The government is talking of becoming more energy independant. Solar, wind power etc. These are good things without a doubt. But you can do simple things at home to help reduce energy consumption. Low voltage lighting systems are excellent in producing more lumens (light output) per watt than standard 120 volt systems. That low voltage 50 watt MR16 lamp found in many recessed and track fixtures is lacking. Did you know you can replace it with a 37 watt MR16 and get the same amount of light? Less energy, same light. Sounds like a winner to me!
