1. The lamp has 64 long-life high-brightness LEDs as an illumination light. Controlled by Dislocation Circuit it can work in each of the following three ways: When 24 LEDs of them are used, the maximum lighting time is between 50-60 hours; When 40 LEDs of them are used, the maximum lighting time is between 40-50 hours; When 64 LEDs of them are used, the maximum lighting time is between 30-40 hours.
2. The lamp has a built in protective electricity circuit against overcharging and overdischarging.
3. The lamp has a built-in automatic emergency circuit. When it is in the state of charging, all the LEDs are off.
4.20 hours is needed when the electricity of the battery is full. The charging voltage must be AC220-230V 50Hz.
5. It has a built-in battery, rechargeable, free of maintenance, with the capacity of 4A, 6V.
When its electricity runs out, it requires a timely charging. If it is not used for a long time, it should be charged every three months with charging time not less than 20 hours, and it should be placed in dry place.
