How long must the lights of a FL-1D floodlight remain off before restarting?

The correct duration for how long the lights of a FL-1D floodlight must remain off before restarting is 10-15 minutes. This cooldown period is essential to prevent damage to the floodlight's internal components, particularly the bulbs and electrical systems.

During operation, floodlights generate significant heat. Allowing the lights to cool down for the specified time ensures that the components have enough time to reach a safe temperature before being turned on again. If the lights are restarted too soon, it can lead to overheating, reduced lifespan of the bulbs, and potential failure of the equipment.

By adhering to the 10-15 minute cooldown period, operators maintain the efficiency and longevity of the floodlight, ensuring safe and reliable operation in various conditions.
