LED Strip Lighting 101

The LED technology we use today is safer, brighter, and more energy efficient than any of the traditionally available options. Light Emitting Diodes – or LEDs – are about 80% more energy efficient than traditional incandescent, halogen, and fluorescent light sources, and last about three times longer than fluorescent, and ten times longer than incandescent or halogen lamps. Additionally, because they operate on a low voltage (12VDC or 24VDC) they are the safest option for your project.

Among all the available applications of LEDs, one of the most popular applications is in the form of LED Strip Lights. Where traditional lights usually illuminate from a single point, bulb, or fixture, LED strip lights offer designers and homeowners more flexibility and opportunities for creativity. With hundreds of LED chips running along the length of tape-backed strip, you’re now able to design with lines of light versus a single point or series of dots. And while they’re incredibly attractive and flexible lighting solutions, they can be a little daunting at first.

So before jumping right in, let's explore the details and information you need to know before deciding on the type of strip lights and accessories required for your project.

3. How do you want to control your lights?

When it comes to fully customizable and flexible lighting solutions, strip lights are a great option. However, in order to take full advantage of their capabilities, you will need a controller. These controllers offer a range of functionalities, such as color-tuning, dimming, and turning your lights on and off. Choosing the right type of controller for your needs will depend on your preferences and the specific applications you have in mind. While some controllers offer basic customization options, others like DMX systems provide more advanced capabilities, allowing you to control the movement and sequences of your lights, enabling endless possibilities for lighting design. The primary function of in-wall dimmer switches is to adjust the brightness and turn your LED lights on and off. Our handheld remotes provide a wide range of capabilities, such as changing LED light colors, controlling multiple zones, and activating preset scenes. With app-based controllers, you can easily adjust light colors and dimming levels, manage multiple zones, activate preset scenes, utilize timer functions, and configure presets.

4. How do you calculate the dimensions of your project and decide on the power source for your lights?

Now that you're familiar with your application needs and controllers, you can begin planning the placement of strip lights and the necessary accessories. LED strip lights are cuttable, meaning they can be adjusted to fit specific lengths. However, it's important to note that there is a maximum run length for strip lights. This refers to the maximum distance that a strip light can be laid out with just one connection to a power supply or controller. In the lighting industry, the common maximum run length for strip lights is 16.4 feet. This standard was established to guarantee both safety and optimal product functionality. Considering the maximum run length is important when planning the placement of your strip lights during installation.


Power supplies ensure the efficient and dependable functioning of LED strip lights. These components, also referred to as drivers or transformers, are available in a range of wattages and voltage outputs. This versatility enables power supplies to accommodate various loads and configurations, offering flexibility for installations of any scale.

When determining the appropriate power supply for your LED strip lighting setup, the following simple equation can be used.

Watts per foot x how many feet of strip light being installed = Y
Y x 1.25 = Minimum size of power supply required

If you were installing a full reel (16.4 feet) of N-Series Ultra-Bright Strip Lights the equation to determine the power supply needed would look like this.

2.92 watts per foot x 16.4 feet = 47.88

47.88 x 1.25 = 59.86 watts minimum

In this example a 60-watt power supply is required. It's recommended to plan lighting systems to operate at 80% of the maximum operating output of the power supplies to allow for electrical surges and/or spikes.

Troubleshooting LED Strip Lights: 

If... Then...
Shift in brightness and/or temperature Make sure you did not exceed the maximum strip light series run limit. This will cause excess voltage drop, resulting in decreased brightness and/or increased temperature as the run is extended.
Some lights are not functional Ensure all connections have been attached properly. Make sure that the strips have not been bent excessively, which may cause components and solder to detach from the circuit board.
Lights are flickering First, check for loose connections and that the strip light connectors are attached correctly. Strips vary in width, so it is important that compatible models are used and consistent polarity is maintained.
Secondly, check that a compatible driver is installed. Ensure controller is not on dynamic mode. Verify that +/- connections of DMX systems are not reversed.
Lights are turning on/off repeatedly Ensure the driver is not overloaded. An overloaded driver will trip the internal auto-reset repeatedly, turning the system on/off.
Installation trips main breaker Check wiring for a short circuit. If breaker continues to trip, there might be a short in your circuit. Call us at (888) 503-1317 or email us at for a new driver.
