An incandescent bulb is 96% efficient as a heater, and 4% efficient as a source of light. A fluorescent bulb is only 60% efficient as a heater, and 40% efficient as a source of light. An LED bulb is only 10-20% efficient as a heater, and 80-90% efficient as a source of light (but that light is usually unidirectionally directed... harder to do diffuse lighting with them).
What are facts on the light bulb?
1 The light bulb was invented in 1879 by Thomas Alva Edison. 2 When you turn on a light bulb only 10 per cent of the electricity used is turned into light, the other 90 per cent is wasted as heat. 3 In the UK we waste £140 million a year by leaving our lights switched on unnecessarily - this causes 900,000 tonnes of CO2 emissions, enough to fill 180,000 hot air balloons! 4 Low energy light bulbs last on average up to 12 times longer than traditional fluorescent bulbs. 5 Each low energy light bulb you install in your home could save you as much as £9 per year in energy costs, or £100 over the bulb's lifetime 6If every UK household installed just three compact fluorescent light bulbs in place of traditional bulbs, enough energy would be saved in a year to supply all street lighting in the UK 7 UK households use £1.9 billion worth of electricity every year on lighting 8 Energy efficient bulbs last up to 12 times longer than their inefficient counterparts 9 A heavy coat of dust can block up to half of the light 10 If everyone installed one energy-saving light bulb the carbon dioxide emissions saved would fill the Royal Albert Hall nearly 2000 times. Hoped this helped! :)
