Rated 2.0 out of 5.0 by GuillermoP62 One power supply solution with serious shortcomings
I had the transformer for about 2 years.
I wanted to have one transformer to drive all my low voltage lights.
I had wanted a system that I could have turn on and off multiple times in a day. That is a standard feature with mechanical clock transformers so I thought the electronic unit would do that and more. I wanted to turn on the lights between 7pm till 11pm and then again at 5am till 7am. This unit cannot do any of that, there is no way to have the unit turn on and off multiple times. So I ended up attaching a outdoor timer to the unit while selecting photocell control on the transformer.
The unit quit working a few weeks ago. Malibu website does not show the transformer and there does not seem to be any support. I opened it up and found that a gecko was able to get inside grow a bit and then got fried, taking out a circuit board.

Rated 5.0 out of 5.0 by POPSELECTRIC Good Design, 2 x 300 Watts on purpose
It is 2 -300watt transformers, and not 1 -600watt transformer, for a reason. YOU CAN NOT PUT 600 WATTS OF POWER ON 1- #12 WIRE, or even worse #14 WIRE!!! 600 Watts divided by 12Volts = 50 Amps. #12 wire is only good up to 25 amps and #14 wire is only good up to 20amps. 300 watts divided by 12Volts = 25amps. Which is why it is 2 x 300Watts, you could not safely put more than 300Watts on one circuit. You don't ever want to max out the circuit either. So even on the 300 watt transformer you should not put the full 300 watts on there. 240 Watts would be 80% which would be ideal, this also limits your amps to 20amps. Therefore, this product is designed with safety in mind, which is why I would highly recommend it.

Rated 1.0 out of 5.0 by Engineer Worked one season and died
I thought my outdoor wiring was the problem, but I finally pulled the unit from under the deck and it was dead. It worked one season and now it's a 20 lb boat anchor. Home Depot should dump this brand!

Rated 1.0 out of 5.0 by tejas disappointed- 600 watt transformer
Have bought & installed & upgraded several Malibu systems over the years of owning 3 homes. Bought the 600 watt transformer for my new home in Florida. Iwas installed under the cover of the house eave. I had it turned off & unplugged forvawhile. When I went to start using it, I plugged it in & immediately my 12/50 watt spotlights went on even with the switch off. Now None of the functions work !?!?!?! Of course, this happened after the warranty has expired. After skimming through other reviews, it seems I am not the only person to which this has happened to. Now if I want to use it, since it has to remain unplugged otherwise lights would be on 24\7, I have to go & plug it in & then remember to unplug. Totally disappointed !!!!!!!

Rated 5.0 out of 5.0 by DIYjunky Don't rate the product based on your inability to read
This transformer is perfect for what it is intended to do. Run two 300 watt runs of lights. This is clearly stated that it is 2 x 300 with timers!! Perfect for front and back set ups, or different sides of your house, or different types of lighting applications where you want to have two runs. I am running my standard garden lighting on one, and rope accent lighting around my porch ceiling on the other. Perfect because I don't have to run the same wire all over creation.

The transformer is an easy one to use. Basically you just need to mount it and plug it in. I mounted mine to the side of the house using the screws that came in the box. I replaced the anchors that came in the box with my own that have a lip around them to prevent them from sliding inside the wall. The transformer has several settings to determine how often and how long the lights come on. The transformer comes with a photo eye to "tell" the transformer when it is dark and light outside. The eye is connected to a long line so you can position the eye wherever you want. I set my transformer to Auto and the lights turn on and off at the perfect time. The transformer comes with two connections so you can run two separate lines. The transformer is a bit bulky and heavy but looks like a black mailbox.
Tips: Have someone help you mount the transformer because it is a little hard to slide the transformer onto the mounting screws.
Fill the holes with caulk before inserting the anchors and put caulk around the screws to make a water tight seal.

Rated 4.0 out of 5.0 Dont base your decision on the reviews
Don't base your decision on the reviews.
1. The transformer works well as advertised.
2. The transformer is good for the price, but wont perform as well as a $300+ unit, so dont expect it to.
The maximum circuit a transformer of this nature can have is 300 Watts per UL Standards. Expect (2) 300 watt runs, don't let the ignorance of the other reviewers influence your decision.
Use simple math to calculate how many watts you are pulling to determine the amount of lights you can run. Most bulbs will tell you their operational wattage eg. 45 watt LED bulb consumes 6 watts. I recommend loading each line up to 80% of max. to account for voltage drop however this is just a personal preference. (300 watts x .80) / 6 watts = 40 (6 watt LED bulbs) I do recommend using online charts for voltage drop over distance / wire guage to maximize the amount of fixtures.

Not really 600 watts, it's basically two 300 watt transformers in one. While that's annoying, I can live with it. What I can't live with is it only functioned for 3 months, then it died.
