What's in the Box
- 2 x Joomer LED String Lights (16FT, 50 LEDs each)
- 2 x Battery Boxes
- 1 x User Manual
Setup Instructions
- Battery Installation: Each battery box requires 3 AAA batteries (not included). Slide open the battery compartment cover, insert the batteries according to the polarity markings (+/-), and securely close the cover.
- Placement: Position the LED fairy lights in your desired indoor or outdoor location. The flexible silver wire allows for easy shaping around furniture, plants, windows, or other decorative elements.
- Optional Cutting: The light strands are cuttable. If a shorter length is desired, trim the wire only from the end opposite the battery box. Cutting from the front (near the battery box) may compromise functionality.

Operating Instructions

- ON: Slide the switch to the 'ON' position to keep the lights continuously illuminated.
- OFF: Slide the switch to the 'OFF' position to turn the lights off.
- TIMER: Slide the switch to the 'TIMER' position to activate the automatic timer function. The lights will remain in steady-on mode for 6 hours, then automatically turn off for 18 hours. This cycle will repeat daily as long as the batteries have power.
