We have inherited a lot of energy saving lights in our house. Would it be dreadful of me to change most of them back to halogen? They make our kitchen feel cheap and grey and I am happier to sit in near darkness rather than turn them on when guests are here. But I know our bills will go up and it's not great for the planet. I just want to have nice lighting at home!! Any idea on the impact of changing around 24 lights over?
