So, my tip is to simply turn off all lights. Sounds simple but there is a myth that fluorescent strip lights use heaps of energy to power up. The truth is they use about 5 seconds worth of the electricity used to run them to start them up. So as long as you're not turning them on an off every 5 seconds, it's worth turning them off. However the lamps (bulbs) are affected by continual switching on but not so much that it's anything to worry about.

Other things to consider regarding lighting is occupancy sensors, great to use in walk through areas and bathrooms, especially if you have kids who don't turn the lights off! These are becoming more and more widely used in domestic situations as well as Guest Houses and Hotels. Not only does it save you money but there's a bit of a wow factor too.
