Compact fluorescents are full spectrum fluorescent lamps that have been shaped in a spiral so that they will fit in the same space as an incandescent light bulb but use only a fraction of the electricity. They have a standard screw base that will fit any ordinary light socket. Since AviLux compacts are true fluorescent lamps, they generate beneficial UV just like large fluorescent tubes. Compact fluorescents give you the convenience of a light bulb with all of the benefits of true full-spectrum lighting and extra savings on your electric bill.
