ᐅ How can I safely and easily install lighting in Billy bookcases?

Hello everyone, I want to retrofit lighting in my Billy shelves and am looking for a simple but, above all, safe solution. It’s not just about the appearance for me, but also ensuring that the electrical installation is properly and safely done. I have seen that many LED light strips or individual spotlights can be installed, but I wonder which power supply and wiring options are recommended to avoid risks and keep everything as straightforward as possible.

Are there specific products or methods that have proven reliable? For example, how can power be routed cleanly and safely to the shelf without visible cables and without the risk of a short circuit?

I am also interested in the best way to mount the lighting so that it doesn’t look unattractive or damage the shelves. I look forward to your experiences and tips!

Hello,

In general, retrofitting lighting in Billy shelves is quite doable and doesn’t have to be complicated. It is important to choose LED lighting that operates with a low-voltage power supply, such as 12 volts or 24 volts DC. This voltage is much safer than 230 volts and reduces the risk of short circuits.

You can route the cables either through the back panel of the shelf (drill carefully and use cable grommets) or along the outside, depending on how much you care about a neat appearance. Many use self-adhesive LED strips with compatible connectors, which makes it easy to replace them later.

For power supply, it is recommended to use power adapters with overload protection that are designed specifically for LEDs. Make sure the power supply is not placed inside the shelf but plugged into a nearby electrical outlet.

For mounting, you can use the self-adhesive LED strips or small LED spotlights with clamp or screw brackets if you want a bit more flexibility.

If you like, I can provide some specific product examples.

I agree with that and would even say that a little LED magic for the Billy bookshelf isn’t difficult at all! 😊

I used LED strips with a slim power supply and stuck them under the shelves – you can hardly see anything from the outside, and the energy consumption is very low. Plus, the heat generation is minimal, making it practically perfect for wooden furniture.

If you want to add a bit of atmosphere:
With RGB strips, you can even change colors – whether you want it cozy or practical.

So go for it, it’s easier than it sounds! 😉

That sounds good, thanks. What exactly should I consider when drilling into the back panel? I don’t want to lose any load-bearing capacity if I, for example, make small holes for cable pass-throughs.

Also, I’m wondering what the best way to mount the power supply is. Can it be hidden inside the shelf, or is it better to place it completely outside, for example next to the power outlet?

And do you have any recommendations on how to integrate the switch effectively? I imagine it’s not that straightforward since shelves usually don’t have openings for switches.

Good approach to retrofit lighting in Billy shelves!

Regarding drilling: The back panel of the Billy shelf is often made of thin fiberboard or MDF material, which is not load-bearing—the shelf is supported by the side panels and shelves. Therefore, you can drill small holes (e.g., 10-12 mm (0.4-0.5 inches)) for cable routing without significantly affecting stability. It is important to make the holes clean and deburred to avoid damaging any cables.

Regarding the power supply: Ideally, the power supply should be placed outside the shelf to prevent heat buildup and to simplify maintenance. If you still want a solution inside the shelf, a well-ventilated area with plenty of distance from the wood is recommended.

There are several options for the switch:
1) A built-in rocker switch installed in a small cutout in the side or back panel (provided you rout the wood accordingly).
2) An inline switch on the power cable (usually inexpensive and easy to integrate).
3) Remote-controlled solutions (e.g., infrared or radio frequency) if you prefer to avoid running cables.

For mounting the LED strips, I recommend cleaning the adhesive surfaces with an alcohol pad before sticking them on. Additionally, you can secure cables with clips or small cable ties to keep them hidden.

Ah yes, that little pro tip! You wouldn’t believe how strong the bond is when you prepare the surface properly. I’m also a fan of neatly hiding cables; otherwise, it quickly becomes messy.

Regarding the switch: I’ve hidden small magnetic reed switches that close the circuit when you open a little flap – absolutely brilliant if you want it to be invisible. But you need to be up for a bit of DIY work 😉
