    Our most frequently asked questions on low voltage transformer.

    What Is The Ultimate Best Step Down Voltage Transformer?

    With a sheer number of low voltage transformers available on the market, one simply cannot choose the ultimate best because each comes with different and distinctive features that make them unique.

    But if we were to talk about the famous brands that have been leading the market for a long time now, we found brands like Malibu, Netro, pro Lighting, and more heading the top lists of voltage converters.

    Most of them usually come at a reasonable price in exchange for excellent features and peculiarities.

    Which Kind Of Cable Must I Use The Lighting?

    Generally, it is preferred that the users use wires that come in diminished resistance and thick layer. The reason is that cables with increased resistance can create electric crashes once they are destroyed.

    Can I Extend The Light Sensor Cable?

    Normally yes. Some devices come with prolonged cords that reach up to 6 feet. However, it is recommended that you should not prolong the cable by more than 4 meters.

    How Many Bulbs And Lights Fitting Can I Connect To A Low Voltage Converter?

    This will vary from one converter to the other as they are different in wattage ratings. Therefore, depending on the transformer wattage maximum load, you can connect the bulbs and lights to your converter.

    As you have seen on our list, the wattage rating varies from 45 W to 900. What you have to do is, to sum up, all the bulbs you intend to add, and the results should not exceed that of the converter, or else it is not impossible to load it.

    For example, if you have 20W bulbs and your converter has a 300 W rating, you can only connect 15 bulbs. The more bulbs you add, the higher the wattage should be.

    Will The Low Voltage Be Fainter Than Normal Voltage?

    Not really, the low voltage transformer will supply the same light brightness as conventional standard voltage.

    This is mainly because the illumination is not affected by the voltage alternations. The Wattage rating is what determines the lighting luminosity of the bulb.
