RBT – Regulated Burning Time
Regulated Burning Time
Applicable to LED heads. It allows a slow reduction of the light intensity towards the end of the burn time of the light. This feature is most popular for the use in caves as it allows the diver to have a residual light, albeit of lesser intensity, providing an operating margin of safety.
This is made possible thanks to the linearity of LED Drivers, for which the trend of its light output over time will be at its maximum value of brightness for 75% of the battery life, while in the remaining time there will be a gradual reduction of light intensity due to the reduction of the absorption of the LED head.
