Compact Fluorescent Light : CFL
Twin Tube - Have two parallel tubes in their form. Their uses are lamps, wall-mounted lights, recessed ceiling lights and rectangular style task lights. They find their way into household as well as industrial uses.
Quad Tube - Has four parallel tubes in their form. They essentially put out the same resources as the the Twin Tube, but are shorter, thus making them ideal for household style lamps and fixtures. Industrial uses could include office lighting and personal workspaces.
Spiral Lamp - Has a spiraled shape element to it's form. These lights, being similar to the older style incandescent light bulbs, have proven to be the best selling type of CFL sold today. It's this form that most people associate with the CFL and fluorescent lamp movement.
F Lamp - Has two sets of twin tubes in their form. These lamps are mostly used in commercial task lights and recessed fixtures. Homeowners might utilize them in their garages or shops.
Circular Lamp - Has a round element to it's form. Mostly used for reading lights, these circular CFL's also find uses in the medical field for focussed lighting.
Additionally, the CFL features these types of bases:
Screw Base - These are fluorescent lamps that have the old Edison style screw in socket. They mostly replace existing incandescent bulbs, making it simple to just swap the two out when replacement is required.
Pin Base - These CFl's have a smaller plastic base that has either two or four pins that plug in to ballast type fixtures.
GU24 - This is the latest in design for the CFL type lamp. It's intended to be Energy Star compliant and replace the old Edison style screw in bulb. It's common knowledge that this type of base is superior to the older and should become a standard very soon.
The Compact Fluorescent Lamp is an innovation as well as a practical product with many uses. There seems to be strong evidence that their adoption into the mainstream should produce many benefits worldwide.
