But I think you're wrong if you believe that the heat given off by a lightbulb means you can reduce the output from your heating by anything near a corresponding amount. It creates a local hot-spot around the bulb and much of the heat energy would go into keeping that little area hotter than the rest of the room rather than dissipating evenly in a useful way. Room heaters either need to be big and near the floor, or have a fan or parabolic mirror to project their heat. -- TH * http://www.realh.co.uk
