I've been through about 4 of them of other different brands. They all seem to burn out after about 10 to 15 years. I thought I'd give this a try. So far I am happy with it. I weld a stand for it, mounted in the ground keeping the unit elevated above the ground by about 8 inches. The thing that I was most impressed with is I programmed it in my workshop with nothing attached, and then took it to the jobsite about 5 days later and install it and it had maintained its programming from the day I had set it up in the workshop are areas prone to power failures. The ones that I've had before of always had to reset after a power failure. This one has a memory bank that keeps the settings memorized. I use a photo on timed off, which is just one detent position with the dial auto on timed off. All I have to do is set the time. And then turn the knob to the very first position and it's off and running couldn't be happier. The doors attractive. It is waterproof, but I usually put a plastic bag over these to keep moisture out. You can hook up 2 wires separately by using each side of the hold down screws and square washers. That way you can put the transformer in the middle of your circuit and running 2 separate branches. I use this to light up 12- 5W LED M-16 BI-pin lamps in waterproof fittings and couldn't be happier. The brilliance of each bulb is equal all the way across the hundred and 50 foot spread of wire which is 16gauge. I simply place the photosensor on top of the unit itself and it works just fine on at dusk off at midnight couldn't be happier Review: Above board in reliability! - I've got two of these units that have been in use for several years now, both operating without any problems whatsoever, so I expect this one to do the same. We get heavy snow annually, so I added a small plywood cover above each unit to keep the snow off the top. These are awesome, worry free, reliable units, and I don't have to babysit them at all! I had to return my last order, an off brand that failed within three months. Though my return is being processed quickly and a refund to be issued I was very disappointed more in myself for not sticking with what works. If it ain't broke, don't fix it. If you need a reliable low volt outdoor light timer, this is what you are looking for, period. don't waste your time with the cheaper units! ## Features - Advanced Setting Modes: Our landscape transformer offers a comprehensive range of five modes, ensuring unparalleled functionality and energy efficiency. Including (a manual on/off mode) (on at dusk, off at dawn) (on at dusk, off at 4/6/8/10 hours) (on/off at the specific time you set) (on at dusk, off at the specific time you set), which is sufficient to meet any of your needs and maximize energy savings - Enhanced Protection Mechanisms: Our transformer incorporates built-in circuit protection to safeguard against overload, automatically disconnecting the power supply to prevent device damage and prolong product lifespan. Additionally, the memory function preserves the selected mode during power outages, ensuring uninterrupted operation upon restart. - Effortless Dusk-to-Dawn Sensing: Featuring a detachable photocell sensor, our landscape lighting system seamlessly transitions between day and night operation. Simply set the knob to AUTO mode, allowing the sensor to activate lights at dusk and deactivate them at dawn, simplifying setup and optimizing energy usage. - Precision Countdown Timer: Offering light-controlled timing functionality, our transformer includes a countdown timer with options for 4, 6, 8, or 10-hour activation periods. In this mode, lights automatically turn on at dusk and switch off after the designated duration, promoting energy efficiency and convenience. - Weather-Resistant Design: Constructed from durable, waterproof, and high-performance plastic materials, our transformer is engineered to withstand various adverse weather conditions. Its corrosion-resistant properties ensure longevity and reliability, making it suitable for prolonged outdoor use in any environment. - Smart Protection & Usage Guidelines: While our transformer can handle a maximum load of 120W, we recommend using of 90W for best results. This practice prevents the system from running at full capacity, ensuring greater stability and significantly extending the product's lifespan. Moreover, the built-in reset switch automatically activates in case of a short circuit. After troubleshooting, a simple press of the reset button will have your system running again safely. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B01IOZ8810 | | Best Sellers Rank | #16,534 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #8 in Outdoor Low Voltage Transformers | | Brand | Malibu C | | Brand Name | Malibu C | | Customer Reviews | 4.0 out of 5 stars 2,556 Reviews | | Included Components | 61" cable lenght photo sensor, 120W transformer, Instruction, Screw, Anchor Wall | | Item Dimensions D x W x H | 3.4"D x 4.7"W x 7.5"H | | Item Weight | 2.95 kg | | Manufacturer | Malibu | | Model | 8100-9120-01 | | Mounting Type | Wall Mount | | Number of Items | 1 | | Number of Packs | 1 | | Part Number | 8100-9120-01 | | Power Source | Corded Electric | | Product Dimensions | 3.4"D x 4.7"W x 7.5"H | | Specification Met | ETL | | UPC | 859794006176 | | Unit Count | 1 Count | ## Product Details - **Brand:** Malibu C - **Power Source:** Corded Electric - **Product Dimensions:** 3.4"D x 4.7"W x 7.5"H - **Mounting Type:** Wall Mount - **Specification Met:** ETL ## Images ![Malibu 120 Watt Power Pack with Sensor and Weather Shield for Low Voltage Landscape Lighting Spotlight Outdoor Transformer 120V Input 12V Output 8100-9120-01 - Image 1](https://m.media-amazon.com/images/I/71w-fp8i-NL.jpg) ## Available Options This product comes in different **Wattage** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Easy to program and once programmed holds its memory in case of power failures *by D***P on May 29, 2025* This is probably the easiest transformer to program that I've ever used.

They're garbage. I don't know what the issue is with them but I've had several of them now that I purchased and one of them only lasted maybe a month before the timer went out on it then it completely died and the lights would flick on and off. They replaced it the new replacement one is acting up after several months it smells like electrical when you're outside and if you touch the box it's red hot. The lights are dim. I have a 200 watt box every time it comes on the lights are flickering and don't want to work right. Of course I'm past the return window for both of them now because it's been a few months and these things are junk. They make you get a hold of the company the company wants all kinds of information then they want you to send it back to them to see if they can fix it they're just junk.
