ᐅ Ikea Metod: How can I optimize the lighting inside tall cabinets using LEDs?

Thank you for the detailed answers so far! To add some information: My tall cabinets are 60 cm deep (24 inches) and about 220 cm high (87 inches), divided into 4 levels. The power supply is a standard 230V line nearby, but I want to step it down to 12V. Due to space constraints, the LED strips and their power supplies should be installed as unobtrusively as possible. A smart Wi-Fi control is important to me, but it needs to work reliably and preferably without much wiring effort. Do you have any recommendations for brands or specific components for power supplies, LEDs, and controllers that work well with Metod? Also, a tip on how to properly adhere the LED strips so they don’t come loose over time would be helpful.

This provides enough space for multiple light sources per level. For bonding, I recommend, in addition to the usual LED strip tape (usually 3M), an extra fixation with transparent, heat-resistant silicone adhesive, which spreads easily but holds firmly without leaving residues. This prevents late detachment caused by temperature changes or cabinet movements.

A smart control via Wi-Fi is important to me, but it must work reliably and preferably without much wiring effort.

Here I suggest Wi-Fi controlled 12V LED controllers that can be operated via an app and communicate directly with your router over Wi-Fi (not ZigBee). It is important to choose stable controllers with good support and regular firmware updates. Brands like Giderwell or Milight offer such devices, which you connect to 12V power supplies. Make sure to protect the power supply to avoid voltage fluctuations.

Do you already have a clear idea whether you want to link all LEDs into one group, or control different zones independently?

This is a very useful tip that I have applied myself in several kitchen installations. It ensures that the LEDs never come loose, even under mildly heat-intensive conditions.

How did you handle this with your Metod tall cabinets? Are there any proven products or installation tips that work particularly well?

Another practical tip: LED strips can be neatly installed in aluminum U- or L-profiles designed specifically for LED tapes. These can often be cut precisely to size and mounted, which helps with alignment. For control, I have had good experience with products from Shelly in smart home systems. They are Wi-Fi based, reliable, and have a stable app. You can also integrate them directly into Metod drawers or doors if you are reasonably handy.
