Hello everyone,

I want to retrofit my Billy shelf with lighting and have two main questions: First, which type of cable is best suited for power supply, especially if the goal is to keep it as discreet as possible – should I use thin stranded wires or something more robust? Second, I’m interested in how you most elegantly attach the light strips or lamps to the shelf without damaging the surface, while ensuring neat cable management.

I’ve already considered LED light strips, but I’m unsure about the best way to route the cables as unobtrusively and securely as possible, avoiding cable damage or a flimsy installation. Additionally, there’s the question of how to mechanically fix everything, since I want to alter the shelf as little as possible.

Looking forward to your experiences and tips!

Hello Youssefga,

Great idea to enhance the Billy shelf with lighting! 😎

Regarding the cable: I prefer flexible stranded wire; it’s thin, easy to hide, and sturdy enough if you install it properly – just place it along the back panel or behind the shelves. For attaching the LED strips, double-sided adhesive tapes designed specifically for LEDs work really well—they hold firmly and don’t require drilling. If you want an even neater look, I’d suggest using cable channels in the color of the shelf—you can cut them to size and mount them on the sides. That makes everything look very tidy.

Oh, and one more tip: always lay the cables loosely and avoid bending them sharply; otherwise, you might get flickering lights later on. Good luck! 😊

I recommend 2-core stranded cables with 0.75 mm² (0.0012 in²) cross-section for the power supply.

For mounting: self-adhesive LED tracks or clips that can be screwed or glued.

Place the cable behind the shelf and secure it with clips if necessary.

I find it interesting that the discussion mainly focuses on tape and clips without questioning their long-term durability. Just a brief point: How reliable are these adhesive tapes really, especially when humidity or temperature changes?

Couldn’t this adhesion weaken quickly with somewhat heavier light strips or frequent use? In my experience, screws or at least sturdy clips with anchors provide a more secure solution, even though drilling into the material is required. Here, one should carefully weigh the compromise between appearance and safety.

I agree with Josefane. Why is adhesive tape always seen as the cure-all?

Sticking is only a temporary solution. If you really want to enhance the Billy shelf and not just light it up temporarily, you should also be willing to ensure proper fixing.

You can use small, discreet screws that are hardly noticeable and last forever. Appearance without substance doesn’t help in the long run.

For a clean retrofit of lighting in the Billy shelf unit, the following approach is recommended:

1. Cable: Use flexible two-core stranded cables with a cross-section of at least 0.75 mm² (0.75 mm²). These are sufficiently rated for standard LED strips and offer flexibility during installation.

2. Mounting: Special LED aluminum channels with clips are ideal. These can be attached to the shelf using small screws. If drilling is not preferred, high-quality double-sided adhesive tapes are an alternative, although their durability depends on weather conditions and adhesion quality.

3. Cable routing: To prevent cable damage, cables should not be bent sharply but installed with a minimum bending radius. Route the cable along edges or within color-matched cable ducts.

4. Safety: Always ensure that the power source is safely accessible and that all connections are properly insulated by a qualified person.

This procedure ensures a durable, safe, and aesthetically pleasing retrofit.
