Turtle Friendly 7" Brass Tiki LED PL006 Path Light, consult your experienced lighting design specialist, IES and Garden Light LED Release New eLearning Course. 1) How many lights will I be installing? Low Voltage Lighting Systems. 2) What is the total Watts and Voltage Amp draw of the landscape lights being installed in an area? Additionally, when considering what wire gauge to use for your landscape lighting design installation, its best to understand that different gauges have their own pros and cons. In addition to 120V LED lights, there are also various LED spots, spotlights and other light sources, which are operated with low-voltage.Usual operating voltages are 12V and 24V.An LED power supply is required to operate the low-voltage lamps on the 120V mains. The LED brightness can't be controlled accurately with low voltage transformers. If you have low voltage halogen light bulbs installed with a transformer, the first thing you need to do before replacing Halogen MR16 light bulbs with LED light bulbs is to find the transformer’s maximum load. The number of lights you can connect to it can be calculated by adding up the total watts of all the lights you want to connect to the transformer which should be less than the total wattage of the transformer. Then, attach the wire to the transformer's terminal screws. For LEDs, even a slight reduction in the voltage leads to a large reduction in light output. Transformer power spec considerations: Calculating Voltage Amps as opposed to Watts, will show you the true power draw on your line, and this is why it is advisable to use this number to ensure you don’t purchase a landscape lighting transformer that isn’t adequate to power your lighting design installation, since it will only cause issues for you down the road eating into your profit and your customers happiness. As a professional landscape lighting designer looking to install and operate a new low voltage lighting system, you need to consider what transformer will be required to convert your standard line voltage outlets using 110-120V into your outdoor low voltage 12V-15V lighting design. What Size Landscape Lighting Transformer to Use to Power Your Design? Our LED Drivers are covered by 2-7 year manufacturer limited warranty. They can also use halogen bulbs, but draw more current than LED bulbs. In addition, LED lamps will turn on at both higher and lower voltages without having their brightness affected like old school halogen lamps would. (10 lights X 30 watts … Our low-voltage landscape lighting calculator will allow you to enter this information to determine the maximum distance from the transformer to the lights. Check other appliances or systems already in use by a circuit before adding your transformer to a particular outlet. You should be able to find this on the body of the transformer itself, in the form of a ‘VA’ number. Best Pro Lighting Low Voltage Transformer 300W – A Perfect Fit For Every Outdoor. The final number determines how large a transformer you need for your system. The only transformer it has for this particular model (QuickFit – Better Homes & Garden) is rated 35watts. C: Waterproof LED transformer, DC12V, from 2.5AMP(30watt) to 8.3AMP(100watt) Step 3: Select the right AMP A: if you ordered 1 reel SMD3528 with 300 LEDs (24 watt), and need a waterproof power supply, then check the Waterproof LED transformer, and choose 2.5AMP(30watt) House current, 120 volts, is reduced by a transformer to 12 to 20 volts, the current needed to operate low-voltage landscaping lights. 120V LED Bulbs; Transformers & Accessories. Choosing a transformer with slightly more wattage will allow you to add a few more lights in the future. A low-voltage transformer converts the 120v of power into the low-voltage that is needed by each of the fixtures of the landscape lighting. Even many lighting manufactures now say that you can “live” with voltage drop. Since often, they have handled and managed a very similar installation using the design techniques desired in your area, to ensure your new installation stays working great years later, and worry free. This is the reason, specific ring lights and can lights usually require low voltage transformer typically of 12 V. Other low-voltage transformer features include motion detectors for turning lights on and off, photo cells to turn lights on at specific light levels and programmable timers. Once that has been considered and calculated with the number of lights on the systems run, you can look for a low voltage transformer that has a higher minimum wattage rating. Before proceeding, visually inspect the transformer for signs of damage or wear. Depending on the lamp or luminaire, both a DC voltage (DC) or an AC voltage (AC) may be required. It’s always advisable to check with the lighting manufacturers territory managers and sales teams prior to purchase, to discuss any other factors and considerations to best determine the proper transformer and wire gauge to use for your specific landscape lighting design system. Note: smaller wire sizes are often more economical and larger wire sizes are stronger, however the smaller ones will also reduce the distance of power being provided to your lights in the ground, and may require conduit to stay safe from dreaded landscaper cuts to your lighting connections. For example, if you plan to use 20 12-watt lights, multiply 12 times 20 for the total wattage. Plug the transformer in.
