Fluorescent tube lighting. Fluorescent tube lighting is an example of how to wire a fluorescent tube lamp with an electronic ballast (choke). Electronic chokes do not need a starter, offer instant startup, flicker-free operation, and conservation of energy. The AC line is connected to the electronic ballast input, and the tube lamp is directly connected to the output terminals. Neutral to the other end of the tube lamp. Proper wiring will ensure safe operation, eliminate flickering, increase the life of the tube, and minimize the use of energy. Electronic chokes, unlike magnetic chokes, are electronically regulated, also they do not need a starter. The process of testing is based on starting the tube, making sure that a glow occurs immediately without flickering, and that the brightness remains constant. This type of wiring is common in residential, commercial, and industrial lighting, where efficient lighting energy is used and long-life lighting is needed.

Work & Installation (Input → Output Summary)

AC Supply (Line & Neutral) connects to the electronic ballast input.
Electronic Choke (Ballast) regulates current and provides instant startup.
Tube Lamp connects to the output terminals of the electronic choke.
Neutral connects to the other terminal of the tube lamp.
On powering ON, the tube lamp glows instantly without flickering.
Electronic choke maintains stable current, ensuring long tube life and energy efficiency.

Testing & Final Adjustments

Verify line and neutral connections to the electronic choke and tube lamp.
Switch ON the power; the tube lamp should start instantly without flickering.
Inspect the electronic choke for overheating during operation.
Check multiple ON/OFF cycles to ensure consistent performance.
Ensure wiring terminals are secure and insulated.
Confirm stable brightness of the fluorescent tube.
Replace tube or ballast if flicker or dimming occurs.
Ensure compliance with electrical safety standards.
Verify correct polarity and connections of the tube lamp to the ballast output.
Record observations for maintenance and operational documentation.

Frequently Asked Questions - Lighting Contactor Wiring Diagram:

What is an electronic choke?

An electronic ballast that regulates current to a fluorescent tube and provides instant startup.

Does it need a starter?

No, electronic chokes eliminate the need for a starter.

How is the tube lamp wired?

Line to electronic choke input, output to one tube terminal, neutral to other terminal.

Is flickering normal?

No, electronic chokes provide flicker-free operation.

Can I use it for 2ft or 4ft tubes?

Yes, using the appropriately rated electronic ballast.

Is earthing required?

Yes, for metal fixtures and safety compliance.

Can electronic chokes save energy?

Yes, they are more energy-efficient than magnetic ballasts.

How to test wiring?

Switch ON power and ensure instant, stable glow of the tube.

Does it increase tube life?

Yes, stable current and instant start reduce wear and flickering.

Can multiple tubes use one electronic choke?

No, each tube should have its own properly rated electronic ballast.
