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 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!
