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

This is probably the easiest transformer to program that I've ever used. 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

Works well, easy to program. Gets the job done.

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.

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!

I really like how this has a door cover on it with none of the LED lights or anything exposed. It makes it blend in much nicer and not noticable. Everything else available now seems to have everything open on the face which is an eyesore.Overall this unit has worked great, however any of the photocel-related functions are basically useless. I really liked the idea of being able to set the photocell, use a 4 hour or 6 hour timed off and not have to worry about anything, but for some reason it just never works right. Woke up to my lights turning on in the middle of the night multiple times, or turning on/off when they shouldn't be otherwise. Very confusing.The only setting that really works is timed on/timed off, which is kindof annoying because every time the power goes out for more than a minute the clock and timers seem to get a little funked up, with the AM/PM switching on the timer settings or the clock falling behind. This wouldn't really be an issue if it werent for the fact that it takes FOREVER to change the time. You can't just change AM/PM, you have to literally hold the arrow down for a full 2 minutes just to get +12 hours on the clock to get the time back to the right AM/PM setting. Very weird and annoying.If those two bugs were improved this would be a winner all around. Overall I'd buy this again literally just because it's got a door and hides itself nicely.

We purchased this power supply to power our outdoor lighting when the original one failed. I really like this power supply as it was reasonably priced and has a built in circuit breaker. This is a waterproof supply which gives you options for how long our lighting is one each day. It was very easy to install and powers all our landscape lights with power to spare.
