Two-pin Triple turn CFLs use the GX24d-1/2/3 fitting.

2D lamps use either the GR8 (2-pin) or GR10q (4-pin) connector.
Step 3 - Select Your Wattage
Choosing the correct Wattage for your bulb is important. A Watt is a measurement of power, the higher the wattage - the more energy it uses to produce light. These days the wattage is no longer an indication of how bright a lamp will be with the birth of the energy saving lamp and even halogen lamps.

Step 4 - Choose your Finish
When you have the correct bulb - you may then have the option of selecting the finish to your bulb. The most common choices of finish are clear and pearl.
