ReflectionClass changes name of class and causes fatal error

Getting some serious wierdness when using reflection to get a class instance. The code is so simple I really dont get where this is going wrong, it would seem that reflection is changing the class name. So:

$reflect = new ReflectionClass($class);
print_r($reflect);  
ReflectionClass Object
(
  [name] => Db_Table_Data_Binding
)

return $reflect->newInstance(); // fatal error class Db_Table_Binding Not Found 

even if I wrap it in a if statement to confirm:

if($class === "Db_Table_Data_Binding")
{
   return $reflect->newInstance(); // fatal error class Db_Table_Binding 
}

Cant really see whats going on here... Any help would be great.
