To use our LED light strips, you need to first have a 12V DC power source. If you don’t already have one, HitLights sells adapters that convert the 110AC power in a U.S. outlet, to a usable 12V DC current. If you have one of our LED color changing light strips, you will need a controller to change the color of the strip. We also have other options for controllers, dimmers and power adapters in our LED Light Strip Accessories section. All of these accessory options will help you get the most out of your strip light.
