FAQ:

Q: What does a “self-ballasted” led mean?

A: What is a self ballasted light bulb? The term “self-ballasted” simply means that the bulb doesn’t require a ballast to manage the electricity flow. Self-ballasted CFL lightbulbs are self-contained and can be screwed in like traditional incandescent bulbs.

Q: What exactly is A GU24 base bulb?

A: The GU24 is a t-pin socket, usually containing two pins at the bottom that you line up with the base of the lighting fixture, twist, and then click into place. The Medium Base Socket, or Edison Screw, is threaded so a simple screw motion is required to get one in place.

Q: What is a fluorescent light ballast?

A: Fluorescent light ballasts are the devices which run fluorescent lighting systems. They start the lamp and keep it operating through the proper application of the voltages and maintaining the life of the lamp. It’s typically located in the center of the light fixture under a metal cover.

Q: What is electrical ballast?

A: An electrical ballast is a device placed in line with the load to limit the amount of current in an electrical circuit. It may be a fixed or variable resistor.
