Here’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:
