What Is a Lighting Requirement?
Lighting requirement refers to the amount of brightness needed to properly illuminate a room or workspace. The correct lighting level improves visibility, comfort, productivity, and energy efficiency.
Different rooms require different lighting intensities. For example, kitchens and offices typically need brighter illumination than bedrooms or living rooms.
How Lighting Requirement Is Calculated
The lighting requirement is commonly estimated using the room area and the recommended lumens per square foot.
Formula
Total Lumens = Room Area × Recommended Lumens Per Square Foot
This estimator uses standard lighting recommendations for common room types to provide an approximate lumen requirement.
Recommended Lighting Levels by Room Type
| Room Type | Recommended Lumens per sq ft |
|---|---|
| Bedroom | 20 |
| Living Room | 30 |
| Kitchen | 40 |
| Office | 50 |
| Garage / Workshop | 60 |

Frequently Asked Questions
How many lumens do I need per square foot?
Most residential rooms require between 20 and 40 lumens per square foot, while offices and workshops may need 50 to 60 lumens.
How many LED bulbs do I need?
Divide the required lumens by the lumen output of your bulb. For example, a 10W LED bulb typically produces around 800 lumens.
Is brighter lighting always better?
Not always. Excessively bright lighting can create glare and discomfort. The ideal brightness depends on the room purpose.
