14 Watt => 15.75 watts actually! With a "focal chair PM230" (consumption meter) measured it from me. I had (with halogen bulb) installed a 116 watt light bulb at the same place and the difference is noticeable, but really small. I test the LED bulbs to since it exists and has always been very dissatisfied, this bulb meets my expectations really good. Add to this the energy saving and therefore cost savings. Buy recommendation !!!
