How to Change LED Tube Light Safely: Step-by-Step
How to change LED tube light fittings depends on which of three types you have. If it is a separate tube in a holder, switch off the MCB, rotate the tube 90 degrees, lower it out, and fit the new one the same way. If it is an integrated LED batten (tube and body as one unit, the most common type in Indian homes now), you replace the whole batten by unclipping it, disconnecting three wires and fixing the new one to the wall. If it is an old fluorescent fitting, a new LED tube may need the old choke and starter removed first, or it will flicker or fail. Identify your type before buying anything.
At a glance
You have | Looks like | What you replace | Time | Skill |
|---|---|---|---|---|
Integrated LED batten | One slim unit, no visible pins or end caps | Whole batten | 15 to 20 min | Basic wiring |
LED tube in a holder (T5 or T8) | Removable tube with pins at both ends | Tube only | 5 min | None |
Old fluorescent fitting (with choke and starter) | Bulky body, small round starter can | Tube, and remove or bypass choke and starter | 20 to 30 min | Basic wiring |
Identify your fitting first
Look at the ends of the light. A small round plug-in cylinder (the starter) or a heavy box inside the body (the choke, also called ballast) means it is an old fluorescent fitting. Pins at each end of the tube that sit in rotating sockets mean a replaceable tube. A single slim unit with no separate tube, often clipped onto two wall brackets, is an integrated batten.
Fitting | Pros | Cons |
|---|---|---|
Integrated LED batten | Cheapest overall, no choke, lightest load on inverter | Whole unit is thrown away when the driver fails |
Replaceable LED tube | Only the tube changes, quick | Fixture must be compatible; check the tube's type |
Retrofit LED tube in old fitting | Reuses the old body | Old choke wastes power and can cause flicker unless bypassed |
Safety first: before you touch any tube light
- Switch off the light at the wall, then switch off the MCB for that circuit at the distribution board. Our guide to MCB sizes explains which breaker does what.
- Confirm the power is off with a tester screwdriver on the wires.
- Let the old tube cool for a few minutes if it was on.
- Use a stable ladder, not a chair. Wear gloves and eye protection when handling old glass fluorescent tubes.
- Old fluorescent tubes contain mercury. Do not break them; keep them aside for proper e-waste disposal.
How to remove LED tube light from holder
Most tube holders in India use rotating "bi-pin" sockets.
Step 1: Hold the tube in the middle with both hands
Support its weight so it does not drop when it releases.
Step 2: Rotate the tube 90 degrees
Turn it a quarter turn in either direction. You will feel the pins line up with the slots in the sockets.
Step 3: Lower the tube out of the sockets
Gently pull the tube downward so the pins slide out of both sockets together.
Step 4: If it does not turn, check for a spring-loaded holder
Some holders are spring-loaded at one end instead. Push the tube towards that end to compress the spring, then swing the other end out. Do not force a stuck tube; old plastic sockets crack, and a cracked socket needs replacing.
How to change LED tube light: step by step
Step 1: Remove the old tube or batten
For a tube, use the removal steps above. For an integrated batten, slide or unclip it from its wall brackets, then note which wire goes to L (phase, usually red or brown), N (neutral, black or blue) and earth (green). Take a photo before disconnecting.
Step 2: For old fluorescent fittings, remove the starter and check the tube type
Twist the small starter anticlockwise and pull it out. Then read the new LED tube's box. A "plug-and-play" tube works with the old choke. A "ballast bypass" tube needs the choke disconnected and mains wired straight to the sockets, as the tube's diagram shows. Follow the diagram exactly, because a wrongly wired bypass tube can short.
Step 3: Fit the new tube or connect the new batten
For a tube, insert both pins into the sockets and rotate 90 degrees until it locks. For a batten, connect L, N and earth to the matching terminals and tighten the screws firmly. A loose terminal is a common cause of flicker.
Step 4: Fix it in place and test
Clip the batten onto its brackets or close the fitting cover. Switch the MCB back on, then the wall switch. The light should come on instantly with no flicker. If it flickers, see our guide on why LED lights flicker.
How to fix LED tube light on wall
Integrated battens come with two mounting clips and screws.
- Hold the batten at the planned position and mark the two clip positions with a pencil. Most battens are 2 ft or 4 ft; check that the clips align with the ends.
- Drill holes with a 6 mm masonry bit and insert wall plugs (gitti).
- Screw the clips to the wall, keeping them level. A spirit level or phone level app helps.
- Bring the supply wire through the clip area, connect L, N and earth at the batten's terminal block.
- Press or slide the batten into the clips until they click.
- On a false ceiling or wooden panel, use wood screws instead of wall plugs.
Mount the batten at least 15 to 20 cm below the ceiling where possible, so heat from the driver can escape.
The power and money math
Old fluorescent fittings use a 40 W tube plus a copper choke that itself wastes power (commonly around 10 W or more; varies by model). An equivalent LED batten draws about 18 to 20 W.
Fluorescent tube + choke | LED batten | |
|---|---|---|
Power draw | ~50 W | ~20 W |
Units in a year at 6 hours a day | ~110 units | ~44 units |
Yearly cost at ₹7 per unit | ~₹770 | ~₹307 |
Saving per tube per year | ~₹463 | |
Load on inverter during power cut | 50 W | 20 W |
Four tubes switched to LED save about ₹1,850 a year and cut 120 W from your inverter load, which stretches battery backup noticeably.

Should you do it yourself?
- Strong fit for DIY: replacing a tube in an existing LED holder, or swapping a batten for a new one using the same wires.
- Marginal fit: converting an old fluorescent fitting with a ballast-bypass tube. Doable if you follow the diagram, but take care.
- Not a fit: no earth wire, burnt or brittle wiring, aluminium wiring, or an MCB that keeps tripping. Call an electrician.
Conclusion
How to change LED tube light fittings safely comes down to three things: identify whether you have a tube, a batten or an old fluorescent fitting; switch off at the MCB and test before touching wires; and follow the removal and mounting steps for your type. Switching from a fluorescent tube to an LED batten saves about ₹460 a year per light and reduces inverter load. Browse the Adwin LED lighting range for replacements.
FAQs
How to change LED tube light without an electrician?
If you have a removable tube, switch off the MCB, rotate the tube 90 degrees, lower it out and insert the new one. For an integrated batten, disconnect phase, neutral and earth, connect the new batten the same way and clip it in. Call an electrician if wiring is damaged or there is no earth.
How to remove LED tube light from holder if it is stuck?
Rotate it a quarter turn firmly while holding the middle, then lower it out. If it will not turn, check for a spring-loaded holder and push the tube towards the spring end. Do not force it, because the plastic sockets can crack.
How to fix LED tube light on wall without drilling?
Some lightweight battens can be stuck with strong double-sided mounting tape on smooth tiles, but this is not recommended on painted walls or for long-term use. Screwed clips are the safe method. On a false ceiling, use wood screws.
Do I need to remove the choke when fitting an LED tube?
It depends on the tube. Plug-and-play tubes work with the old choke, while ballast-bypass tubes need the choke disconnected and mains wired straight to the sockets. Read the box and follow the wiring diagram.
Why is my new LED tube light not working?
Common causes are a starter still fitted, a ballast-bypass tube installed with the choke still connected, a tube not rotated fully into the sockets, or a loose terminal. Check each in turn with the power off.
Can I replace a fluorescent tube with an LED tube in the same fitting?
Yes, if the tube is compatible with your fitting. Many Indian homes find it simpler and cheaper to replace the whole fitting with an integrated LED batten, which removes the power-wasting choke.
How much electricity does an LED tube light save?
Replacing a fluorescent tube and choke drawing about 50 W with a 20 W LED batten saves about 66 units a year at 6 hours a day. At ₹7 a unit, that is about ₹460 a year per light.
Which wire is phase in a tube light connection?
In Indian wiring, phase is usually red or brown, neutral is black or blue, and earth is green or green-yellow. Colours are not always followed in older homes, so confirm with a tester.
