Editing Candela (section)

=== Examples ===
* A common candle emits light with roughly 1&nbsp;cd luminous intensity. 
* A 25&nbsp;W [[compact fluorescent light bulb]] puts out around 1700&nbsp;[[lumen (unit)|lumen]]s; if that light is radiated equally in all directions (i.e. over 4{{pi}} [[steradian]]s), it will have an intensity of <math>I_\text{V} = \frac{1700\ \text{lm}}{4 \pi\ \text{sr}} \approx 135\ \text{lm}/\text{sr} = 135\ \text{cd}.</math>
* Focused into a 20° beam (0.095 steradians), the same light bulb would have an intensity of around 18,000&nbsp;cd or 18 kcd within the beam.
