Quick Summary
These btfarm battery operated fairy lights are a 3M string with 30 warm white LEDs. They run on 3AA batteries, so they can be used where there is no power outlet, and they offer two lighting modes: Steady on and Twinkle.
The lights also include a timer function with 6 hours auto on and 18 hours auto off. That makes them easier to leave in place for regular decorative use, including indoor settings such as bedrooms, jars, gifts and photo frames.
Who It Is Best For
These lights suit buyers looking for battery powered decoration for indoor spaces, or for use where a mains outlet is not available. They also suit simple display decorating where a warm white string light and timer function are useful.
