Quick Answer

To set up an RGB light bar, unpack the bars, connect them to a USB power source, and attach them to your desk or TV using the included adhesive. Then use the app to customize colors and modes for your preferred ambient lighting.

Why Placement Matters for Ambient Lighting

Getting the best ambient lighting from an RGB light bar depends on where you place it. For desk lighting, mount the bars behind your monitor or along the back edge of your desk to reduce glare and create a soft glow. For TV backlight, attach them to the back of the TV, about 2-3 inches from the edge, to enhance contrast and reduce eye strain in dark rooms.

Keep in mind that the adhesive strips are designed for flat, clean surfaces. If you have a textured desk or a curved TV back, you may need to use additional mounting clips or double-sided tape to ensure the bars stay in place.

Power and Connection Considerations

These light bars are USB powered, which makes them easy to connect to your computer, a USB wall adapter, or a power bank. However, the length of the USB cable can limit where you can place the bars. If your desk setup doesn't have a USB port nearby, consider using a USB extension cable or a powered hub.

Also, be aware that the app control requires a stable Bluetooth or Wi-Fi connection depending on the model. If you're using the app to change colors, make sure your phone is paired correctly and that the bars are within range.

Step-by-Step Setup Guide

Unpack and inspect: Remove the light bars from the packaging and check that both bars and the USB cable are undamaged. Ensure the adhesive backing is intact. If any part is missing or damaged, contact support before proceeding.
Choose the mounting location: Decide whether you want desk lighting or TV backlight. For desk lighting, position the bars behind your monitor or along the desk's back edge. For TV backlight, attach them to the back of the TV, about 2-3 inches from the edge. Make sure the surface is clean and dry before attaching the adhesive.
Clean the surface: Wipe the mounting area with a lint-free cloth and isopropyl alcohol to remove dust and oils. Let it dry completely. Skipping this step can cause the adhesive to fail later.
Attach the light bars: Peel the adhesive backing and press the light bar firmly onto the surface. Hold for 30 seconds to ensure a strong bond. Avoid repositioning after sticking; plan the placement carefully.
Connect to power: Plug the USB cable into a powered USB port on your computer, a USB wall adapter, or a power bank. Ensure the connection is secure. If using a computer, make sure it's not in sleep mode to keep the lights on.
Test the lights: Turn on the light bars using the physical button or remote if included. Confirm that both bars light up and respond to controls. If only one bar lights up, check the connection between the two bars.
Set up app control: Download the companion app from the app store and follow the pairing instructions. Connect the light bars to the app via Bluetooth or Wi-Fi. Keep your phone close during pairing to avoid connection issues.
