Key benefits Automatic dusktodawn control: the sensitive photocell turns lights on at low light and off at daylight, eliminating the need for manual switching. Energy and maintenance savings: prevents lights from running during daytime, reducing energy use and extending lamp life. Flexible installation options: supports DC 12V and AC mains (110V / 220V) systems so it fits a wide range of LED lighting and other circuits. Weather resistant for outdoor use: waterproof construction allows reliable operation in exposed environments. What this device does This is an automatic photo switch (photocell) designed to detect ambient light and switch LED or other lighting loads on and off accordingly. It delivers reliable, sensitive on/off switching without timers or manual control, making it ideal for street lights, garden or security lighting, signs, and other outdoor fixtures. Key features and specifications Function: Auto photo switch (photocell) for on/off control based on ambient light Voltage compatibility: DC 12V, AC 110V, AC 220V (select the correct model for your system) Current rating: 10 A maximum switching capacity Sensitivity: Designed to respond to changes in ambient light for dependable dusktodawn operation Environment: Waterproof construction for outdoor use Typical applications: Street LED lights, garden and pathway lighting, outdoor signage, security lighting Why customers choose this sensor Multivoltage support allows one sensor family to be used across lowvoltage DC installations and standard AC mains installations, reducing the need to source different parts. 10A switching capacity supports most LED fixtures and small lighting circuits. Waterproof design gives confidence for outdoor mounting where exposure to moisture is a concern. Simple, automatic operation removes the need for daily manual switching or complex control systems. Use cases 1) Street and pathway lighting: Install the photocell on polemounted LED street lights so fixtures automatically turn on at dusk and off at dawn, conserving energy and reducing maintenance calls. 2) Garden, driveway, and security lighting: Use the sensor with DC 12V landscape LED systems or ACpowered security lights to ensure consistent night illumination without manual intervention. 3) Outdoor signage and display lighting: Protect signs and illuminated displays from unnecessary daytime operation by adding automatic ambientlight control. Compatibility and selection tips Confirm the correct voltage version (DC 12V, AC 110V, or AC 220V) before installation to match your existing power supply. Ensure the lighting load does not exceed the 10A maximum switching capacity. Designed for outdoor installations; choose a suitable mounting location where the photocell can monitor ambient light without obstruction or direct exposure to artificial light that could affect operation. Performance and reliability Sensitive light detection provides consistent dusktodawn switching. Waterproof construction supports reliable outdoor performance and longer service life in wet environments. 10A capacity covers a wide range of LED fixtures and small lighting circuits for practical, everyday use. Contents and ordering Photocell automatic photo switch (select voltage variant: DC 12V, AC 110V, or AC 220V) Verify model and voltage when ordering to ensure compatibility with your lighting system. Safety notes Install according to local electrical codes and practices. Confirm power is isolated before connecting or disconnecting the sensor. Match the sensor voltage and current rating to your load and supply to avoid damage. This photocell offers a straightforward, reliable solution for automatic outdoor lighting control across DC and AC systems, with waterproof design and a 10A switching capability for broad applicability.
