Many of the public office are paying high on electric bills because of numerous outdoor public lighting installed in their area of responsibility. Today, with the presence of the Flow, a sustainable bamboo public lighting, electric bills of our government offices will definitely be lowered drastically. Since made of bamboo, the Flow is a self-maintaining public lighting system. It has the ability to operate using the principle of a vertical wind turbine. Another eco-factor for this lighting system is its possibility to disintegrate with nature. While the LED, wires, and dynamo are recyclable on the other hand and is a very favorable act to our environment.
