CFL vs. INCANDESCENT BULBS. Incandescent bulbs lose energy in the form of heat. CFL bulbs lose very little energy through heat and thus consume less power. Tip: Energy savings ratings will vary from manufacturer to manufacturer. Since CFL bulbs do not produce heat, you will also save on cooling costs. In an incandescent bulb, electric current heats a filament to the point that it glows.
