FAQs

A1: What is the maximum total length of extension cords that can be connected?
Q1: It is recommended that the total length of all extension cords connected to a single power supply should not exceed 36 ft (about 11 m) to ensure stable signal and power supply. Exceeding this length may result in reduced brightness or unstable signal at the end of the light string.

A2: Will using multiple extension cords affect the brightness or effects of the lights?
Q2: Excessive extension cord length may cause voltage drop, affecting the brightness and stability of end LEDs. Choose lengths wisely based on installation needs.

A3: How do I correctly connect the extension cord with the light string or controller?
Q3: Align the arrow marks on the connectors, insert fully, and then tighten the waterproof nut clockwise.

A4: Can I connect several extension cords in series?
Q4: Yes, you can, but the total length should not exceed the recommended maximum, or the signal may weaken and some LEDs may not light up.

A5: Can the extension cord be used with T-splitter?
Q5: Yes. For multi-branch installations, use T-splitter with extension cords to ensure stable power and signal for each branch.

A6: Are the extension cords waterproof and suitable for outdoor use?
Q6: Extension cords are designed with IP67 waterproof rating and are suitable for permanent outdoor use. Always tighten the waterproof nut on connectors to prevent water ingress.

A7: What should I do if the extension cord becomes loose or has poor contact?
Q7: Check if the connectors are properly aligned and fully tightened. If needed, unplug and reconnect, ensuring there is no debris and contact is secure.
