"Light is the first of painters."

How the Recessed Light Calculator Works

Using 2025 global lighting standards, the recessed light calculator computes:

  • Optimal light count and spacing
  • Total lumens required
  • Beam overlap and coverage
  • Energy consumption (kWh)
  • Fixture and installation cost
  • CRI and color temperature
Lights = (Area × Lux) ÷ (Lumens × Utilization Factor)
Spacing = Ceiling Height × 1.5

Recommended Lighting Levels (2025)

Room Type Lux Lumens/sq ft Spacing
Kitchen 500–800 100 4–5 ft
Bathroom 400–700 80 4 ft
Office 300–500 70 6 ft
Bedroom 200–400 40 6–8 ft
