It works with a wide range of low-voltage lighting setups including solar-powered lights and LED strips.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can I choose whether the light turns on during the day or at night?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! The switch offers two selectable working modes. In Night Mode, the light activates automatically when it gets dark and turns off at dawn. In Day Mode, the light turns on during daylight hours and switches off at night. You can configure the mode to suit your specific lighting needs.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the purpose of the 30-second sensing delay?\u003c\/h4\u003e\n\u003cp\u003eA: The built-in 30-second default delay prevents the switch from triggering due to brief or temporary changes in light levels — such as a car's headlights or a passing cloud — ensuring stable, reliable operation and avoiding unnecessary on\/off cycling.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the maximum load current this switch can handle?\u003c\/h4\u003e\n\u003cp\u003eA: The switch is rated for a maximum of 5A. However, for optimal performance and safety, it is recommended to keep the load current at or below 4A when operating at 12V, and at or below 2A when operating at 24V.\u003c\/p\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e{\"@context\": \"https:\/\/schema.org\", \"@type\": \"FAQPage\", \"mainEntity\": [{\"@type\": \"Question\", \"name\": \"What voltage systems is this light sensor switch compatible with?\", \"acceptedAnswer\": {\"@type\": \"Answer\", \"text\": \"This automatic light sensor switch supports DC voltages from 3.7V up to 24V, making it compatible with 3.7V, 5V, 12V, and 24V DC systems.
