are vampires ok in light like light from a lamp or something??

Yes. They would only sparkle in direct sunlight, artifical light does nothing to them.

it would make sense that they can because it's not natural light. And when they're in bella's room in the movie she has her lamp on and he didn't sparkle what-so-ever.

There are many different species of vampires and they all react differently that is why in vampires movies vampires react differently to certain things like sunlight .Yes all vampires are ok in lamp light and things of that matter.

yeah, well they don't sparkle if thats what you mean. it's only sunlight that they could expose themselves.

No they don't sparkle in light coming from a lamp, otherwise they wouldn't go to school, because the last tie i checked there is alot of lights at school. And in the movie he don't sparkle(sad but true)in the hallway, caferteria, and what not.=)

YES

yup they r not affected by candle light or edward would be glittering everywhere ....the book also says they glitter only in sunlight tht is y the cullens take holidays on sunny days
