FAQ: How Do I Choose the Right Power Supply for my Light Fixture?

Global Voltage Map

3. Calculate Your Fixture’s Total Wattage

The total wattage of the light fixture should be at least 10% less under the wattage of the power supply. In other words, do not push beyond a power supply’s maximum capacity. This can cause your fixture to overload. Be sure to add wattage together when powering multiples fixtures using the same power supply. Wattage for each fixture can be found on its product page, or you can contact us for help.

4. Select your Dimming Option

The most popular dimming option is 2-wire/Forward Phase/Triac dimming due to its smooth performance. The lifespan of an LED can reach up to 50,000 hours or 15 years when installing fixtures on a dimmer. 0-10V, an output range that controls dimming from 1V (lowest dimming level) up to 10V (highest light output), allows LED fixtures to function using less energy while also providing dimming capabilities. Lastly, 3-wire allows for a continuous, flicker-free dimming performance down to 1% without drop out or pop on but will require a third line voltage wire.

5. Consult with a Licensed Electrician

We encourage that you consult with a licensed electrician to confirm the right power supply for your light fixture or any electrical needs as a safety protocol. Once you’ve cleared your space’s requirements, you can contact our sales team for questions about our fixtures and compatibility.
