What Is Recessed Lighting?
Recessed lighting, also known as can lights or downlights, is installed into the ceiling, providing a clean and unobtrusive lighting solution. These lights are popular in kitchens, living rooms, offices, and commercial spaces due to their modern look and versatility.
Why Use Recessed Lighting?
- Aesthetic Appeal: Provides a sleek, modern design without visible fixtures.
- Space-Saving: Ideal for rooms with low ceilings or minimal wall space.
- Customizable: Available in different sizes, brightness levels, and color temperatures.
- Energy Efficiency: Many recessed lights use LED bulbs, which consume less energy and last longer.
How to Calculate the Number of Recessed Lights You Need
The number of recessed lights required depends on room size, ceiling height, and the type of lighting you need. Our Recessed Lighting Calculator simplifies this process using the following formula:
Recessed Lighting Calculator Total Lumens Required = Room Area (sq ft) × Lumens per Square Foot
Recommended Lumens per Square Foot for Recessed Lighting Calculator
| Room Type | Recommended Lumens per Sq Ft |
|---|---|
| General Lighting | 20 lumens/sq ft |
| Task Lighting (Kitchen, Office) | 35-50 lumens/sq ft |
| Accent Lighting | 10-15 lumens/sq ft |
| Bathroom Lighting | 40 lumens/sq ft |
Once you calculate the total lumens required, divide it by the lumens per bulb to get the total number of recessed lights needed.
Example Calculation
- Room Size: 12 ft × 10 ft = 120 sq ft
- Lighting Type: General Lighting (20 lumens per sq ft)
- Total Lumens Required: 120 × 20 = 2,400 lumens
- Bulb Type: LED (800 lumens per bulb)
- Number of Lights Needed: 2,400 ÷ 800 = 3 lights (rounded up)
Recessed Lighting Spacing Guide
Proper spacing ensures even light distribution and prevents dark spots. Use the Ceiling Height Rule:
Spacing Between Lights = Ceiling Height × 0.5
| Ceiling Height | Recommended Spacing |
| 8 ft | 4 ft apart |
| 9 ft | 4.5 ft apart |
| 10 ft | 5 ft apart |
Best Practices for Recessed Lighting Placement
- Start 2-3 feet away from walls to prevent harsh shadows.
- Space lights evenly based on ceiling height.
- Use dimmers for adjustable brightness control.
- Avoid over-lighting, which can make a room too bright and harsh.

Common Questions About Recessed Lighting
1. How Many Recessed Lights Do I Need for My Room?
Use our formula: Total lumens required ÷ lumens per bulb to determine the number of lights.
2. What Is the Ideal Spacing for Recessed Lights?
Spacing should be half the ceiling height (e.g., 8 ft ceiling → 4 ft spacing).
3. Can I Install Recessed Lights in Any Room?
Yes, but different rooms require different brightness levels. Kitchens and offices need higher lumens, while living rooms can use softer lighting.
4. What Is the Best Bulb for Recessed Lighting?
LED bulbs are the most energy-efficient, providing bright, long-lasting light with low electricity costs.
