Rainbow coloured LEDs are similar to traditional multicolour lights but the colours included are pink, violet, orange, & a softer blue, rather than the typical red, blue, green, this gives the lights a beautiful almost pastel effect, which is really eye catching. Being set onto a clear cable rather than the standard dark green, means you can incorporate them anywhere indoors or out, without a dark cable stealing the show! These lights also have a built-in timer, so once you switch them on they will stay lit for 8 hours, & turn off for 16 hours, before lighting again at the same time the next day, this means that you can simply set & forget & let the lights operate themselves. There are 8 various multi-action modes that include lively flashing options as well as softer or 'smooth' modes as well as the classic 'static' mode. 200 LEDs 16M Lit Length 8M Cable from transformer to start of the lights Suitable for outdoor (transformer must be plugged indoors) Built-in 8 hours on, 16 hours off Multi-action modes including ' Static'
