The FREEDOM Plus series by Leadsun represents a highly efficient and cost-effective solution for outdoor solar street lighting, combining a robust LED luminaire, long-life LiFePO4 battery system, high-efficiency controller, and a durable aluminum alloy frame. This series is ideal for both new installations and the replacement or upgrading of existing solar street lights, offering long-term reliability, simplified installation, and low maintenance costs, all backed by Leadsun’s three-year warranty. Its thoughtful design and quality components ensure the system meets the demanding requirements of urban streets, industrial zones, and other outdoor environments.
The FREEDOM Plus series adopts a modular construction, with all major components rated to IP66 standards. Structural parts are made from high-tensile aluminum alloy, which provides superior corrosion resistance, heat dissipation, and waterproofing. This rational combination of material and design allows the fixtures to withstand harsh environmental conditions while preventing premature failure. The modular approach also enables flexible deployment and maintenance, ensuring the system remains secure and operational for extended periods.
One of the key advantages of the FREEDOM Plus series is its dual approach to deployment. For completely new installations, the luminaire can be directly connected to Leadsun’s high-efficiency monocrystalline solar panel. This allows for a quick, simple installation process while achieving excellent performance. For replacement or upgrading projects, the integrated battery system enables users to connect the FREEDOM Plus luminaire to existing solar panels, reusing original light poles and solar modules. This approach reduces material usage, minimizes installation costs, and allows existing infrastructure to remain in service, creating a practical and economical solution for upgrades.
At the core of the system is Leadsun’s intelligent steady-state controller, which ensures smart management of the lighting cycles and comprehensive protection of the entire system. The controller is equipped with a waterproof programming connector, charging port, and switch, allowing convenient access for future maintenance. It optimizes performance while protecting the battery and electronics, delivering consistent reliability in outdoor applications.
The FREEDOM Plus series is powered by environmentally friendly LiFePO4 batteries that contain no harmful metals. Leveraging Leadsun’s patented battery management technology, the system increases the depth of discharge from 60% to 90%, extending battery life beyond eight years. This robust battery system ensures stable, long-term energy storage, supporting continuous operation even in variable weather conditions.
The lighting system employs high-efficiency LED modules capable of achieving up to 180 lumens per watt at 25°C. The lenses are constructed from anti-ultraviolet polycarbonate, providing both anti-aging and impact-resistant properties for long-term usage. The cutoff lens design minimizes light pollution, ensuring the environmental footprint of the installation is reduced while maintaining uniform and wide coverage. Each luminaire is also compatible with PIR motion detection, allowing the lights to operate at full brightness when activity is detected and reduce to 30% brightness when the area is unoccupied. This adaptive operation extends battery autonomy while maintaining adequate lighting levels.
The FREEDOM Plus series is available in multiple models to suit different project needs. The UP20L model includes a 205Wh LiFePO4 battery, 16 LED chips, a 70W PV module, and a typical luminous flux of 3,800 lumens. The UPG40P model increases the battery capacity to 410Wh with 36 LED chips and a 100W solar module, achieving 7,200 lumens. The UPG60R model features a 615Wh battery, 36 LED chips, a 150W solar module, and delivers 9,900 lumens. All models operate with PIR motion detection, support T2 or T3 optional light distribution, and are compatible with multiple color temperatures (3,000K, 4,000K, 5,000K).
Installation recommendations vary by model, with mounting heights ranging from 4 to 12 meters and installation distances between 15 and 45 meters. Each fixture is designed to withstand wind speeds of up to 130 mph, with EPA and APA values optimized for mechanical stability. The recommended arm diameter for mounting is 60 mm across all models. Packaging dimensions and weights are optimized for shipping and handling, making the FREEDOM Plus series not only a high-performance lighting solution but also a practical choice for streamlined deployment.
Overall, the FREEDOM Plus series combines modular construction, intelligent control, robust batteries, high-efficiency LEDs, and durable materials to deliver a reliable, cost-effective, and environmentally responsible solar street lighting solution. Its versatility, long life span, and ease of installation make it a practical option for urban, industrial, and rural outdoor lighting projects.
