Millionsun integrated solar street light include high lumen LED lamp, LiFePO4 lithium battery, high efficiency sunpower microcrystal solar panel and a smart controller with PIR motion sensor. Generally, it outputs light in energy-saving mode; when the PIR motion sensor detects a moving object, it will automately light at full brightness for a certain time, then turn back to energy-saving mode. As there is no cable needed (no need to connect to municipal electronic power), it is simply installed and there is nearly no need for maintenance. Last but not least, it is 100% clean, green, renewable light, and can be used in for street, garden, country yard, parking lot,seaside resort and exterior area lighting wherever there is sufficient sunlight. Features: Solar panel, battery controller and LED lamp are integrated in one box, smart figure, rational structure, easy installation. Optimum system design, scientific and specific, to ensure the operating stability and reliability. High price-performance ratio. PIR Intelligent sensor and control management, advanced technology, simple maintenance. High luminous efficiency, long life-span, Eco-friendly. Easy to maintain and replacement.
