This pack of 4 Solalite LED outdoor solar garden deck lights takes all the hassle out of installing lights in your decking area.During the day, the solar panel converts the suns energy and stores it in the rechargeable battery. At night, the solar garden light turns on automatically using the stored solar energy cycling between red, green and blue to produce a stunning colourful display.They don\'t just have to be used for decking, they can also be used for path lighting or ground lights. Use several of them as unobtrusive flower bed lights, or line pathways with them to make your garden instantly feel more welcoming.Top-quality durable stainless steel construction allows lights to be walked on without damage occurring when installed on decking or paths.Solar lights dont require any wiring and are ready to install as soon as you\'ve found a space for them. As they are powered by the sun, they are environmentally friendly as well.Please note: Solar LED lighting is dependent on the amount of sunlight they get each day. The run time will be reduced during non-summer months as charge times are reduced by hours of daylight and light strength.
