I used it to replace a transformer that I installed a year and a half ago. That one had a digital read out and good reviews on desertcart. It looked similar to something you'd find at Lowe's or home depot. Well, after a year and a half the digital display failed and the one year warranty was expired. There was nothing to do but buy a new transformer. After that experience the lifetime warranty and replaceable timer on this unit appealed to me. I had never heard of the brand, but the reviews were great and seemed real, so I went for it. I wasn't disappointed. This is the best transformer I've ever installed or even worked with in my 15 years as an electrician. The construction is excellent, the design is even better with a plug in timer unit and the photo cell tucked safely behind the sturdy door lens to keep it from the elements. I totally loved that detail! Here in Texas most photo cells last 3 years max, thanks to the sun roasting them all summer long. I don't see that being a problem with this unit. It gets light through the lens on the door, but it's completely out of the weather. Genius. Function was fine so far. My client was happy. And I'm not worried because I know I installed a quality piece of equipment with a lifetime warranty just in case. I'll only be using Volt transformer in the future. Review: Solid Product - I really like this brand. The packaging was great, transformer was well protected. The box was damaged on one side on delivery but, because of the great packaging inside, the unit was not affected. I love the stainless steal case and the easy of installing it. I am not a professional landscaper but, did my research and this product came up over and over. It is well worth the money as it will last for years to come. I replaced a 20-25 year old system that had a small plastic transformer. I did have to return this one because I had miscalculated the size I would need. I did order the correct size and it was very easy to swap out. This one comes with a timer that you plug into the inside of the transformer and everything closes up securely inside the weatherproof box. I will add pictures later to this review. Don’t hesitate to buy this unit. ## Features - LOW PROFILE MAGNETIC TRANSFORMER - To make this transformer slimmer, lighter and simpler to install, we eliminated unnecessary voltage taps. Just use the 12V and 15V taps; that's all you need for a medium-sized LED landscape lighting system. The 15V tap enables you to compensate for voltage loss on a long or heavily-loaded wire run. Note: Never load any transformer to more than 80 percent of its capacity (240W for this model). - MODULAR TIMER WITH PHOTOCELL INCLUDED - Visible through the housing window, this timer can be set for simple dusk-to-dawn operation or set to turn off after a certain number of hours. The photocell is built into the timer. - EASY TO INSTALL - The clamp-type terminal blocks are impressively easy to use - taking seconds to connect - compared to many minutes of frustrating work for standard terminal blocks. Just insert the stripped wire and close the clamp! Accepts up to 10-gauge wire. - HIGH PERFORMANCE - This low voltage transformer's toroidal core allows for more reliable, efficient, cooler and quieter operation than comparable EI laminated types. It's also superior to electronic transformers, which may not be compatible with LED circuits, suffer from extensive voltage loss, and are subject to overheating and premature failure. - LIFETIME WARRANTY - With an industry-leading warranty, this Slim Line Transformer is designed for a lifetime of worry-free use - we guarantee it. The core, stainless steel enclosure and all electrical components are backed by our lifetime warranty. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07PMFSH3J | | Best Sellers Rank | #51,878 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #38 in Outdoor Low Voltage Transformers | | Brand | VOLT | | Brand Name | VOLT | | Customer Reviews | 4.8 out of 5 stars 378 Reviews | | Included Components | timer/photocell included | | Item Dimensions D x W x H | 3.7"D x 5.5"W x 15.33"H | | Item Weight | 13 pounds | | Manufacturer | VOLT Lighting | | Model | VTR-300SL-SS-ZON-CA-FBA | | Mounting Type | Wall Mount | | Number of Items | 1 | | Part Number | VTR-300SL-SS-ZON | | Power Source | Corded Electric | | Product Dimensions | 3.7"D x 5.5"W x 15.33"H | | Specification Met | ETL | | Unit Count | 1 Count | | Warranty Description | Lifetime | ## Product Details - **Brand:** VOLT - **Power Source:** Corded Electric - **Product Dimensions:** 3.7"D x 5.5"W x 15.33"H - **Mounting Type:** Wall Mount - **Specification Met:** ETL ## Images ![VOLT 300W Slim Line Low Voltage Transformer (12V/15V) with Timer/Photocell - Image 1](https://m.media-amazon.com/images/I/51pOPBloHkL.jpg) ## Available Options This product comes in different **Wattage, Set** options. ## Questions & Answers **Q: How can I troubleshoot the power and electrical on this transformer?** A: Confirm the unit is plugged into a working 120V outlet. Check your home's breaker panel and GFCI outlets nearby for tripped breakers or reset buttons. Inspect the 25A magnetic breaker on the secondary side; press the reset button if it has tripped. **Q: How can I troubleshoot the timer/photocell?** A: Make sure the timer/photocell module is fully seated in the interior receptacle. Check that the photocell isn't exposed to light sources. Verify the control dial is not in the OFF position. Cover the photocell sensor completely to simulate darkness. **Q: How can I troubleshoot the wiring and connections?** A: Confirm all fixture wires are properly clamped in the terminal blocks. Check that you're not exceeding 80% of the 300W capacity (240W total load). Make sure you're connected to the correct voltage tap (12V vs. 15V) for your fixtures. **Q: How can I troubleshoot if there's no output or lights aren't coming on?** A: Test with a single known-good fixture connected directly at the transformer to rule out a wiring run issue. Check individual fixtures for failed bulbs or connections. Ensure the transformer lid is properly closed.. **Q: How can I troubleshoot the transformer's placement and environment?** A: Confirm the transformer is mounted vertically as intended, not lying flat. Make sure the power cord reaches the outlet without being stretched, pinched, or run through standing water. In very cold weather, give the unit a few minutes to stabilize. ## Customer Reviews ### ⭐⭐⭐⭐⭐ New favorite transformer *by P***E on July 20, 2019* Listen, I'm a professional master electrician in Texas and this is the only landscape lighting transformer I'll be using in the future.

I researched and researched and landed on this 300w low profile unit. It not only looks great it is highly functional and sturdy and very well made. Have the 5 separate taps was key for me as I had a 3 run immediate need and a 4th that I am still noodleing on. Which leaves me with a spare yet-to be determined run. The 12v and 15v options for each run are also awesome. If you need the extra push of power on those extra long runs the 15w is there to save the day. I did have a few exchanges with their tech support around output as I needed mor info. They responded fast with plenty of info. The 300w total gives you plenty of power assuming you are using 3w & 5w LED lights. I know.... It is expensive. However, if you take into consideration the expandability and power and 5 tap run it is hands down worth it. I recommend this as a great transformer. ## Frequently Bought Together - VOLT 300W Slim Line Low Voltage Transformer (12V/15V) with Timer/Photocell for LED Landscape Lighting - Wirefy 12/2 Low Voltage Landscape Lighting Copper Wire - Outdoor Direct Burial - 12-Gauge 2-Conductor 250 Feet | Landscape Lighting Wire | Low Voltage Wire 12/2 | 12/2 Landscape Wire - Wirefy 12/2 Low Voltage Landscape Lighting Wire - 12-Gauge 2-Conductor 100 Feet, Copper --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.be/products/121981643-volt-300w-slim-line-low-voltage-transformer-12v-15v-timer](https://www.desertcart.be/products/121981643-volt-300w-slim-line-low-voltage-transformer-12v-15v-timer) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-09-24*
