1. low-consume efficient : based on the advanced soft-switch technology (Zero-Voltage-Transition / Zero-Current-Transition PWM Converter), a novel design realized with no radiator
2. uninterruptible light supply : with backup battery, the design works fine at fieldwork, and brings bright when power failured.
3. adjustable : only single illuminating system is needed, adjusting illumination according to the requirement, and trade-off can be sleect between brightness and batt
ery-time
4. novel single key control mode : only one normal bell button is needed to adjusting the illumination, simplified the installation, and easy to add the wireless switc

technical target
1. power supply voltage : 12v to 48v
2. delivered power: 0 to 70w
3. working mode : H-bridge PWM, completely separated ; 25 kHz to 250 kHz
4. energy efficient : 95%
5. battery solution: lead-acid battery, nickel-cadmium battery works fine; lithium battery is NOT suggested for security consideration but can be used.
