Review: No rust and No fuss. It works for my 12v pool lights. - I needed to replace two transformers for my pool. At 300 Watts, this was more than sufficient. I have one 300 Watt light in the pool and another 100 Watt light in the spa. I could save money and buy the smaller transformers with less Wattage capacity but this gave me the flexibility to add more lights and so I purchased two 300 Watt transformers. Input is 120volts AC. Output is 12, 13, or 14volts DC. Most lights are now low (12v) voltage and consume low power so this transformer is suitable for yard lighting or pool lighting; with 300 Watts available, I can imagine that one box could power an entire yard or driveway. My old transformers were twice the size/weight and all rusted on the inside and outside. I chose the PX300S because of the stainless steel housing (hence the "s" designation). The PX300 has a standard steel case that will begin to rust over time. The old transformers were functional but badly damaged from rain/corrosion; I was not going to take chances in my pool and replaced them when I built a new wall around my pool. I am no electrician but the diagram on the inside lid is self-explanatory. I simply knocked out the holes on the side, made a few adjustments to my wiring conduits with some parts from the local hardware store. The box comes with stainless brackets to allow mounting it on a wall. The wiring was a direct-connection using standard electrical parts. My old transformer (circa 1970s) was wired backwards but this transformer was much smaller in form factor and I simply reversed the wires inside the housing to make the connection work for me. Mine is made of stainless steel but painted gray; I have managed to accidentally scratch the housing and unlike the housing on my Intermatic pool timer, there is no rust! The front cover comes off completely and is held on with a single screw seen in picture - this really helps with access and wiring. It isn't an exciting purchase but with a little planning and some electrical conduit, any do it yourself home owner could create an outdoor lighting oasis.
Review: Well made, easy to install and it really isn't that noisy - I purchased this transformer for LED lights that I have installed around the pool. In some of the reviews, the transformer was described as noisy and making a loud humming noise. I was nervous about purchasing this transformer because of those reviews, but I went ahead with the purchase anyway since there aren't many low voltage transformers that are available for installing lights close to a pool for safety reasons. I went ahead and installed this transformer on the back of my pool automation panel. It was very easy to both install the transformer and wire both the high voltage and low voltage side. There are simple instructions included with the transformer. I have Sixteen 5 Watt low voltage LED lights connected to it, so I'm getting close to the transformers maximum rated output, but the transformer has no issues with those LED lights, even when they are connected on about 150 feet of low voltage wiring. Once installed and the unit is operating, there is very little noise from it, even though I have 80 watts of LED lights connected. There is a small amount of noise, but nothing to the level that has been described by some of the reviews. Admittedly, this transformer is about 60 feet away from my main pool area, but even standing close to the transformer when its operating, it really isn't that loud, I guess if it was located close to a sleeping area you might just be able to detect the noise when it is operating, but even then I doubt that it would be annoying. So go ahead and purchase this item, it's rugged, well made and doesn't make that much noise. I'm 100% satisfied with this item.

## Questions & Answers

**Q: I have 2 20 watt led underwater, rgb controller, and plan on more low wattage landscape lighting in the future, would this be sufficient?**
A: This is a 300W transformer. If you choose LED lights you will be able to put a lot of lights on it. If incandescent or halogen bulbs are used, you have to be careful you don't overload it. Are you sure your lights are 20W LED? That is quite a lot of consumption for an LED light. Anyway, you just have to add up your wattage and try to keep it below 300.

**Q: Do thes come wth the power cable?  I don't see it in the picture.**
A: This does not come with the wires/ power cables that run to the light. It also does not come with the wire that comes off the circuit breaker panel. It is simply a step down transformer. But it works just fine.

**Q: I need a 12 volt transformer for a regular 300 watt light (not led) . would this one work?**
A: It would work but would overload after a short period of time. A transformer should not be loaded more than 80% of its rated capacity. So in this case a 300 watt transformer is good for about 240 watts continuously. A 600 watt transformer is good for 480 watts continuously.

**Q: is it designed to be installed outdoors? Or do I need to place it in a weather proof box?**
A: Yes it is. I have two of these for my outdoor landscape lighting in Florida and they have been mounted outside for the last 3 years and are operating perfectly and still look like new. They are designed to be outside.
