If you thought about something related to weights the you guessed it right, this new innovation called Gravity Light uses weights to glow that means it doesn’t require kerosene or electricity to light up your home.
GravityLight consists of a weight bag and a holder which lights up the LED lamp when some weight usually around 20 pounds is put into the bag.they say that we require only 3 seconds to lift the weight and it keeps the LED light on for 30 Minutes.
