Strobe light can flash for how many hours when operated intermittently?

• A. 6 hours
• B. 12 hours
• C. 18 hours
• D. 24 hours

Answer: (C)

Endurance for a strobe when used intermittently depends on how much energy the battery can supply and how long the light is actually on versus off. Flashing with pauses between bursts saves power, so the device is rated for a longer total flashing time than it would run continuously. For this strobe, the manufacturer specifies about eighteen hours of operation under intermittent use. That means if you run it in a pattern of on moments and off periods, the total time it can flash before the battery is depleted is roughly eighteen hours. Continuous flashing would use energy more quickly, giving a shorter total time.
