3 Inch vs 4 Inch LED Downlight — Which Size Do You Need? (Pakistan Guide)
The most common question when buying LED downlights in Pakistan is simple: should I get the 3-inch or the 4-inch? The size refers to the diameter of the hole in your false ceiling that the downlight fits into. Getting this right matters — the wrong size means either an ill-fitting light or a hole too large to cover.
Quick Answer
3-inch (75mm hole): Best for bedrooms, corridors, smaller rooms. The most common size in Pakistani homes.
4-inch (95-100mm hole): Best for drawing rooms, large lounges, open-plan spaces where you need higher lumen output per fitting.

Room-by-Room Size Recommendation
Bedroom (100-200 sq ft): 3-inch, 12W Globe. Use 2-3 lights. Pack of 6 (Rs.1,890) covers 2 bedrooms.
Drawing room (250-400 sq ft): 4-inch, 18W Globe for high ceilings (2.7m+). Or 6 x 12W 3-inch for a refined, evenly lit look.
Corridor (long, narrow): 3-inch, 7W. Space every 1.2-1.5 metres.
Kitchen: 4-inch or Frameless Panel. Either a 4-inch 18W Globe or 24W Frameless Panel provides the task lighting needed.
Bathroom: 3-inch, 7W or 12W. A single 3-inch is usually sufficient.
What If I Already Have Holes?
Measure the hole diameter. 75mm = 3-inch. 95-100mm = 4-inch. If your existing holes are a non-standard size, Deltalite's Frameless Adjustable downlights fit holes from 50mm to 115mm (2 to 4.5 inches) — see Frameless Panel Lights.
