Trex deck lighting hub8/8/2023 If the transformer cable does not reach the splitter, then you may need a wire extension cable, one which is designed to connect after the splitter. More importantly, do not use an extension cord between the electrical outlet and the transformer, rather, connect the transformer directly into the power outlet. Leave them loose so you can maneuver them as you insert the Lighthub plugs. Also, don’t fully attach the splitters to the joist. You’ll get a 5’ wire with each light fixture from Trex, so all you need to plan to buy are the splitters and the wires that connect each splitter together. Wire splitters transform one female connection into several, which makes adding them necessary along every post base where you want lighting. Some systems, such as the Trex Lighthub® system, use wire splitters to eliminate the need for cutting and splicing. If the system you’re installing uses a proprietary plug and play installation system, it’s normally appropriate to cut and hardwire the connections (but always check with your manufacturer for more information). If you use a thicker (or lower gauge) wire you will minimize the chances that this can happen. In basic terms, the longer the electricity has to run the more energy it loses at the end of the run. The issue this potentially solves is a problem called voltage drop. One last power supply consideration: if you have an excessively long wire run (for example, over 300 feet) you might consider sourcing your own wire and stepping up to 16GA UL-listed outdoor rated 2 conductor wire. For this reason, it’s highly recommended to use the same brand transformer as the light fixtures and to stick to one brand of fixtures. Also, it’s absolutely critical that you never mix AC and DC fixtures on the same circuit. AC vs DC) your lighting fixtures take, as the wrong voltage type can cause major component failure and other performance problems (and may even void your warranty). It’s important to know which type of voltage (i.e. The other option is to use transformers that change the voltage type from AC (Alternating Current, like your home uses) to DC (Direct Current, like your cell phone charger) while reducing the voltage from 120V to 12V. Some, often less expensive transformers, are simple “step-down” units that simply take 120VAC and step it down to 12VAC. One important note: Not all 12V transformers are created equal. Most installations call for 12V transformers, so you only have to concern yourself with ensuring the transformer you choose can withstand the total wattage of all connected lights (most manufacturers have more than one sized transformer). Low voltage deck lighting systems will require a deck lighting transformer, which is used to convert the ordinary household “line voltage” (120V) produced by an electrical socket. Overloaded transformers can fail prematurely and potentially cause fixture performance problems. Trex also has an interactive online Lighting Transformer Calculator to help make sure you don’t overload the transformer. Installing Trex deck lighting can make this easy because the LightHub connection system allows for the addition of a variety of accessories, including splitters, adapters, and customizable lengths of extension cabling. Once you’ve done that, you’re ready to start making approximate measurements for the length of wiring necessary to run your lights, and how many transformers you might need for your project. Start by identifying the locations of AC power sockets for plugging in the transformer. Planning your deck lighting installation prior to installing any low-voltage deck lighting is essential to making sure you achieve both of those goals. Each light will need to connect with a 12V transformer. Develop a Lighting Planįirst, you’ll want to position your lights so that they’ll illuminate the appropriate areas. And unless you need to run additional line-voltage circuits to feed a transformer, you probably won’t need an electrician or contractor for even a fairly elaborate deck lighting installation. Installing low-voltage deck lighting is inherently safer than installing household line voltage fixtures inside your home. Learning how to install low-voltage deck lighting is fairly simple, provided only that you use a low-voltage lighting system and carefully read all manufacturer instructions. Whether you’re looking to add ambiance or functionality to your outdoor space, the right deck lighting is one of the most impactful enhancements you can make to your deck. For any home project, be certain to follow local code and permitting requirements.
