Figure 1Figure 3Here’s some really basic info to help get you started.

The general term applied to fluorescent lamps that are single-ended and have bent, smaller diameter tubes is compact or compact fluorescent lamps (CFL). Some CFLs have integral ballasts and a medium or candelabra screw base for easy replacement of incandescent lamps.

Let’s begin with the easy one - integrally ballasted (or self-ballasted) compact fluorescent lamps are used to replace incandescent lamps. They screw into a socket that would otherwise use an incandescent lamp. (AKA ‘A’ style lamp or candelabra base, you know, Thomas Edison…)

DOUBLE TWIN-TUBE
For commercial purposes, we use a 4-pin based lamp. These will use an electronic ballast. There are such things as 2-pins lamps out there, but Title 24 prohibits the use of them, so act like they don’t exist :o)

Some manufacturers have their own names for CF lamps, see below for a helpful chart:

Osram-Sylvania’s new electrodeless lamps caught my eye. Apparently, they released the product over a year ago, according to a press release issued by OSI.

Electrodeless fluorescent lamps, commonly know as induction lamps, offer longer life over standard fluorescent technology. For more information about this technology, see the Licoda.com article, How Induction Lighting Works.
