Gardencoin Solid Brass Outdoor Landscape Spotlights, 12V Heavy Duty Low Voltage LED Spot Light Waterproof for Garden and Yard Up Lighting, Bronze Accent Lighting Fixture Without Bulb, 6 Pack

What kind of power cable and transformer should I need?

e.g Suppose there is a set of 4 spotlights (each 3W) and 2 path lights (each 4.5W) that need to be installed in the garden, How do you choose the cable and the transformer?

1. Add the individual light fixture wattages for all lights. 4*3W+2*4.5W=21W

2. The typical distance between two lights is 6-8 feet, but closer or farther is ok too. Based on the above diagram, 6 lights total watts in 0-60 should choose 75-100ft 16AWG power cable.

3. The transformer is large enough to support the Total Fixture Wattage, it should be the best usage within 80 percent of the rated capacity. So in this case a 45W transformer is enough.

Note:

• Bulb： In the 1-pack item we include a standard 2700K-5W bulb. Other brass spotlight series use a GU5.3 bi-pin base, you must purchase a matching MR16 bulb separately. For MR16 bulbs, it is important that you choose a pointed bi-pin rather than a flat bi-pin, as flat bi-pins may prevent the bulb from being installed and cause damage to the fixture.
• If you need to mount it on a tree trunk or outdoor wall, purchase a mounting plate, 1/2 NPT thread size, and search keywords: Mounting Plate for Landscape Spotlight.
• Price： If you buy multiple packs, you will get more discount than single pack.
• Projection： Beam angle is not limited by the product, you can choose different angles of the bulb according to different use scenarios.
• Working： The working voltage is 9~17V, so the spotlight usually needs to be connected to a 12V transformer to work properly.
