This is how light bulbs work - an electric current heats the lamp filament to around 3,000 degrees, and it glows white-hot.The surface of the Sun is around 5,600 degrees, and it gives off a great deal of light.]]> 2017-02-27 19:05:51 UTC https://padlet.com/salazlor000/8nkogu7nt923/wish/156529081 salazlor000 https://padlet.com/salazlor000/8nkogu7nt923/wish/156529978 too much light can damage the retina in your eye. this can happen when you look at something very bright,such as the sun. altough the damage can heal. if its too bad it'll be permanent
