These intelligent solar lights will automatically adjust their own brightness dependent on how much sunshine they are getting. In long summer months they will light for around 8 hours per night at full 20 lumen brightness. As the days get shorter, they will adjust how bright they shine, so they will still try to light for around 6-8 hours albeit at less brightness. Regular solar lights just light at full brightness until their battery runs down, which in winter months could be just an hour or two. Please note, they do still need sunshine to recharge, but on non sunny days they will still out perform regular solar lights. Each of the 8 warm white filament style bulbs are topped with a \'fisherman\' style lantern shade with a large 14cm diameter. Each of the lanterns are spaced 50cm apart giving an overall lit length of 3.5M, and there is a generous 2 metres of thick black cable from the solar panel to the start of the first lantern.
