Someone asked me recently “What is a CFL bulb? What does the CFL mean?” so below is a short description in reply to this question.
CFL is short for Compact Fluorscent Lamp. CFL lamps are a type of energy saving bulb – they save money along with the added benefit of saving energy. CFL bulbs can replace incandescent bulbs and the wattage will be lower than the incandescent bulb you are replacing – this is how the saving is made.
In most cases the CFL will be more expensive than the incandescent bulb, but they last longer as well as saving on the energy usage side.
