Hi. I visited your web site today. It's great! I have an assignment on the tungsten light bulb. And I need some information about the light bulb.(like what's inside the bulb; How to improve the light bulb etc.) If you do not mind, would you please send me E-mail. This is my E-mail address: chunan_cao@hotmail.com Have a good day Chunan ______________________________________________________ Get Your Private, Free Email at http://www.hotmail.com
