Where the strip sits in the shelf section, and how the emitter stays hidden
Three positions work. The strip drops into a shallow groove machined in the underside, sits flat behind the front edge, or lives inside the hollow body firing down through a slot. Setback hides the emitter, and the sightline that decides how much you need runs from the lowest seat in the room.
Output belongs in the low to medium range. One option where the planks are short and the lengths awkward is the EnoLED 24V MaxCut series, with its cut behavior, watts per foot and color temperatures taken from the product page. A strip firing from inside a closed body generates heat whenever it runs, and that cavity has no airflow. A channel from the sections that fit inside a shelf body helps dissipate it. It is never mandatory, and it reduces but does not guarantee that dots disappear. Density of the diodes, depth of the profile and the diffuser chosen decide the rest.
Routing power into a shelf that has no carcass
Decide the route now and drill it later, with the plank off the wall on a bench. The cable can follow the bracket pin hole or pass through the wall face behind the body.
The detail that saves a rebuild is the angle: drill that pass-through oversize and sloped toward the back so the cable turns in without a kink you can never reach again. Low voltage cable buried in a finished wall is still a code matter, so the route and any penetration get confirmed with the licensed electrician.
Cut points, connectors and the end of a run
Many strips can be cut at designated points and reconnected with compatible connectors or by soldering, depending on the product, and both need confirming for that exact tape before you mark a length.
The join you conceal best is the one you never make inside the shelf. A solderless strip-to-wire connector with a 72 inch lead carries the connection down to the driver, provided the lead length and fit suit your tape as published.
A driver location with air around it and a way back in
With every installed length fixed, size the supply: published watts per foot times each shelf's footage, added together, plus at least 20 percent current headroom before you pick a supply with the rated output to match. Verify both. Read the voltage off each box: a 24V plank run needs a supply marked 24V and, where one is fitted, a control marked the same.
Give the driver air and a way back in. A base cabinet, a closet behind the wall, or a joinery void with a removable panel works; fixed drywall does not.
Prep, dry fit and mounting, in that order
Work on a bench with the planks down. Drill the pass-through, degrease the mounting face, and let it dry. How an adhesive behaves depends on that tape and that substrate, so follow the instructions supplied with the product; where the face is raw or oiled, let a screw fixed channel carry the strip. See how a surface gets prepped for the cleaning sequence and why adhesive lets go for the causes.
Dry fit before anything is stuck down. Lay the strip loose, hold the plank at its finished height, and look at the light. Only then does anything go on for good.
