Common mistake

Marble spoiled by LED dots

Reviewed under Eng. Abdullah Al Balushi

“Installed concealed lighting under a marble shelf and it shows as dots? You've ruined the luxury!”

The problem

The dots of the LED strip reflect on glossy surfaces.

Technical explanation

Glossy surfaces need a continuous dot-free strip, or an “aluminium profile” with a diffuser cover that hides the dots completely.

The result

Kitchen and Majlis details as perfect as in hotels.

“You made luxurious marble shelves, and the strip's reflection shows up as dots? There goes the luxury!”

The problem
Installing a standard LED strip above glossy surfaces (marble or mirrors), which reflects the LED dots and looks cheap.

Common mistakeLighting windows and mirrors

“Lighting your mirrors and windows to make your home look luxurious? You're blinding yourself!”

The problem
Aiming lights directly at glass and mirrors bounces the light back as very uncomfortable glare.
Technical explanation
Glass doesn't reflect light softly like painted walls do, so lighting should be from the side or hidden behind the mirror (Backlit) to avoid discomfort.
The result
Hotel-style bathrooms and corridors, without visual discomfort.

Technical explanation

The result
A home garden that looks like a luxury resort

“Can't decide between warm yellow or natural white for your project?”

Choosing a gloomy colour for the façade or a harsh colour for bedrooms.

Common mistakeOverdoing cove lighting

“Not every wall in your home deserves indirect cove lighting!”

The problem
Overusing cove lighting in small rooms creates visual noise and eye fatigue.
Technical explanation
Too much light creates “light noise”; small rooms need just two well-planned light points to achieve balance.
The result
Savings on the gypsum and lighting budget, plus greater peace of mind.

Common mistakeChoking the cove lighting (the bottleneck)

“Installed cove lighting but the light is weak and muffled? The problem is the gypsum dimensions, not the lamp!”

The problem
Leaving too small an opening in the gypsum cove, which traps the light inside.
Technical explanation
The light outlet (the horizontal edge) should be larger than the vertical edge, and no less than 15 cm, so the light spreads smoothly across the ceiling.
The result
A wide spread of light that makes the room feel larger, instead of a narrow, distracting line.

Common mistakeThe hidden 220V hazard

“Planning cove lighting somewhere within reach of your hand? Never buy 220V!”

The problem
Using cheap 220V (High voltage) strip in TV shelving or bedrooms where it can be touched.
Technical explanation
220V strips are meant for high ceilings, with runs of up to 50 m, but they are not shock-safe. For shelving, use 24V, which is completely safe.
The result
Complete protection for children and your family against any electrical short circuit.

Common mistakeThe wrong distance for a 24V driver

“You installed a great 24V strip, but the light fades towards the end? The mistake is the driver!”

The problem
Placing the driver (transformer) too far from the cove strip, causing voltage drop and weaker light.
Technical explanation
The driver should be close to the strip (no more than 3 m away), and if the run is longer than 5 m, it should be split into separate circuits.
The result
Cove lighting with even brightness from one end of the room to the other, with no fading.
