From Death Note, Light's last name is Yagami. Light Yagami
In the live action version they basically took the idea of Death Note and made their own story with it. It's not meant to follow the real story.
Ryuk kills Light by writing his name in the Death Note.
he dies at the very end of the second movie. he wrote his own name in the note book to keep other light from killing him. he pretends to die in front of light then light says " I've won." then light goes crazy and riuk kills him with the death note. then so manydays later L dies.
He went to the Shinigami world after Light told him to get rid of the death note, but he returned after Light memory's back
In the Death Note: How to Read, it says that he weighs 119 lbs

you get a Light wig, buy his Death Note online, and wear cloths that looks like his. but i dont understand why you wanna be Light. L is way more awesomer.
