ᐅ Are there affordable LED spotlights available for retrofitting old KALLAX units?

Hello everyone,

I am considering how to find an affordable solution to retrofit LED spotlights into my old IKEA KALLAX shelving unit. I want to improve the lighting of the shelf, especially in the lower section, without too much effort or high costs. I am mainly looking for inexpensive LED spotlights that are easy to install, possibly battery-powered or USB-operated, so I don’t have to carry out major electrical work. Has anyone had experience with such retrofit LED lights for KALLAX? Which models would you recommend, and what should I watch out for? Thanks for your tips!

Hey kajari51, that sounds like a great project! 🙂

For my KALLAX, I used these inexpensive, battery-powered LED panels that you can attach with adhesive strips. They’re often available for under 10 euros (about $11) at hardware stores or online. The lights are usually warm white and offer quite decent brightness for the price.

This is a great solution because you don’t have to do any wiring, and it’s very flexible! Just stick them to the underside of the shelves, and you’re done.

Give it a try, it’s really brilliant!!!

As an addition: When looking for affordable LED spotlights for KALLAX, you should especially consider the power supply and mounting method. Battery-operated spotlights are easy to install but usually don’t provide the most durable solution, as the batteries often need to be replaced.

A cost-effective alternative is USB LED spotlights with a plug-in power adapter, if there is a power outlet nearby. These provide continuous light and generally offer better brightness than battery-operated options.

Additionally, I recommend choosing LED spotlights with good ratings for color temperature (around 3000K for warm white) and brightness (at least 300 lumens) to ensure the lighting in the shelving unit is functional.

Only adhesive tape? That’s not really a stable solution, if you ask me. Those things end up falling off after a short time or hanging crooked.

Honestly: if you don’t do a bit of DIY and properly drill or screw them in, you won’t get decent lighting. Affordable is good, but cheap can become expensive if the spots keep falling down or don’t provide the light you want.

I would rather recommend something with clip or screw mounting, even if it takes a bit more effort.

Here is a short tutorial on how I installed my affordable LED spotlights for a KALLAX shelf:

1. Selection: LED spotlights with USB connection, approximately 5–7 watts power (around 400 lumens), warm white.
2. Installation: I mounted small angle brackets on the underside of the shelves and attached the spotlights to them.
3. Wiring: USB extension cable routed to a power outlet, since the shelf is placed close to a wall.
4. Cable management: Cables neatly secured to the back of the shelf with cable clips.

Common mistakes:
- Not securing strain relief on the cables → cables break
- Attaching spotlights only with adhesive tape → they fall off

Conclusion: With some effort, this solution is very stable and can be easily expanded or replaced if needed.

Battery LED spotlights on the KALLAX are fine for short-term lighting. For continuous use, it’s better to use USB or 12V with a power supply. Adhesive tape can be replaced with screws, if possible.
