Suitable for both indoor and outdoor use, its IP44 rating means that it can be used in the rain and all weather conditions. Each bulb draws a very low voltage and is placed 90cm equally apart from each other throughout its 23m length for an even distribution of illumination and brightness. Not least, the each bulb has a 20,000 hours lifespan so that you can get to use the string lights for quite a while.
