home lighting

Sometimes I think we really need to replace our home lighting. It's not bad, but it's getting old, and some of the chandeliers are really showing their age. Plus, we have at least a couple of lighting globes that have broken and shattered, and we've never been able to match the globes so we never replaced them. Replacing the lighting would be a big job and might even cost a lot of money, but I wonder if it would really improve the lighting of our home.
