Introduction: Malaysian Living Rooms & the Plaster Ceiling Trend
In Malaysia, plaster ceilings have become a popular choice for homeowners aiming to achieve a modern, clean look. Combined with LED downlights, they provide both aesthetic appeal and energy efficiency.
But one of the biggest questions homeowners ask is: "How many downlights do I actually need for my living room?" Over-lighting makes a room harsh and increases electricity bills, while under-lighting makes the space feel dull.
This guide simplifies everything you need to know about plaster ceiling lighting, helping you plan your living room setup perfectly.
Quick Answer: Downlight Calculation Formula
To calculate the number of downlights:
Room Area (sqm) x 200 lumens ÷ Lumen output per light
For example:
Living room: 5m x 4m = 20 sqm
Recommended: 20 sqm x 200 = 4,000 lumens needed
Using 10W LED (450 lumens each): 9 downlights needed
Factors That Affect the Number of Downlights
Room Size & Shape – Larger or irregular-shaped rooms need more lighting points
Ceiling Height – Higher ceilings may require brighter or more lights
Wall Colours – Darker paint absorbs light, needing more output
Furniture Layout – Areas with reading or feature spaces need task lighting
Common Downlight Layouts for Living Rooms
Even Grid Layout – Balanced light distribution
Perimeter Layout – Lights focused along walls or curtain areas
Zoned Layout – Light for seating, feature walls, and walkways
Pro Tip: Keep a 1.2m to 1.5m gap between downlights for even distribution.
