How to Expand Modular LED Wall Displays Using Single Pack Cololight Extensions

Quick Answer

To expand a Cololight modular LED wall display using single-pack extensions, power off the existing array, attach the new panel's magnetic connector to any open connector point on an existing panel, then power on and tap the Sync button in the Cololight app to detect the added panel. The controller identifies new panels automatically within 10 seconds.

Preparing Your Existing Array for Expansion 🔧

Before adding panels, map out where you want the new hexagons to sit. Each Cololight panel has up to six connection points around its perimeter, and a new panel can attach at any unused edge. Sketch your target configuration on paper or use the Cololight app layout designer. The most important preparation step is to note which edges of your existing cluster are accessible without removing mounted panels from the wall. In practice, the easiest expansion points are the outermost panels in the current array where at least two open edges face outward. SA student setups in smaller rooms often expand vertically rather than horizontally to stay within the wall space above a desk.

Physically Connecting a Single-Pack Extension 💪

With the power cable unplugged, hold the new expansion panel at the desired connection point and align its magnetic connector with the corresponding port on the neighbouring panel. The magnets pull the panels together with an audible click. Check that the panel sits flush: a misaligned magnetic connection causes the panel to display only partial colour or to not register in the app at all. Single-pack extensions ship with adhesive mounting brackets for the new panel. Fix the bracket to the wall first before snapping the panel in, otherwise the magnetic connection pulls the new panel into position but leaves the mounting bracket behind.

Syncing New Panels in the Cololight App 📱

Reconnect power after mounting. Open the Cololight app and navigate to your device. Tap Edit Layout, then tap Detect New Panels. The app scans for newly connected hexagons and adds them to the layout map within 10 to 15 seconds. You can then drag the new panel's icon in the layout editor to confirm its position matches the physical wall arrangement. Save the layout and apply any scene: the new panel will now participate in all effects, animations, and music sync. If the app does not detect the panel, unplug and replug the power cable once and retry the detection process.

FAQ

Is there a maximum number of panels one Cololight controller can manage?

Yes. A single Cololight controller supports a maximum of 12 to 18 panels depending on the model generation. Check your starter kit's spec sheet for the exact limit. Exceeding the limit requires a second starter kit with its own controller.

Can I rearrange existing panels when adding new ones?

Yes. Removing a panel from the wall, repositioning it, and reattaching the mounting bracket is possible. Update the layout in the app after rearranging so the animation patterns reflect the new physical configuration.

Do single-pack Cololight extensions include a power cable?

No. Single-pack extensions draw power through the magnetic connector from the adjacent panel, which chains back to the original controller's USB power supply. No additional power cable is needed unless you exceed the controller's power budget.
