The Konstsmide set of 10 LED festoon lights have smoked acrylic globe bulb casings on a black PVC cable. This fabulous set not only adds a contemporary style to any space but is also highly practical with a dimmable function and with an IP44 rating, which makes them ideal for both indoor and outdoor parties, barbeques or for some external or internal decoration, simply plug-in and decorate! Please note the transformer is IP20 rated so must be connected to an indoor socket or in an outdoor weatherproof socket. The replaceable 1800K amber LED's are extremely energy efficient to use and a sustainable choice as they can be replaced individually rather than having to replace the whole set.Colour: SmokedMaterial: PlasticIP Rating: IP44Power Source: IP20 rated plug transformer.Dimmable: Dimmable with LED compatible dimmer switch.Light Output: 7W, AmberGuarantee: 2 years guarantee.Dimensions: Overall - L 4.5 Metre
