Ikea Besta wall cabinet lighting installation tips

Hello everyone,

I have 2 Ikea Besta wall cabinets (60x64x20) hanging directly next to each other on the wall. So in total, they are 120 cm wide.
Each cabinet has 1 glass shelf and glass doors in front.

Now I would like to illuminate the cabinets. For example, the Omlopp spot would come into consideration. You could install 1 spot on the top inside each cabinet under the upper case panel.
However, my cabinets are hanging on the wall with a wall rail.
When I look at the mounting instructions of the SPOT, I don’t quite understand it.
You drill a hole through the back panel, then mount the SPOT. But right behind the hole is the wall rail (??). Even if the wall rail wasn’t there, I could lead the cable through the hole into the hollow space between the back panel and the wall where the cabinets hang. But how do I then get the cable out to connect it to the transformer? The cabinet lies flush all around on the wall. Or is the cable seriously supposed to be squeezed between the wall and the cabinet carcass?

Somehow, I don’t understand something. Alternatively, I could use Philips HUE for lighting, but the exact same cable routing problem arises here. It makes no difference whether I use lighting from IKEA or another manufacturer; the problem remains the same.

Hello,

I have neither Besta nor Omlopp, but I see two possibilities:
1. The rail has a cutout in the middle - could you pull the cable through there (and then possibly lead it out sideways from the rail)?
2. Use a hole saw and install the spot - the cable can then be led out upwards.

But with a hole saw, I won't get a proper hole in this Besta-paper construction. Everything will just crumble out. And if I mill from bottom to top, everything will probably break off messily and extensively at the top. Then wiping it with a damp cloth will probably be out of the question in the future.

The top layer of Besta is, as far as I know, hardboard. You can quite easily cut it with a hole saw. You could initially just cut a suitable hole in the inside of the top panel and then saw the outside from above (hole saws have a centering drill bit in the middle).

In theory, you could also just saw a hole from the inside and install the spot (and then you would only have a small hole on the top for the cable). Depending on the heat development of the spot, however, that could literally be fire hazardous - but exact information would have to be provided with the spot.

Ok, thank you very much for the answers! Then I will abandon the idea of lighting my Besta furniture again. That doesn't really make any sense and the information from IKEA is unfortunately more than sparse.

Hello, you could also mill a small groove into the corpus edge.
