These Multifunction String Lights are a versatile light set which is suitable for use indoors and outdoors in many settings.They feature 200 multi-coloured LED lights with 8 pre-programmed lighting sequences that are selectable via a button on the transformer/plug. Switching the lights on triggers an operating cycle with 8 hours on and 16 hours off allowing the lights to automatically come on at the same time each day, whilst remembering the chosen sequence. Select between Combined, Waves, Sequential, Slow-Glow, Chasing, Slow-Fade, Twinkle, or Static modes. These lights have the added bonus of a memory function, to remember the mode and setting between power cycles so there is no need to re-choose your favourite setting when powering on each day.The long-life energy efficient warm white LEDs are fitted with concave heads for consistent and uniform brightness at all angles and with a discreet green cable blend seamlessly into the green foliage of a Christmas tree.The lights are constructed from a corrosion-resistant copper wire core, which means they will last year-after-year. The total length of the fairy lights is 23.92-metres. The lit length of the string lights measures 15.9m with an 8-metre lead length from the plug to the first light.
