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. ## Features - Designed to supply 12 volts to pool/spa lights, submersible fixtures and outdoor garden lights - Grounded shield between the primary and secondary windings - Built-in circuit protection - 3R Beige metal enclosure with a total of 10 combination 1/2" inch - 3/4" inch knockouts: (2) right side, (2) left side, (2) back and (4) bottom - 7 ¼” inches (19.4 cm) (H) x 5 ¼” inches (13.3 cm) (W) x 4 ½” inches (11.4cm) (D) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B003M60V4O | | Best Sellers Rank | #41,259 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #27 in Outdoor Low Voltage Transformers | | Brand | Intermatic | | Brand Name | Intermatic | | Current Rating | 1 A | | Customer Reviews | 4.6 out of 5 stars 814 Reviews | | Global Trade Identification Number | 00078275024090 | | Included Components | Intermatic Px100 Pool Light 100-Watt Safety Transformer, Beige | | Item Dimensions D x W x H | 4.5"D x 5.25"W x 7.25"H | | Item Type Name | Pool Transformer | | Item Weight | 5 pounds | | Manufacturer | Intermatic | | Maximum Frequency | 60 hertz | | Minimum Frequency | 60 hertz | | Model | PX100 | | Mounting Type | None" or "General Purpose Mount | | Part Number | PX100 | | Power Source | Corded Electric | | Product Dimensions | 4.5"D x 5.25"W x 7.25"H | | Specification Met | Nec | | UPC | 043968898982 078275024090 852673886357 | | Unit Count | 1 Count | | Warranty Description | 1-Year limited | ## Product Details - **Brand:** Intermatic - **Power Source:** Corded Electric - **Product Dimensions:** 4.5"D x 5.25"W x 7.25"H - **Mounting Type:** None" or "General Purpose Mount - **Current Rating:** 1 Amps ## Images ![- Intermatic PX100 Pool Light Safety Transformer, 100W, 12/13/14V | Low-Voltage Safety Transformer for Pool and Spa Lighting, Reliable, Code-Compliant Transformer for Submersible Lighting - Image 1](https://m.media-amazon.com/images/I/61dAIdTnIFL.jpg) ## Available Options This product comes in different **Color, Wattage** options. ## Questions & Answers **Q: Does the PX100 only generate 12v dc? (My wire length requires 14v dc.)** A: The output of the PX100 is ***AC***, not DC - this is an isolation transformer, not a (DC) power supply. As noted, there are multiple output taps that allow you to select 12-14VAC output. **Q: Do i need the switch with this to control the light or is there one built into the intermatic?** A: You need the switch **Q: Will this work with a 300-watt pool bulb** A: It is only rated for 100 watts so you cannot run 300 watts with it. **Q: can I use a regular switch to to turn transformer on,for pool light** A: You may use a residential type wall switch connected to interrupt the primary of the transformer. Wiring methods must conform to the National Electric Code. The load through the switch is less than 1 ampere at the maximum rating of the transformer, but the switch must be rated for no less than the line voltage (120 volts). ## Customer Reviews ### ⭐⭐⭐⭐⭐ No rust and No fuss.

I just installed my pool light and this inverter has 3 power options. 12 volts, 13 volts, and 14 volts. Since I ran an 80' line from the pool light to the inverter, I used the 14 volt line without any issues and when I volt checked the output, it registered at 14.9 volts.
