How to Change 2 Pin Fluorescent Light Bulb? [2022]

If your home was built before 1985, there’s a good chance you have one or more fluorescent light bulbs with two pins rather than newly arrived smart bulbs. These bulbs are being phased out, but you don’t have to wait for them to die to switch to a newer type of bulb. Here’s how to change a 2-pin fluorescent light bulb.

               1. Turn the power off. This is important because it will prevent electrical shock. If you can, disconnect the switch that controls this light so that no one can turn it on while you are working on this project.

               2. Remove the bulb socket. The socket is attached to the light above the fluorescent tube itself. To remove it, simply turn it counterclockwise until it comes free. Most sockets have a tab or notch on the side that you can use to grip with your fingers for turning, but be careful not to break the plastic socket off of the light housing.

               3. Pull out old bulb. Once you’ve removed the socket, pull out the old bulb and discard properly. Most fluorescent bulbs are not designed to be used more than once or twice, so if it’s burned out then don’t bother trying to plug another one in–you’ll just end up burning both bulbs out before too long.

               4. Put new bulb into socket. Insert the new bulb into the socket and turn clockwise until it is secure.

               5. Replace socket. Push the socket back into place until it locks securely, then turn it clockwise to turn the power on. There are no special precautions needed for this type of bulb since they don’t contain any mercury, so you can keep using them as long as they work properly without replacing them if one dies early.

               6. Turn power back on. Once you have replaced the bulb and the socket, change the switch so that this light turns off with all other lights in your home or office building. Depending on your wiring configuration, your old two-pin bulbs may end up turning all other lights in your house off whenever this one goes out–and vice versa–so make sure you do this step.

Why you need to change pins of fluorescent light bulb?

There are different types of light bulb in the market. One of them is fluorescent light bulb. It works by passing electricity through a tube filled with mercury vapor and argon gas to produce ultraviolet light that causes the phosphor coating on the inside of the tube to glow. Fluorescent lamps are more economical than incandescent lamps because they do not consume as much power, but it has high failure rate due to its manufacturing process.

When you are trying to change 2 pin fluorescent light bulb, make sure you turn off your power source before starting work or even replacing bulbs. The reason why you need to turn off current is because when electricity flows through 2 pin fluorescent light bulb, voltage will pass from one end of glass tubing where cathode (-) is located to other end where anode (+) aluminum cap is located. Electricity will start a process called electrolysis that dissolves glass from both ends of tube allowing electricity to go through it resulting in heating up the gas inside. Because of this reason 2 pin fluorescent light bulb contains mercury and it can be dangerous if you touch mercury with bare skin.

Frequently Asked Questions:

1. What tools do I need to change a 2 pin fluorescent light bulb?

You will need standard screwdriver and medium strength plumbing tape.

2. What is difference between normal and compact fluorescent light bulbs?

Normal: Normal ones aren’t as energy efficient, but they last far longer than the compact variety which saves you money in the long run because you don’t have to change them as often (meaning fewer fumes). Compact: These are better for small spaces such as desk lamps, since the tube itself is smaller and lighter weight than a regular fluorescent bulb. They’re also more energy-efficient, reducing electric bills without significantly reducing brightness.

3. How do I dispose of old 2 pin fluorescent light bulbs?

You should always handle fluorescent bulbs carefully, even when they’re turned off. Fluorescent bulbs contain a layer of gas that can be harmful if it is exposed to air (for instance, if the tube breaks). Stick to this general rule: If you’ve had a fluorescent bulb in your possession for more than two minutes, it should be recycled. Discard old 2 pin fluorescent light bulb by contacting your city or county government about recycling programs in your area.

4. Is there a trick to changing fluorescent light bulbs?

No, there is no “trick” to changing a light bulb. If you have a fluorescent light fixture in your office or home, it will contain a light switch somewhere along the line to allow you to cycle through different lights within your environment if one burns out. The only additional hint I would provide is this: If you have metal halide or high-intensity discharge lights installed as a primary source of light, you should consult with a licensed electrician to do the job. Fluorescent fixtures are for work areas and not capable of providing enough wattage to operate these more intense types of lamps.

5. How do you change a fluorescent light bulb under cabinet?

Turn off the power to the lamp and remove the glass dome. Unscrew the screw holding in place and pull out old bulb. Put a new bulb in and replace screw that holds in place. Then replace glass dome over top of light fixture.

6. What happens if you push a full fluorescent tube into a connector too far?

If you push in a full fluorescent tube to the point where it will not go any further, do not try to force it in–you will only damage the connector.


Fluorescent light bulbs are not designed to be used more than once or twice, so if it’s burned out then don’t bother trying to plug another one in–you’ll just end up burning both bulbs out before too long. Also, we have discussed some of the cool steps and methods that you can use change a 2-pin fluorescent bulb. Make sure to follow the exact steps mentioned above to avoid any kind of harm.
