Foot-Candles by Application: Recommended Light Levels
Foot-candles measure how much light actually lands on a surface, and getting them right is the difference between a space that works and one that is too dim or wastefully bright. This guide gives target ranges by application.
A foot-candle is one lumen per square foot. Different tasks need different levels: rough storage might need 20, while detailed inspection or color matching can need 75 to 100+.
Target Ranges by Space
| Application | Typical Target (foot-candles) |
|---|---|
| Warehouse storage / aisles | 20 to 30 |
| Manufacturing, general | 30 to 50 |
| Auto repair / service bays | 50 to 75 |
| Detailed assembly / inspection | 75 to 100+ |
| Paint matching / color-critical | 100+ |
| Office / general | 30 to 50 |
| Gym / sports | 50 to 75+ |
These are general targets. Local codes, insurer requirements, and task specifics can change them, so treat them as a starting point.
Foot-Candles vs Lumens
Lumens describe total light a fixture emits; foot-candles describe what reaches the work surface after distance and spacing. To turn one into the other for your room, see the lumens vs watts guide and use the fixture calculator.
Applying It
Pick your target, then choose fixtures and spacing to hit it. The application guides, like the warehouse, auto body, and gym guides, recommend fixtures that reach these levels.
