Frequently Asked Questions

Do I need a transformer to use my  Low Voltage Lighting?

Yes, Our Low Voltage Lighting requires a transformer. Low Voltage transformers are safe and economical. Your Low Voltage Lighting is not designed for use with 120V power. Do not plug your lighting directly into a 120V receptacle. Use only with Low Voltage Outdoor Power Packs.


WARNING: Risk of fire or electrical shock if used with 120V Power.
Why do low voltage lighting systems require a transformer? You must have a transformer to reduce the 120-volt AC home current to a safe 12 volts AC. Do not attempt to hook up a line of 12-volt lamps directly to an ordinary home outlet without using a 12-volt transformer.
Can you connect a transformer to an electrical outlet with an extension cord? No, it is not recommended.
What is voltage drop? Voltage drop is caused by the electrical resistance of the cable which restricts the flow of electricity. The smaller the cable size and the more lights used, the lower the light output will be along the cable. When voltage drop occurs, you may experience insufficient light output, particularly with the lights farthest away from the transformer. Voltage drop can be minimized by switching to a lower gauge of cable.
What is the maximum length of cable I can attach to my transformer?The total length of cable that you can use, depends on the gauge, however longer runs of cable can result in lower light output near the end of the cable. Therefore, you should use heavier cable or shorter runs to ensure maximum light output. Most important, you must never use cable that is smaller than that listed in the table for your transformer. See the following question for additional information.
Can you mix different wattage fixtures on the same cable run and transformer (e.g., 14-watt floodlights with 18-watt entrance light fixtures)?Yes. To mix different wattage fixtures, add up the total wattage of the lamps. As long as their total wattage does not exceed the output of the transformer, you can mix and match lights

What does the statement "First fixture must be 10 feet from power pack" mean and why? 

You must have at least 10 feet of cable between the first fixture and the power pack to avoid premature bulb burn-out. The cable may be buried, coiling is not recommended.

Why do all my lights blink on and off continuously?The transformer is overloaded. It automatically cycles to prevent overheating. Make sure the total lamp watts do not exceed the transformer rating. Since higher wattage replacement bulbs may have been installed, you may need to examine each bulb instead of using the wattage marked on the fixture.
Is there a positive or negative in the wires or cable? There is no polarity in the wires or cable unless you loop it to the transformer which is not necessary.
How close can I install low voltage lighting fixtures to my swimming pool? For maximum safety, the lights and cable are UL approved to be installed not less than ten feet from the edge of the pool. The power pack must be equipped with a ground shield.
Does Advance Color Lighting have a submersible light for ponds and fountains? Yes, the light has a 20` cable attached and must be used with a ground shield power pack. (For fountains or ponds as long as they contain no aquatic life.) Not recommended for pools, spas or hot tubs.
How many lights can I add to my system?You may add lights to your system as long as the total watts of all the lights does not exceed the rated watts of the transformer.
