Frequently Asked Questions

How many bulbs can a transformer light?

This depends on the wattage of the transformer that you are using. Some have a higher wattage, thus allowing them to accommodate more bulbs, while others can only handle a few due to low wattage. The best way to know how many bulbs can be connected to your transformer is by calculating the total wattage of all the bulbs.

For example, if you have 20 bulbs and each uses 30 watts, you can get the total wattage by simply multiplying the number of bulbs by the watts that each uses i.e. 20 x 30 = 600 watts. It is advisable to buy a transformer that has a wattage that is slightly higher than the total bulb wattage. For instance, the above example would require a transformer with 675+ wattage.

What will happen if I overload my transformer?

A majority of transformers have a safety feature, which breaks the circuit when there is an overload or a short circuit.

What does LED stand for?

It stands for Light-Emitting Diode. Most LED bulbs have semiconductors, which emit light or infrared rays when an electric current is passed through them.

Electronic or magnetic, which transformer should I go for?

This depends on the budget that you are working with. If you want a budget-friendly transformer the electrical option will do. But you have to keep in mind that electrical transformers operate with noise.

Final Verdict

By using the transformers on this list, you will have a chance to illuminate your outdoor environment and turn a place that was once dull into a bright paradise. The pieces of equipment listed above are safe, so you can use them without fretting.
