Core Performance Advantages
High Brightness Modular LED Light Source
Equipped with multi-group independent high-brightness SMD LED bead modules, each panel packed with dozens of high-lumen LED chips, supporting customizable power tiers from 60W to 180W by adding/removing light modules flexibly.
Adopts high-transmittance PC optical mask lens with uniform light diffusion design, eliminating dark zones, glare and light spot deviation; light output uniformity reaches above 0.7, offering wide-angle flood lighting covering broader road surface without wasted luminous flux.
High luminous efficiency up to 180lm/W, far exceeding conventional solar street lights, converting electrical energy into visible light with minimal heat loss to maximize night illumination brightness.
Pure white neutral 6500K color temperature reproduces clear object visibility, ideal for traffic roads, parking areas and public walkways to enhance nighttime safety.
High-Efficiency Monocrystalline Silicon Solar Panel System
Large-size integrated monocrystalline silicon solar panel with surface anti-reflection coating, photoelectric conversion efficiency hits 23%, 30% higher than polycrystalline counterparts.
Rapid charging performance: under standard 1000W/m² sunlight irradiation, the battery pack can reach full charge within 6–8 hours on sunny days; works normally under weak cloudy/overcast light with low-light absorption technology.
Sealed lamination panel structure resists surface oxidation, dust accumulation and rain erosion, maintaining stable charging efficiency throughout its service cycle without obvious attenuation.
The panel and lamp body are integrated as one piece, no separate wiring required, greatly simplifying installation and avoiding extra cable aging failure risks.
Intelligent Energy Storage & Control System
Built-in large-capacity LiFePO4 lithium battery pack, featuring stable discharge platform, strong low-temperature resistance, and no risk of thermal runaway compared to ternary lithium cells.
Intelligent MPPT charge-discharge controller embedded inside, automatically adjusting charging current to prevent overcharge, over-discharge, short-circuit and reverse connection damage; supports auto dusk-to-dawn sensor control, human motion sensor optional for further power saving.
Full charged battery can sustain continuous lighting for 12–18 hours at medium brightness; low-battery protection function reserves 20% residual power to avoid deep discharge damage extending battery cycle life.
Intelligent power adjustment mode: dim light output during midnight low-traffic periods to cut energy consumption, extending daily working duration without compromising basic lighting safety.
Dual-Mode Adjustable Universal Mount Bracket
Innovative dual-installation interface bracket design, supporting two installation methods: vertical pole mounting on street light poles and wall-mounted installation on building facades, compatible with pole diameters from 40mm to 60mm.
Multi-direction angle adjustable structure allows 0–90° vertical tilt and horizontal rotation adjustment, freely calibrating solar panel facing angle for maximum sunlight capture and adjusting light projection angle to match different road width requirements.
Thickened die-cast aluminum alloy bracket with anti-rust matte black coating, fastened by stainless steel anti-loosening bolts, resisting wind vibration loosening in open outdoor environments.
Quick disassembly assembly design without complicated tools, one-person installation finished within 10 minutes, cutting labor and construction costs for bulk engineering orders.
Service Lifespan & Attenuation Loss Control
LED Light Module Lifespan & Light Attenuation
The high-quality SMD LED chips boast a rated service life of 50,000 hours under standard working conditions; with integrated aluminum heat sink behind each light panel for rapid heat dissipation to lower chip operating temperature.
Strict light attenuation control: only 3% luminous flux loss after the first 1,000 hours of operation; total attenuation below 20% after 30,000 working hours, far outperforming ordinary low-cost solar lamps with fast brightness degradation.
Detachable independent LED modules enable single-panel replacement instead of full lamp replacement when individual sections fail, drastically reducing post-maintenance cost and component waste.
Solar Panel Service Life & Charging Attenuation
Monocrystalline silicon solar panel offers a 25-year linear power output warranty; annual charging efficiency attenuation controlled under 0.7%, only 17.5% total power loss after 25 years of outdoor exposure.
Tempered glass surface with anti-UV coating prevents yellowing and light transmittance drop caused by long-term ultraviolet radiation, ensuring consistent sunlight absorption capacity year after year.
Lithium Iron Phosphate Battery Cycle Lifespan
Built-in LiFePO4 battery supports over 3000 complete charge-discharge cycles, equivalent to 8–10 years of daily use in regular solar lighting scenarios.
Built-in battery management system (BMS) balances cell voltage evenly to avoid single-cell over-discharge aging; low self-discharge rate below 3% per month during long idle periods, suitable for seasonal low-usage regions.
Overall Lamp Body Structural Service Life
Full lamp housing made of die-cast aluminum alloy with electrostatic spray anti-corrosion coating, anti-rust, anti-oxidation and anti-aging; structural frame maintains stable mechanical performance for over 10 years without deformation or cracking.
All internal electronic components are isolated from external moisture and dust, effectively slowing down circuit aging and electrical loss, minimizing long-term failure rate of the whole lamp.
Industrial-Grade Protection Rating & All-Weather Durability
IP66 Overall Waterproof & Dustproof Grade
Complete lamp body passes IP66 professional waterproof and dustproof certification: fully sealed internal cavity structure blocks fine dust intrusion completely, and withstands powerful high-pressure water jet washing from all directions without water penetration inside the light source, battery and control circuit.
Multi-layer silicone rubber sealing gaskets installed at all splicing gaps between lamp housing, light module cover, solar panel and mounting base; anti-aging silicone material avoids sealing failure from temperature alternation.
Drainage channel reserved inside the lamp body to eliminate condensed water vapor generated by indoor and outdoor temperature difference, preventing circuit short-circuit caused by internal moisture accumulation.
Extreme Temperature Adaptability
Wide working temperature range: -40°C to +65°C, stably operating in severe cold northern winter and high-temperature tropical summer environments without shutdown or performance collapse.
Die-cast aluminum housing acts as passive heat sink to dissipate heat from LED chips and batteries under high-temperature sunlight exposure; low-temperature lithium cell formula guarantees normal charge and discharge efficiency in sub-zero freezing weather.
UV & Corrosion Resistance
Outer surface matte anti-UV paint coating resists long-term strong ultraviolet radiation, no paint peeling, fading or shell yellowing after years of outdoor open-air use.
Anti-salt spray corrosion performance reaches level 8, capable of stable service in coastal areas with high salt fog humidity, avoiding metal bracket and shell rust damage.
Wind Resistance Mechanical Performance
Integrated compact streamline lamp body design reduces wind resistance coefficient; matched with thickened fixed bracket and stainless steel locking bolts, it withstands level 12 strong winds without shaking, tilting or falling off mounting poles, meeting municipal road wind safety standards.
