| 1. | In radiometry, radiosity, luminance, luminous flux, luminous intensity, illuminance, luminous emittance ).
|
| 2. | The luminous intensity of a typical candle is approximately one candela.
|
| 3. | A typical candle produces very roughly one candela of luminous intensity.
|
| 4. | In research, Mueller measured luminous intensity and studied polarization of light.
|
| 5. | A common candle emits light with a luminous intensity of roughly one candela.
|
| 6. | The atmosphere on a clear day only reduces luminous intensity by about 30 %.
|
| 7. | Light with the same radiant intensity at other wavelengths has a lower luminous intensity.
|
| 8. | Such a source could then be used to calibrate instruments designed to measure luminous intensity.
|
| 9. | :There is no correlation between luminous intensity and efficiency.
|
| 10. | In either case, luminous intensity is tabulated from this data and used in lighting design.
