  • DC24V voltage input, safe and reliable, wide range of application.
  • High-power constant-current drive ensures the brightness consistency of LED and the evenness of light box.
  • OSRAM SMD3535 3V 5W high-power LED, good heat dissipation, large current, high reliability.
  • Adopt 2.0mm thick and high heat conduction aluminum substrate for heat dissipation, provide reliable heat dissipation for the light source, and improve the service life of the product.
  • Using 10X30° optical lens, the light is scattered from two directions to ensure the evenness of the light source and no macular spots.
  • Patch terminal connection for easy installation and maintenance.
  • The single lamp is 4.5w, ensuring the high brightness in the large light box and the striking distance up to 5m.

Setup Warning

  1. the mainline of the power supply shall use a cable above 2×1.5mm squared. If the power line of the straight lamp needs to be extended, it shall choose a wire of the specification above 1.5mm squared /16# to avoid excessive heating of the power line caused by overload and adverse consequences. The length of the power line between the switching power supply and the straight lamp shall not exceed 3 meters, otherwise the line loss will increase and the total power will increase.
  2. please use the wiring scheme in the connection diagram, with a maximum cascade of 20PCS, which requires power connection from end to end. There are several ways of power supply output and several ways of power supply to the light bar, so as to prevent overload of single power supply output and damage of power supply.
  3. when installing the straight lamp, screw the screw into the hole of the fixing frame and lock it tightly. After lighting for a long time, do not suspend the installation;
  4. when there is a bare conductor at the end of the straight lamp, first peel the wire about 10mm with diagonal pliers and screw it into the wiring head for insulation protection.
  5. to ensure waterproof and anticorrosive, after the power cord is screwed into the terminal head, it is recommended to inject the terminal head with single-component silica gel (or neutral glass glue or waterproof grease) to protect the exposed copper wire covering the power cord;
  6. do not live touch or live operation of this product;
  7. it is recommended to use the switch power (with short-circuit protection, overvoltage protection and overcurrent protection) with 80% power.
