MALIBUPower Pack 200watt Low-Voltage Weatherproof Transformer with Photo Sensor for Low-Voltage Landscape Lighting

Great product! Fast and easy installation.

Just received today. Took me 10 mins to install. Very easy to set timer. Just make sure its am or pm

I have two of these now, one for my front yard and one for the back yard. I have had one for about 2 years and the second one for a year now. Multiple settings and does great in the summer and winter.

My Hampton Bay low voltage power supply for my outside lighting died after we got almost 2" of rain last week. Now the unit is almost 1.5 years old but water got in it and Poooof! I looked at getting another but then came across the Malibu unit. I like that it has a weather-proof door and the timer and programming buttons are safe inside, unlike the Hampton Bay unit which is exposed to the elements (even though it is OK for outdoors). The summer heat and sun here in AZ are harsh and the plastic covering failed causing the water to enter the unit and die. Looks like this Malibu unit was sent back, missing some parts for mounting "hence the 4 start rating" but I got it covered. Last night at dusk the sensor worked and the lights came on... works for me. We are suppose to get rain tomorrow and will put it to the next test.

These are nice units as they give you a lot of lighting options

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.

This transformer is head and shoulders above the old-school transformers that Malibu used to put out. i was skeptical that this would be much better but it had the features i was looking for, had a good price point and had pretty good ratings. i am not disappointed in my purchase. The photo detector works as advertised and my lights come on at dusk just as they should. and i have it set to turn off at a designated time in the evening. or i can have it run for x-number of hours after it turns on too or set it to turn on/off at designated time. I'm real happy that it has the photo on/timed off feature. this was exactly what i was looking for. It is quiet (my old transformer hummed so loudly that i could hear it inside my house), has a super easy to use interface and cool testing settings. Very happy!
