I replaced the same transformer which was in a pretty harsh environment (I.e., 90% humidity, >100F) It held up well and performed but I wanted to replace it just to make sure everything stayed up and running. Price point is high but the quality is worth it. Highly recommended.

I had a low-voltage transformer die last summer after a lightning strike near my home and needed to replace it. I found this Intermatic model on Amazon and have been very pleased with it ever since. It provides 300 watts of power for my lighting and is totally weatherproof in its design. The transformer I replaced was enclosed in plastic and always had problems with ants and other bugs getting inside. This Intermatic version features a steel enclosure that seals tight against the elements and anything else trying to get in. One thing to note is that this is only the step-down transformer and it doesn't include a photocell or timer that other units provide. This worked well for me since I had a timer controlling the entire circuit. The other nice feature of this unit is the easy selection of output voltage. Inside the unit you have the choice of several output voltages that allows you to adjust for carious loads. For example, if you only have a few lights located near the unit being powered by the transformer you can select the standard 12v setting. If instead you have a lot of light or a longer cable run you can select a slightly higher voltage to make up for the drop in current of the larger load. The ensures that all the lights will be the same intensity along the string. Great product - Well built and a good value!

I added this to my pool equipment to control some rope lighting I had installed along a retaining wall that goes around our pool. It was quite easy to hook it up to our computerized pool controller (Hayward Pro-Logic). The real work was running and burying about 70 feet of landscape lighting cable to connect to the ropelight. It has been connected to the pool equipment for a couple of months, and it is working fine. The only negative is that it does make a slight hum. Given that the pool equipment is outside and away from the pool, it is not a problem.

A professional had to install. Perfect replacement

I had what I thought was a strange problem with my pool light for several years. The light would come on and run for around half an hour without any trouble, it would then shut off for a few seconds and then come back on. It would continue this pattern until it eventually killed the bulb in about a week and a half. Through some research I found out it was likely shutting off because it was sensing an overload or more likely, an over-heat condition.I had an electrician come out for unrelated work and chatted with him about the pool light. He asked if there was water in the fixture and when I told him there wasn't, he immediately told me I needed a new transformer. He told me he could do it for about a hundred bucks + parts but told me if I was comfortable with basic wiring I shouldn't mind doing it myself.Through some additional research I'm seeing these transformers have a useful lifespan of about 7 years or so. My old one was around 15 years old. If you have a pool light that doesn't work, an old transformer, and the light doesn't have water in it, this transformer is a good first step in trouble shooting..Wiring is fairly straight forward with one exception, and the exception is why this is 4 stars instead of 5. I'm going to simplify a little for the sake of brevity. The box has two wires for the high voltage side and two wires for the side going to the light. The high voltage side is a black and a white wire. Simple enough, black to black and white to white. On the low voltage side it has two identical black wires with identical white writing on them. My pool light has one black wire and one white wire. A voltmeter straightened out which was hot but it could've and should've been easier.Update: Still no issues after over a year of use

It’s heavy- heavy enough that it was tricky holding on to it while installing on a concrete wall. Still, it will probably outlast a tornado, like Intermatic typically makes their enclosures. It’s a little buzzy, but so was the Hayward pool light transformer it replaced. Transformers always make a little noise and this one is probably medium-range as far as noise goes, based on the experience with the Hayward and my doorbell and irrigation system transformers. I expect it to last like an Intermatic and I could probably run a car over it without structural damage. I’m only slightly kidding on that.

I purchased this transformer for my outdoor lighting system, and yes it hums very loud. BUT I solved the humming problem and mine now runs almost silent. The problem was the timer switch, like most people I was using one of those Intermatic electronic switches the kind that fit inside an outlet box and you have to program the On and Off times. I believe these timing devices use a Triactor Diode to act as the switch, but being a diode it only conducts in one direction so it cuts the AC Sine wave voltage in half, so instead of getting a nice alternating current of plus 60 volts and then a negative 60 volts, the timer only gives either the plus or negative side so the transformer only sees 60 volts and it is being under voltaged and it HUMS VERY LOUDLY. I replaced my switch with this Intermatic P1121 Heavy Duty Outdoor Timer 15 Amp/1 HP - all is well. Hope this helps others.(and yes I'm an electrical engineer).
