Photoleaf Light is made of two visual parts
1. Leaves
2. transparent tube

The leaves part is made of biodegradable plastic known as biopolymer.
that contains.
1. photovolatic cell throughout the leaves
2. Energy efficient LED light
3.Light sensor that helps to lights up automatically when gets dark
4. rechargeble battery
Photo-volatic cells are inserted on the top of the leaves, they are enough to recharge the internal battery.
The concept is inspired by the fact of photosynthesis occur in the plants, in presence of light. Similarly photoleaf light request the owner to take it to the bright area to get recharge. And in the dark it liteup automatically for more than 5 hours.

The leaves part is just press fit to the polycarbonate/glass tube. To turn of the light, slightly rotate leaves to left.
