Blossoming Garden Solar Light

There are a great deal of garden lights to choose from if you’re searching for something to add to your plants. The Blossoming Garden Solar Light absorbs solar power like most outdoor lights, but it it uses up all of that power for more than the LED light. This motorized flower blooms every single morning and closes up at night.
There is a very small solar panel attached to the bottom of the stem. The panels charge up the rechargeable batteries. They then in turn power the LED light and flower petals that automatically open and close. The stem itself is metal with a bright bronze finish and the whole thing stands 16 and ½ inches tall.

First green LED means a lighting revolution is fast approaching

Scientists at the National Renewable Energy Laboratory (NREL) tried to apply their expertise in solar cell technology to build a green LED light from the ground up, they surprisingly centered the objective at their very first try. In doing so they solved a long-standing technological problem and paved the way for the large-scale employment of white LEDs for public and domestic illumination over the course of the next few years. LED lights are unanimously regarded as a vast improvement over previous light bulbs because of their much longer lifespan and higher efficiency, which ends up saving us money in the long run, even when the higher initial cost is taken into account.
Further predictions from the Department of Energy estimate that the move toward LEDs for both public and domestic lighting could save the U.S. as much as US$120 billion over the course of the next 20 years.
