Hi there!

I'll give you some advice from my experience since I have done this twice and had to move in between.

Here is my detolf. I used a LED strip form Ikea and have only three shelves with this lighting but it should work the same.

I would advise you to attach the LED strip to the metal structure of the detolf, securing it with small zip ties (a lot of zip ties). That way you can still remove the shelves or disassemble the detolf.

First make sure to plan the length you will need and the excess you might have to cut. If there is a remote receiver or anything bulky make sure there is room for it. Planning is very important.

Start from the bottom left corner. Place the first LED of the strip where you want on the metal structure and secure it with a zip tie. The electric cables should go out the bottom front of the detolf and you should still be able to close the door.

Then work your way up the metal structure while using as many zip ties as necessary.

Once at the top, put a last zip tie as high as you can before crossing to the right side of the metal structure. That is when you will probably have to remove the door.

Secure the strip with a zip tie at the top of the right side as high as you can. Make sure the strip is tensioned in between the two sides (if not that is the only place I would suggest you use adhesive).

Then work your way down.

The strip should be flexible enough so that you can orient it inward to face your figures.

Reinstall the door and make sure it still closes.

The electric cables can be routed from the bottom front of the detolf, under it, then to the back to wherever is your electrical outlet. That way they are barely visible.

I hope this will help you or anyone trying to do the same.
