A normal incandescent light bulb loses 90% of the power you put into it, in the form of heat (just touch a light bulb and see how hot it is). The cost of your solar energy system will depend considerably on the average energy consumption of your load. An important factor for all solar energy systems is the low energy consumption of these lamps compared to other light sources with the same brightness. These lamps also have an average life span of 10 years which is higher than an ordinary lamp.
