EcoFactor: Lighting that banks on renewable energy

These unique flowers with exceptionally simple functions are lovely by day and dazzling at night. The solar cells gather power during the day and charge the high power LED during night, making them gorgeously twinkle in random patterns in the dark. These lights make an excellent lighting option for streetlights or garden paths because of their low power consumption. The design supports an eco-friendly environment as they are energy-efficient and low-maintenance, making Sunflowers an excellent choice for our streets.

The Dark Side:

Usually street lights are known to suck up a tremendous power. These lights on the other hand save energy and reduce pollution, what flaw could I find in such a product?
