If you already have lamps then you can just change the lamp shades and this can affect the lighting. Lamp shades are a really cost effective way of doing things. Just keep it simple and experiment with different options.
If you are going out to buy new things then that is a lot more fun. Try to do a bit of research first to find out what styles you like and the types of prices that you will have to pay. This will put you in a much better position when it comes to negotiating.
Lamp shades are a great way of influencing light if you already have the right light fittings. You don't need to buy expensive lamp shades, just think about the likely effect on the room and make your decision from there.
