About This Product

The landscape transformers are Hampton Bay's lowest profile slim line power units which can be easily concealed after installation. These units are based on a potted toroidal core design that eliminates annoying buzzing sounds while offering the highest efficiency possible. Our Hampton Bay SL units meet the Department of Energy DOE mandatory requirement efficiency rating of VI. Utilizing state of the art sensing circuits, our transformers provide dual safety functions that detect and react to a system overload or a short circuit condition in a landscape installation. Hampton Bay power packs provide convenient features and flexibility to design simple or more elaborate landscape lighting designs. The transformer includes a photocell and digital timer, a ground shield making it safe for use with submersible lights. The units are equipped with dual voltage output terminals (12-Volt and 15-Volt) which help compensate for voltage drops in high-Wattage / longer wire runs as well as to help reduce cable loss when using 15V LED fixtures.

                      We recommend using it outside or in a garage because if can be a fire hazard if melting ever occurs

                      By|May 12, 2026

                        Yes it can as long as its like a garage, or on a deck or porch but never in a kitchen etc.

                          This is a tiny cute little transformer. We hooked it up to 6 landscape lights with no issues.

                          Very Counterintuitive
                          This is without a doubt, the most confusing low-voltage transformer I have ever used. I have installed several different brands in this one is very counterintuitive. Also, once you finally get it figured out either daylight saving time hits or the power goes out and it reverts back to 12 o’clock.

                            Newest batches don't retain programming and reset clock back to 12 after power interruption
                            These used to be very good transformers but I noticed I was getting call-backs from homeowners who said their lights weren't coming on again after a power outage. This was a surprise because the logic board/LCD screen on these used to have a CR2032 battery that would retain all the clock and programming but that is no longer the case. Both these and the 200W units just have an empty spot where the battery used to go. I hope this is just a bad batch and not a purposeful design decision but I have to return all the ones I have as they are useless unless you put in an outdoor timer ahead of it and put them in test mode. Shame on you Home Depot.

                              I had this transformer used to add lights to my patio steps. The delivery was quick.

                              I installed this voltage transformer on my one acre lot in Phoenix in April and it’s working like a charm. I am using the built-in choice of starting the lights when the automatic light senses “dark”, and the “shut lights” at 11:00 PM. The neighbors are raving about it! I am planning to add more lights to this 300-watt work horse. Only one minor fault because the sun in Phoenix is so brilliant; I have to block the rays if want to see the LED panel.

                              This is awesome no Wi-Fi connectivity to fail simple straightforward, more than enough power, power deck lights and 8 landscape lights overkill, but the last two I bought are still running strong after 5 years on my Other home

                              Broken parts
                              Open the box and multiple broken black plastic fill out everywhere. Transformer was not packaged very well, which caused plastic for light center to break all over in the box now unusable. Disappointed.

                                You can do this!
                                I'm not an electrician and I don't play one on tv. Home Depot and Hampton Bay made it easy to dress up my home and make my wife happy. Instead of mounting the transformer to my brick home exterior I bought a weatherproof box that allowed me to protect the transformer and hide it in the landscaping. I installed the 4-light system after dinner and it took me about 45-minutes, but it turned out to be pretty easy. The optic sensor is mounted to the post and I hid the cables under the mulch. Now I need to adhere the wire from the one light to the underside of the concrete porch. That will be easy.
