A compact controller board designed for 1.2V Ni‑MH solar lawn lights, lanterns and road lamp modules. This circuit module connects the solar panel, battery and LED lamp to provide reliable control of charging and lamp operation in home and landscape solar lighting systems. Key benefits Designed for 1.2V Ni‑MH battery systems: matches common rechargeable cells used in small solar lawn lights and lanterns. Restores or upgrades solar lights: replaces a failed controller board to a light to service without replacing the entire fixture. Simplifies system control: centralizes charge/discharge and lamp switching functions on a small, dedicated PCB for dependable daily operation. Saves maintenance time and cost: or retrofit existing landscape and road lamp units rather than buying fixtures. What it does (functionality) Interfaces between the solar panel, 1.2V Ni‑MH battery and the lamp load to manage charging and lamp control. Provides automated control logic appropriate for solar landscape lighting setups, enabling daylight charging and nighttime lamp operation when installed in compatible fixtures. Protects and manages the battery and lamp circuit as part of a complete solar lighting module. Key attributes Compatibility: specifically for systems using a 1.2V Ni‑MH rechargeable cell and typical solar lawn/landscape lamp wiring. Form factor: compact circuit board suitable for installation inside small lantern housings or lamp modules. Construction: printed circuit board with standard electronic components for solar lighting control. Performance: optimized for smallscale solar landscape and road lamp applications where a 1.2V nickel‑metal hydride cell is used. Typical applications a damaged controller board in home solar lawn lights to restore dusktodawn operation and battery charging. Retrofit or build DIY solar landscape lanterns and pathway lights using a 1.2V Ni‑MH cell and a small solar panel. or maintain small road lamp or garden lighting modules where the original control electronics have failed. Installation and compatibility notes Intended for use only with 1.2V Ni‑MH rechargeable cells and compatible solar panel/LED lamp configurations. Verify wiring and voltage compatibility before installation. Compact PCB design fits inside most small lantern and landscape lamp housings; ensure connections are secure and protected from moisture and corrosion. Use with fixtures designed for 1.2V Ni‑MH systems to maintain safe and reliable operation. Why choose this board Straightforward replacement or upgrade option for solar landscape lighting systems that use 1.2V Ni‑MH batteries. Focused design for common home and garden solar lamp applications, helping extend the life of existing fixtures and reduce replacement costs.
