What is the approximate brightness of incendiary flares?

• A. 50 candela
• B. 70 candela
• C. 90 candela
• D. 100 candela

Answer: (B)

The approximate brightness of incendiary flares is indeed around 70 candela, which makes it a suitable choice for ensuring visibility in emergency situations. Candela is a unit of measurement that indicates the intensity of light emitted in a particular direction. In the context of incendiary flares, which are used to signal distress or for illumination in low-light conditions, a brightness level of 70 candela is effective for being seen from a significant distance, necessary for safety in emergency operations.

This level of brightness provides sufficient illumination to alert other vehicles or personnel while promoting safety during rescue or response operations without being overly blinding. Understanding this measurement allows responders to evaluate the effectiveness of various light sources they may encounter or utilize during emergency situations.
