what i heard&found (i did a presentation in class about environmental friendly lighting)
LED have efficiency of 25% (it still warm/hot though if you turn it on the whole day, e.g. check the display samples at ikea stores), fluorescence lamps 4-5%, incandescence bulbs are electric heaters which emit some lights
