Lighting a large area with conventional lamps can be very costly to run in energy costs, in addition to installing the infrastructure and maintenance costs. However, with some careful planning, the use of green gadgets, such as solar powered LED bricks can be an attractive and practical technique for lighting pavements and other paved areas.
For the home, you can use solar bricks to light up your garden path, but as the photo above shows, it works perfectly well for any public area too. With many cities in the UK being regenerated, I encourage architects to use these energy saving bricks for lighting in public areas!
