Wardrobe shutters with integrated LED edge-lighting: the RCP coordination architects miss in a Koramangala walk-in

A master bedroom in a Koramangala HSR-adjacent project, 3,200 sq ft, spec'd a floor-to-ceiling lacquered glass wardrobe with integrated LED strips running the full perimeter of the shutter frame. The architect's RCP showed the electrical outlet 1.2 m from the wardrobe datum—a standard placement that made sense until the shop drawing went up, and the site team realised the power feed would run directly behind the hinge jamb, making the LED transformer inaccessible after installation. This is the coordination gap that separates a commissioned atelier piece from a retrofit headache.

Why LED edge-lighting demands a separate electrical protocol

Integrated LED strips in wardrobe shutters—whether they run the top frame edge, the bottom plinth, or both—require a dedicated 12V DC transformer and a 230V AC feed. The transformer itself is typically 180 mm × 120 mm × 65 mm, and it must sit in a location that allows for maintenance, replacement, and thermal clearance. Standard residential electrical design does not account for this; the architect's RCP assumes outlets are for general convenience, not for a permanent, built-in lighting element.

In the Koramangala project, the original electrical spec placed the outlet at 1.2 m height, 300 mm to the right of the wardrobe's right-hand hinge jamb. The LED feed was to run horizontally through the frame cavity—a 40 mm aluminium extrusion that houses the strip itself. Once the shutter was hung, the transformer would be trapped behind the hinge, accessible only by removing the door or cutting into the wall. The site architect caught this at the shop-drawing stage, but only because the atelier's detail drawing explicitly marked the transformer zone and flagged the conflict in red.

The transformer footprint and clearance rule

LED transformers for wardrobe lighting run 12V, 60W to 120W depending on strip length. A 120W unit requires 50 mm of clear air on all sides for thermal dissipation. The transformer cannot sit inside the wardrobe cavity—it will overheat in the enclosed volume. It must mount on the wall, either recessed into a service cavity or surface-mounted behind a trim. In the Koramangala job, the team opted for a recessed mount: a 200 mm × 150 mm service box was cut into the wall, 50 mm behind the wardrobe's rear face, with the transformer mounted vertically inside. The 230V feed came from a dedicated 2A circuit breaker, run through a conduit that entered the box from above, then exited through a flexible whip to the shutter frame.

Shop drawing: the electrical markup that prevents site conflict

The atelier's shop drawing for a LED-integrated wardrobe must include four distinct views: plan (showing transformer location, conduit route, and shutter hinge geometry), section (showing frame depth, LED strip position, and transformer box recess), elevation (showing the shutter face and the electrical entry point), and a detail of the frame-to-transformer connection. This is not optional markup; it is the document that allows the site electrician and the carpenter to work in sequence without collision.

In the Koramangala case, the shop drawing revealed that the electrical outlet needed to move 600 mm to the left, to a location 1.8 m from the wardrobe datum, where it would feed a conduit run that climbed the adjacent wall and entered the service box from above. The architect amended the RCP, the electrician re-roughed the circuit, and the atelier supplied a pre-fabricated conduit whip that terminated in a quick-disconnect coupling inside the service box. This meant the shutter could be hung, tested, and removed for any future maintenance without breaking the electrical circuit.

Tolerance and the frame-to-conduit joint

The joint between the aluminium frame extrusion and the flexible conduit must hold a tolerance of ±2 mm. The frame is 40 mm deep; the conduit is 16 mm OD. If the conduit entry point is not precisely marked on the shop drawing—both the height and the lateral offset from the hinge—the site team will improvise, drilling a hole that may pinch the wire or create a stress point. In the Koramangala project, the entry point was marked as 35 mm down from the top of the frame and 12 mm from the frame's outer edge. This was dimensioned on the drawing and called out in the site handover notes. The carpenter drilled to these measurements; the conduit slid in with no rework.

Lacquered glass and moisture: why the transformer cannot be inside the wardrobe

Bangalore's monsoon humidity—June through September, with relative humidity often above 85%—creates condensation inside enclosed wardrobe cavities. Hard water from the Cauvery supply (TDS typically 200–300 ppm) deposits mineral residue on glass and metal surfaces. If the LED transformer sits inside the wardrobe, it will accumulate condensation and mineral dust, shortening its lifespan and risking electrical failure. The transformer must be mounted on the exterior wall, in a ventilated service box, where it can breathe and where it is accessible for cleaning or replacement without disturbing the wardrobe itself.

The Koramangala wardrobe shutters were lacquered in a soft-grey finish—a pattern we often specify for HSR and Koramangala master bedrooms because it reads neutral against both warm and cool wall tones. The LED strips (3000K, 90 CRI) were mounted in the top frame edge, creating a subtle downlight across the shelving. The shutter face itself does not need ventilation; the transformer box, recessed behind, does. This separation of concerns—light emission inside the frame, power management outside—is the fundamental principle that allows LED-integrated wardrobes to function reliably in Bangalore's climate.

The coordination checklist: what the architect must specify before the atelier begins

Before a wardrobe with integrated LED edge-lighting can be shop-drawn, the architect must provide the atelier with five pieces of information:

1. The exact location of the electrical outlet (distance from the wardrobe datum, height above finished floor, and which wall it is on).
2. The circuit capacity (whether the outlet is on a dedicated 2A circuit or shared with other loads).
3. Whether the transformer will be recessed or surface-mounted, and if recessed, the depth of the available cavity.
4. The LED strip specification (colour temperature, CRI, length, and whether top edge, bottom edge, or both).
5. The shutter hinge type and the door swing direction (to ensure the conduit route does not interfere with the hinge jamb).

In the Koramangala project, the architect provided all five. The site electrician and the atelier's site team worked from a single marked-up RCP, and the installation was completed without rework. If any one of these five items had been missing or ambiguous, the coordination would have stalled at the rough-in stage.

The handover document

Once the wardrobe is installed and the LED system is tested, the atelier delivers a handover document that includes the transformer's serial number, the circuit breaker rating, the LED strip specifications, and the location of the service box. This document should be filed with the project's electrical one-line diagram and the RCP. It is not a warranty certificate; it is a maintenance record. If the LED strips need replacement in two years, or the transformer fails, the site team can access this information and order the exact replacement without guessing at specifications.

Patterns and LED integration: which designs work best

Not all wardrobe patterns are equally suited to LED edge-lighting. Patterns with dense graphic elements—such as Deco Noir or Bronze Lattice—can create visual noise when backlit by an edge strip. The light reads as a halo rather than an accent. Patterns with open space and a clear visual hierarchy—such as Azure Blossom or Golden Geometry—allow the LED strip to frame the design without competing with it.

In the Koramangala wardrobe, the shutters were specified in a plain soft-grey lacquer, not a patterned glass. This allowed the LED strip to function as a pure lighting element, illuminating the interior shelving without any visual distraction. If the architect had chosen a patterned design, the atelier would have recommended a lower colour temperature (2700K instead of 3000K) to soften the visual weight of the backlit pattern.

Questions we get asked

Can the LED transformer be mounted inside the wardrobe if we add ventilation?

No. Ventilation holes in a wardrobe cavity do not provide sufficient air circulation to protect a transformer from condensation and mineral dust accumulation. The transformer must be mounted on the exterior wall, in a dedicated service box, where it can be cleaned and accessed without disturbing the wardrobe. This is not a matter of preference; it is a requirement for reliable operation in Bangalore's climate.

What happens if the electrical outlet is in the wrong location and we discover it after the wardrobe is installed?

The shutter can be removed and the conduit route can be re-run, but this requires breaking the electrical circuit and re-terminating the quick-disconnect coupling. It is disruptive and costly. This is why the electrical coordination must be locked in at the RCP stage, before the atelier begins the shop drawing. If you are uncertain about outlet placement, have the electrician mark the location on site before the wardrobe is ordered.

Can we use a wireless LED system instead of a hard-wired transformer?

Wireless (battery-powered) LED strips are available, but they require regular battery replacement and do not provide the consistent brightness of a hard-wired system. For a permanent, built-in wardrobe installation, hard-wired 12V DC is the professional standard. The transformer investment is modest—typically 3,500 to 5,500 rupees—and the system will operate reliably for 10+ years with minimal maintenance.

Does the LED strip thickness affect the frame design?

Yes. Most LED strips are 8–10 mm wide and 3–4 mm thick. The frame extrusion must be deep enough to house the strip, the diffuser, and the mounting bracket. A 40 mm frame depth is standard; anything less than 35 mm will require a custom extrusion, which increases lead time and cost. Confirm the frame depth with the atelier before you finalise the wardrobe specification.

What is the warranty on the LED strips and transformer?

LED strips typically carry a 3-year warranty against defects in manufacturing. Transformers carry a 2-year warranty. The atelier will supply replacement strips and transformers at cost if they fail within warranty. Beyond warranty, replacements are available as spare parts. The handover document will include the part numbers and the supplier contact information.

Commissioning a wardrobe with integrated LED edge-lighting

Talk to the atelier about your electrical rough-in and your wardrobe design. Bring the RCP, the electrical single-line diagram, and a clear photograph of the wall where the wardrobe will sit. We will mark up the electrical coordination on a shop drawing, flag any conflicts, and specify the transformer location and the conduit route. The atelier has fitted LED-integrated wardrobes in HSR, Koramangala, Indiranagar, and across Bangalore's residential micromarkets since 2008. We work to the millimetre and we document every coordination decision so that your site team can install without guesswork.
