When the standard lightbulb was invented, naturally, we applauded. But science means progress - and the world is now looking for alternative ways to light up our homes. This is one of the best we've found. Inside the Sun Jar is a highly efficient solar cell, a rechargeable battery and three low energy LED lamps.

When the jar is placed in direct sunlight, the solar cell creates an electrical current that charges the battery over a few hours. When it gets dark or lights are turned off, this energy powers the three natural-coloured LED lamps inside the jar. The frosted glass of the jar then diffuses the light, giving the appearance of trapped sunlight.
