asked for my address and promptly sent a replacement transformer. It was out of warranty and didn’t have to do that, but they did without me even having to ask. Sunvie has demonstrated great customer service and their products are excellent. I have three low voltage lighting systems of theirs and this one transformer failure is the only issue I’ve had. I highly recommend their products and the company.

This transformer was so easy to install and connect. The controls are so easy to understand you don’t even really need the manual. The brackets hold it strongly and the connections are covered slightly. I will purchase again if I do more landscape lighting around my property. Worth the money!

Works amazing and the final product came out great. Has a timer for the lights.

Solid quality transformer with two separate zones and multiple timer options (4, 6, 8 hours, or dusk-to-dawn). It works well and feels well built. The only drawback is the lack of a simple on/off switch—you have to cycle through the modes to turn it off, which isn’t very convenient. Overall, I’m happy with the purchase.

If you're looking for a low voltage transformer, this bad boy is the mac daddy! You won't be sorry if you purchase it. Absolutely love it

Today I’m doing this review for another amazing product that can be found on Amazon. I’m genuinely impressed with the SUNVIE 200 W Low Voltage Landscape Transformer! 🌟 Right out of the box, it strikes the perfect balance of durability and intelligent yet down to earth friendly design. The sturdy, weatherproof housing and corrosion-resistant components make a ton of sense for running all year long in harsh outdoor environments . The best part for me is the dual-zone control. Simply press “Zone 1” or “Zone 2” to independently program two areas of lighting. It’s perfect for customizing your garden path lighting and spotlight setup to match your needs. Plus, with five flexible modes — from “Auto on/off” (dusk-to-dawn) and countdown timers to programmable timers. this transformer delivers serious energy savings and light control. The built-in circuit protection and memory function offer excellent peace of mind. If power issues arise, the circuit safely shuts off, and once reset, picks up exactly where you left off. No hassle, just seamless operation . Overall, the SUNVIE transformer is clearly built with both safety and convenience in mind. it’s packed with intelligent - user friendly controls, sturdy protection, and thoughtful features that guarantee both scenic and stress-free landscape lighting. Highly recommended for anyone looking to elevate their outdoor lighting setup!
