Solar Light Circuit Board Remote Controller for solar integrated street lamps and outdoor lighting modifications. Combines microwave motion detection, light control, and remoteadjustable brightness and timing for flexible, practical operation. Key features Reliable LED drive: LED voltage 2.8V to 3.3V at 2.2A for consistent illumination. Battery compatibility: Works with 3.2V LFP batteries and 3.7V lithium batteries for easy retrofits and replacements. Solar input limit: Accepts up to 40W from the solar panel. Detection technology: Microwave induction with light control and motion induction. Detection range: Effective induction distance of 5 to 10 meters. Induction timing: Triggered brightness lasts approximately 25 seconds, then switches to low brightness, long brightness, or off according to mode. Adjustable brightness and timing: Set illumination level and automatic timing with the included remote control for convenient operation. Remote power: Remote requires 2 AAA batteries, not included. Benefits Versatile retrofit solution for solar street lamps and integrated outdoor fixtures, compatible with common battery types. Motionactivated lighting improves responsiveness while reducing unnecessary fullbright operation. Remotecontrolled brightness and timing simplify setup and daily use without ladder access to fixtures. Clear technical limits and simple installation requirements make it practical for maintenance and modification projects. Typical applications Retrofit or control boards in solar integrated street lights and area luminaires. Yard, pathway, and driveway lighting where motionactivated and timed illumination are desired. Small parking lot or community lighting systems needing adjustable brightness and remote timing. Installation and use notes This control board does not include overcharge or overdischarge protection. Use only the specified compatible battery types and install according to the user manual. Do not exceed a 40W solar panel input. Observe correct battery polarity and wiring when connecting the battery and panel. Remote requires 2 AAA batteries, which are not supplied.
