How to save on electricity bills for lighting your houses?

I found this very useful link that tells you how to save the cost on lighting your house. 

The strategies are quite simple and easy to do at home.
1. Change all your incandescent lamps to FLs or CFLs. if you are ready to spend some more money then you can use occupancy sensors.
2. Make use of maximum daylight by installing french windows (long). Try using full transparent glass panes with tint to avoid excess sun exposure, if any.
3. Avoid using thick curtains in rooms where daylight is limited.
4. Use light wall colors/wall papers which will increase the reflectance.
