Hello everyone, I would like to retrofit my IKEA Billy shelves with LED lighting to enhance their appearance and improve visibility for books and decorative items. Now the question is, what is the best approach: Which type of LED strips work well for Billy shelves, how can I mount them effectively without damaging the shelf, and what power supply is recommended when lighting several units? I am also interested if anyone has experience with integrating switches or motion sensors into the shelving, and if there are any considerations regarding wiring or safety. I appreciate any tips, recommendations for suitable products, or assembly guides. Thanks in advance!
Hello Goklo, I would recommend flexible 12V LED strips. You can attach them using double-sided tape, which is often included with the LED strips. Just make sure the power supply is adequately rated – that means the wattage should match the length of the LED strips. You can run the power cable to the back of the shelf. Inline switches are available. Motion sensors are also available as kits.
For precise implementation: Suitable LED strips should have a color temperature around 3000-4000 Kelvin for a comfortable lighting atmosphere in the living room. The shelf material (particle board) allows direct attachment of the LED strips to the back panel or under the shelves. It is best to use strips with an adequate protection rating (at least IP20). For power supply, power adapters with overload and short-circuit protection designed for continuous use are recommended. A simple solution for switches is a toggle switch in the supply line; motion sensors require more planning regarding wiring and placement, especially due to the live wiring inside the furniture piece.
Hello Goklo, I focused a lot on clean, almost invisible wiring for a similar retrofit. My approach was: First, measure the shelves and get LED strips with adhesive backing. I mounted the LED strips underneath the shelves because this lights up the inside of the shelf without causing glare. It’s important to ensure the LED strips don’t generate too much heat – 12V products are usually fine.
I used thin PVC-insulated cables for the wiring. Self-adhesive plastic cable channels help to neatly hide everything and protect the cables from abrasion. I positioned the power supply behind the shelf and connected it via a power strip with short-circuit protection.
Regarding switches or motion detectors: You need motion detectors if you want automatic lighting that activates only when movement is detected. These should be compatible with 12V DC. Installation locations are either on the front or the side of the shelf where they remain unobtrusive. Make sure to connect the cables correctly and securely. There are small differences in safety standards to consider – for example, the load capacity of switches and the current rating for LED strips.
Do you already have an idea of how many shelves you want to light? Then I could also recommend the approximate power requirements and cable dimensions.

Do you already have an idea of how many shelves you want to illuminate?Hello TEBILO, thanks in advance for your input! I am currently planning to light up two Billy-style shelves, each with five shelves, so basically 10 LED strips because I want a separate light source for each compartment. The shelves will be placed side by side against a wall. Can a single power supply handle that, or would it be better to use a separate power supply for each shelf? What types of LED strips are available in terms of power and performance?Also: How should I run the cables? If I want to lead a cable up from the bottom to the switch, what’s the best way to do this without damaging the shelf?

For example, if each LED strip consumes about 5 watts, 10 strips would total approximately 50 watts. Therefore, power adapters rated around 60 watts are recommended to allow some margin.
For cable installation, I suggest using flat cable ducts or clips that you can discreetly mount on the back or sides of the shelf. IKEA Billy shelves usually have some tolerance around the grooves and drill holes, which allows you to run cables along them. This keeps things tidy and protects against mechanical stress. Plan the cable routes in advance and avoid sharp bends.
