This product has 3 different ways for solar light to operate based on your individual needs. The solar panel has been updated to a laminate version which is more efficient at converting the sunlight into battery changing power. It also has a life expectancy 3 times longer than the original epoxy board design. The 60 LED is now bigger than before and it is far brighter than other similar lights on the market. Despite being brighter the lamp duration has been increased by more than 2 hours due to the battery capacity being increased to 2200mAh. As this solar light is designed to be used outdoors, it may be exposed to rain. To improve the product life, there are now 2 separate seals between the internals and the back case. Therefore the light is more durable and weatherproof than ever before. The PIR motion sensor has been updated so that it can detect people 8-10m.
