In the U.S. the voltage for electrical appliances ranges from 110 – 120V and at 60 Hz. If your electrical appliances are from another country with a different voltage output, you’ll need to get your hands on a power converter. Having an adapter is not enough for some appliances to work unfortunately. For instance, having a 220v appliance plugged into an outlet that is 120v wouldn’t work properly with the lack of voltage. On the other hand, plugging a 110 or 120v appliance into a 220v outlet could potentially lead to issues such as frying the components, overheating, and worst case, starting a fire.

Many appliances in the U.S. and Canada would have a UL certification to indicate that the product has been rated and approved for safety in U.S. and Canada. There would be a need for a power adapter if you plan to use our appliances outside of the U.S. For that, you’ll need to check the location’s voltage and whether or not there will be issues.

Now for our LED lighting fixtures, some of them allow you to connect multiple lighting fixtures to one power adapter. However, an issue that can come up is overloading the adapter and possibly breaking the power adapter itself or the lighting fixture. So, consider how many LED lighting fixtures you’re going to connect to one transformer. The wattage tells you how much power it can output, but our transformer has an 80% capacity limit meaning that there’ll be a limit to how many lighting fixtures before the transformer will overload. With our LED Puck lights, the wattage ranges from 2.0 to 3.0 watts. At 80%, our transformer, the LEDTF-1A, can output 9.6 watts which can handle 3 LEDP-030 and 4 LEDP-060. With the LEDTF-2A, the wattage jumps from 12W to 24W, allowing you to connect additional lighting fixtures to the transformer.

Hopefully, this bit of knowledge will aid you in considering what you need and how much you need. We want to make sure that people are familiar with voltages and wattage so they can avoid overheating or damaging their appliances.
