Worked right away, so easy to program! The last system took days to figure out how to program and was never reliable. This one has been up and running for a few weeks now and was easy to program nigh time and morning for on and off, and also has a photocell for auto turn off for dusk and dawn. Happy so far!

This low voltage programmable transformer works great, is easy to install and is very reasonably priced!

Pricy but works great. I have another one so opted to get the same brand. They are easy to install and set up . They are durable. I one I already had has been working with out issues for years.

My electrician recommened that i upgrade my old Malibu transformer. This one did the trick. Solid and nicely made.

Only working for a few days. Was easy to install and hook up. Now working for a couple weeks. Love the on off features. Set mine for on at dusk off in 8 hours. Good price also. UPDATE unit turns on when storm comes in and gets a little dark outside. Then it stays on for 8 hours all day. Guess I'll have to go to a time set

Malibu apparently hasn't made these since 2014. You may wish to google that for yourself. My unit failed within about two months of purchasing it. The failed portion of the unit is the circuit board under the unit's control panel; very likely the rechargeable coin cell battery (LIR2032) that is SOLDERED TO THE CIRCUIT BOARD! All batteries fail eventually. Why in the world would someone design a circuit board with a battery soldered directly to it, instead of a battery HOLDER soldered to it, which would allow replacement of the battery.This unit was well within the 1 year warranty period, so I contacted Amazon. Amazon was quite helpful to me as far as contacting the "manufacturer". The Amazon representative told me it was very likely I would not have to return the unit; the manufacturer would just send me another one. I wish that had been the case, but no, first the manufacturer wanted me to send pictures, which I did. Then the manufacturer asked me to return the unit, and to be sure to pack it up carefully to prevent damage. It would have been one thing to drop by the UPS Store so they could scan a return code, pack it up, and ship it. To be fair the "manufacturer" emailed me a return shipping label, so returning it would not have cost me anything, other than the time and effort of uninstalling the unit, packing it carefully, and mailing it, only to be sent another unit manufactured in 2014 or earlier, likely with another battery near failure.So I emailed the "manufacturer" to say that I didn't want to return the bad unit, but did want them to send me a replacement. A representative of the "manufacturer" called me to discuss this. The short version of what he told me was that they used to send out warranty replacement units without requiring the customer to return the failed unit, but they don't do that anymore. Well ok then.The unit is fairly easy to disassemble. I was fairly positive that the actual transformer within the unit was fine, but that the circuit board and associated control relay were bad; very likely because of a failed battery. So, I opened the unit, wired around the circuit board and relay, kept the overload protection device in the circuit, and put it back together. This resulted in a unit that stays on as long as it's plugged in. It's plugged into a smart outdoor outlet which allows me greater timing flexibility than the timer that was part of the unit.Then, for no particularly good reason, I ordered a replacement battery, and a battery holder, from Amazon. I'll desolder the battery from the circuit board, and solder the battery holder in its place, which should result in a fully functional unit with a significant design improvement.The bottom line, literally, is that I definitely wouldn't recommend purchasing this outdoor lighting power supply.Update:Upon further investigation, the LIR2032 battery on my unit's circuit board tested at 3.7 volts, so there is no issue with the battery. This likely makes sense, primarily because the battery's funtion is to maintain the unit's settings during power outages, so it's not critical to the unit's normal, connected to power, operation. However, my unit's display, which is part of the circuit board, continues to flash on and off, and generally act like it is not receiving power steadily. The remaining possible culprit is the unit's relay, which is connected to line voltage (120VAC), and transmits that line voltage to the transformer when the circuit board tell it to. The rub is that the relay ALSO provides power to the circuit board via the 3 pin connector from the relay to the circuit board. As far as I can tell that relay is not available anywhere :( So, as before this update, my unit's transformer is wired direct, but only receives power when the outdoor smart outlet it's plugged into sends it power.

I am replacing a very old Malibu transformer with this one. The old one has served me for over 8 years. Only reason I’m replacing it is because the timer stopped working. I’ll keep it for a backup and hope this one makes it as long. Now that lights are LED, 200 watts is probably overkill. I’d need 100 2 watt lights to max this out. Crazy since I used to install night lighting and the average bulb light was 25 watts each. Times are changing. Like that it has a dusk sensor to automatically turn on.

Purchased March 2020. Installed under cover well away from any weather influence. Crapped out after about 8 months use. Likely circuit board which is no longer available. Would NOT recommend.

I purchased this Malibu 200 W 12 volt transformer to power my backyard lighting system. I have 21 lights hooked-up in two directions about 150 feet on one side and over 200 feet on another side with the transformer somewhere in the middle near a convenient electric outlet power source. I am using 16 gauge wire with no issues and have power at both ends. Saved significant money over purchase of thicker electrical wire. The unit is very well constructed. The company provides a template that you can cut out and use to drill the mounting screws (provided) which simplifies installation. The slots on the back of the unit fit very precisely to the mounting screws with little variation or play. This makes for very secure installation, but if the holes are slightly off, the unit will not slide down on the mounting screws properly. I used the template and measured to get a good fit. I like the outer "door" that opens which not only adds protection but also aesthetics to the unit as the controls are hidden. The unit is very flexible allowing a photocell (provided) to sense when to turn the system off & on. In addition, the system has an internal clock (must be set) that allows complete on and off control. Finally the system also has pre-sets which are handy. The only thing to point out is that the wires are connected below with one set of attachment screws. I had no issue running two sets of wires (4 total) from the screws, but I can see some manipulation necessary if one was to run multiple sets of wires from this unit. Advise is to mount the wires below first before mounting the transformer in a permanent position as it is easier to work on the transformer / wire attachment that way - at least for me. Then I just place the system on the screws and all is ready to add lights. Very pleased. Great value and system structure. I highly recommend. Marc - SC

For the price this unit is perfect .

Easy to install and working well

still working fine in minus35

needed it
