The hidden box that still needs to be reached
You see the line of light under a shelf. You may never see the power supply that makes it work. That box is commonly called an LED driver, and it needs somewhere suitable to live before the shelf detail is finished.
If the light later stops working, the fitting is only one possible cause. Someone may need to inspect or replace the driver. Sealing it into joinery turns an ordinary maintenance task into a much bigger job.
Ask the team to show the driver location on the drawing, identify the light it serves and explain how it will be accessed. A removable panel is only useful if the equipment can actually pass through it. This small coordination decision belongs alongside the attractive lighting detail.
The driver needs a home of its own
Location affects maintenance and can affect cable design and performance. The electrician needs the actual equipment information, not a generic assumption about a “small transformer”.
Check the manufacturer’s requirements
Ask for a location that meets the selected driver’s ventilation, temperature, enclosure and access requirements. Cable lengths and the load also need to be assessed for that system.
I avoid universal clearance figures. They are not interchangeable across products or installations. Record the requirements with the specification.
Rehearse the replacement
Can the driver be reached, disconnected by the appropriate professional and replaced without damaging the finished room? Can someone identify which light it serves?
Before approving the joinery, ask to see the access route drawn as clearly as the light itself. Keep a photograph and a label identifying the driver and the light it serves. Retain the model and specification with the handover information. Years later, that record lets the person servicing it start with the correct equipment instead of opening cupboards to hunt for an unlabelled box.
