Lighting the staircase vertically from the ceiling
It casts the person's body shadow on the treads, which causes tripping and a lack of safety.

Common mistakeAiming light at glass and mirrors
“Got a spotlight hitting the windows at night? You're blinding your guests!”
- The problem
- Aiming lights at reflective surfaces such as glass creates distracting glare that blocks the view outside.
- Technical explanation
- Light should be aimed at walkways and opaque walls. Avoid aiming lights at windows at night entirely, so you can enjoy the view of the garden.
- The result
- A comfortable evening sitting and a clear view of the villa's garden without distraction.
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.
Common mistakeRandomly placed bollard lights
“Has your garden turned into an airport runway because of your path lights?”
- The problem
- Placing bollard lights too close together, randomly and excessively
- Technical explanation
- The ideal path bollard is spaced every 4 to 5 metres, and its height should ideally be half the width of the area being lit
- The result
- Elegant, calm garden paths with no extra fixture costs
Common mistakeLighting glass windows
“Have lights aimed at your living room windows? You've just blinded your guests!”
- The problem
- Aiming light at glass makes it act like a mirror, reflecting harsh light into the eyes and blocking the view of the garden.
- Technical explanation
- Light should be directed at walkways and solid walls (Wall Washer), completely avoiding reflective surfaces.
- The result
- A comfortable living room at night with a clear view of the garden.
Common mistakeChoosing the wrong wattage for façades
“Want your villa façade to stand out from afar? Don't fit it with a 5 W light!”
- The problem
- Using very weak Grazer fittings for tall façades.
- Technical explanation
- A tall façade needs a 36 W fitting (about 2300 lm) to reach the top of the building, while 5 W (300 lm) is left for soft lighting of lower walkways.
- The result
- A palace façade that catches the eye of the whole neighbourhood.
Common mistakeThe one-metre, two-metre rule (grid layout)
“A spotlight every 2 metres? That rule will make your villa look like a supermarket!”
- The problem
- Spacing lights evenly (in a grid) wastes electricity and leaves the ceiling full of holes that are tiring to look at.
- Technical explanation
- Real lighting design is based on “task distribution”: lighting only the furniture, corridors and artwork, and leaving restful areas (shadows) to create contrast.
- The result
- A cleaner ceiling with 40% fewer openings, savings on the electricity bill, and twice the sense of luxury.
Common mistakeThe wrong staircase lighting
“You installed powerful spotlights above the stairs, and the result... a dark, dangerous staircase!”
- The problem
- Using wide-angle ceiling spotlights for an open staircase, so the light scatters before it reaches the steps.
- Technical explanation
- Stairs need either very narrow-beam ceiling spots so the light reaches the floor, or better still, low-level wall lights that illuminate the treads directly.
- The result
- Safety for your family going up and down, and an elegant, hotel-like staircase.
Common mistakeMiscalculating downlight spacing (d=h)
“Why are there dark patches between every light in your home's corridors? Because the contractor doesn't know this rule!”
- The problem
- Spacing downlights too far apart and at random.
- Technical explanation
- The engineering rule for uniformity is (d = h): the distance between the centres of two fittings should equal the fitting's height above the working surface.
- The result
- A softly and evenly lit corridor that feels more spacious and luxurious.
Guide values; the final decision rests with a qualified engineer under the applicable code.
