1. Using the microcomputer intellective controller to transfer the light energy to electrical energy. East to install since no wriing&trenching, energy conservation and environmental.

2. The microcomputer intellective controller is composed by advanced special-purpose integrated circuit, high conversion efficiency, prevent over-load&over discharge. Output short circuit protection, extend work life, on the safe side, convenient usage.

3. High effective Non-maintaining accumulator cell, strong storage, durable usage.

4. Automatic track type time controller. Automatically adjust the working time along with different illumination time in various seasons. For extending the work time energy conservation intellective controller will automatic Shut-off the light at the deep-night.
