Darker rooms are better for children since their eyes are less stimulated. Try to wean children off night lights by gradual reductions in their brightness. Better sleep will also often be obtained by relaxing before bedtime. A story in bed is a good idea, especially if you read slower and slower as the book progresses. Children who require naps should be able to enjoy them but don't let them run on so long that the bedtime routine is put off. Stick to the same bedtime wherever possible. Block out sunlight from children's bedroom windows, too, so they are not awakened too early.
