Candela is the SI unit of luminous intensity. It measures the power emitted by a light source in a particular direction, considering the sensitivity of the human eye to different wavelengths. Historically, one candela was roughly equivalent to the light emitted by a standard candle. In practical terms, it represents the intensity of light emitted in a specific direction by a source of monochromatic light with a frequency of 540 terahertz. This measure is crucial in fields like lighting design and photometry, ensuring that spaces are lit appropriately for human use.
Definition of LumenLumen is the SI unit of luminous flux, representing the total quantity of visible light emitted by a source per unit of time. While candela focuses on the intensity of light in a particular direction, lumen quantifies the amount of light energy emitted in all directions. It provides a measure of the perceived power of light, which is essential for evaluating the efficiency and effectiveness of lighting devices. In essence, lumens help consumers understand the brightness of light bulbs, influencing energy consumption and lighting choices.
| Candela/square Meter (cd/m²) | Lumen/square Foot/steradian (lm/ft²/sr) |
|---|---|
| 0.01 cd/m² | 0.0929 lm/ft²/sr |
| 0.1 cd/m² | 0.929 lm/ft²/sr |
| 1 cd/m² | 9.29 lm/ft²/sr |
| 10 cd/m² | 92.9 lm/ft²/sr |
| 20 cd/m² | 185.8 lm/ft²/sr |
| 30 cd/m² | 278.7 lm/ft²/sr |
| 40 cd/m² | 371.6 lm/ft²/sr |
| 50 cd/m² | 464.5 lm/ft²/sr |
| 60 cd/m² | 557.4 lm/ft²/sr |
| 70 cd/m² | 650.3 lm/ft²/sr |
1 cd/m² = 9.29 lm/ft²/sr
1 lm/ft²/sr = 0.108 cd/m²
Example 1:
Convert 5 cd/m² to lm/ft²/sr:
5 cd/m² = 5 × 9.29 lm/ft²/sr = 46.45 lm/ft²/sr
Example 2:
Convert 3.5 cd/m² to lm/ft²/sr:
3.5 cd/m² = 3.5 × 9.29 lm/ft²/sr = 32.515 lm/ft²/sr
