Lumen, a fundamental unit of luminous flux, measures the total quantity of visible light emitted by a source. Defined by the International System of Units (SI), one lumen represents the amount of light emitted in a unit solid angle of one steradian from a uniform source with an intensity of one candela. Lumen serves as a critical parameter in assessing the brightness and efficiency of lamps, LEDs, and other lighting devices. Its practical applications span across industries, ensuring optimal illumination in architectural design, photography, and various engineering fields.
Definition of Foot-lambertFoot-lambert, a non-SI unit of luminance, quantifies the brightness perceived from a surface reflecting or emitting light. Primarily used in the United States, one foot-lambert equals one lumen per square foot or approximately 3.426 candela per square meter. This unit is integral in evaluating screen brightness in cinemas, televisions, and projectors, ensuring images are displayed with optimal clarity and contrast. The foot-lambert's unique ability to relate light intensity to surface area makes it indispensable in industries focused on visual display and lighting quality control.
| Lumen/sq. Meter/steradian (lm/m²/sr) | Foot-lambert (fL) |
|---|---|
| 1 lm/m²/sr | 3.426 fL |
| 2 lm/m²/sr | 6.852 fL |
| 3 lm/m²/sr | 10.278 fL |
| 4 lm/m²/sr | 13.704 fL |
| 5 lm/m²/sr | 17.13 fL |
| 6 lm/m²/sr | 20.556 fL |
| 7 lm/m²/sr | 23.982 fL |
| 8 lm/m²/sr | 27.408 fL |
| 9 lm/m²/sr | 30.834 fL |
| 10 lm/m²/sr | 34.26 fL |
1 lm/m²/sr = 3.426 fL
1 fL = 0.292 lm/m²/sr
Example 1:
Convert 5 lm/m²/sr to fL:
5 lm/m²/sr = 5 × 3.426 fL = 17.13 fL
Example 2:
Convert 3.5 lm/m²/sr to fL:
3.5 lm/m²/sr = 3.5 × 3.426 fL = 11.991 fL
