Introduction: LED TUBE LIGHT (AC)

About: Now I am a retired person, who enjoys life and making small things to pass the time keep myself busy.

My friend Justin, wanted my help to make a LED Tube Light, so this is the result for all of you to see.
The tube light is a row of LED's which runs on 110 or 220 volts AC, just like your ordinary Fluorescent Tube Light.

Step 1: STEP-1

List of parts required.
100 pieces or more of Very Bright White LED's of 5mm size.
1-or more Non Polarized Capacitor .33uF to .47uF rated 250v to 300 volts for ----110v AC
1-or more Non Polarized Capacitor .22 uF rated 400 volts -for 220 volts for AC
1 or more Resistance of 1k -1 watt for ----110v AC
1 or more Resistance of 1k - 1/2 watt for ----220v AC
2 inches width and 4 feet long PVC concealed wiring rigid batten.
On off Switch, wire, wall plug, solder etc.

Step 2: STEP-2

In this Step take a 2 inches width and 4 feet long PVC concealed wiring batten.
Fix two rows of 15+15 LED's at a gap of 1 inch.
This 30 LED make one segment.
Fix 3 SEGMENTS of 90 LED's as shown in the Photographs.
Follow the Circuit Diagram in detail.
The gap between the LED's should be 1 inch so as to cover the 4 feet of PVC batten.
The 3 segments should be connected in parallel to the house AC outlet. (110 volts)
Put an on-off switch before connecting to the house outlet.
Your Tube light is ready.
Switch it on and enjoy the soft light.

Step 3: STEP-3

This circuit is for them who have 220 volts AC as their house supply.
I added this step for them.

Sir, I cannot understand how this circuit is working without a d.c. current .

can you explain working principle and how voltage dividing?


What do you mean by '2 inches width and 4 feet long PVC concealed wiring rigid batten.'

I'm not sure what this is

sir i want the above mentioned pdf but when i am going to click for download it is asking me to upgrade for premium , how can i got that pdf sir

PDF download is only available to paid-up pro-Members.

Really I do not know, sorry.

Thnx for response. However, did not follow why flicker will increase. Can you pl explain the working?

2 replies

The shorter the distance of (plus)+ and (minus) - LED flicker is less, and the longer the distance the flicker is more.

I have a question. Why two LED's are connected back to back? (and such 15 pairs in series) If we connect 15 LDE's in series (all +ves in 1 direction) & another 15 LED's in series (all -ves in same direction) & and then connect these two rows in parallel, will it work?

YES....... it will work but the flicker will be more......

Hello sir,

can I bother you to help me make a circuit of 20 LED's 5630 which runs on AC 220V?

Thank you in advance

What is 5630? Please mention the size of the LED in mm. like 5mm,10mm.

What mm LED's you want to use?

can you share with me a circuit of 20 LED's 5630 which runs on AC 220V like twistedone78 ask to you?

Dear sir without filter capacitor it will not work smoothly so kindly add filter capacitor also

Not required, as it works on AC......

I want to make 96 led tube light.
Can you circuit diagram. My email id is ishwar.patil1980@gmail.com


I was going thru your post regarding 24 watt LED Lamp. I was looking for something like that but with fewer nos of 1W leds (around 10 - 12). I have a led driver with output ratings of (8-12)x1W, 320mA. Can u please help me out.. Can I use 8-12 leds directly with this driver or need to add some other components to it?

Yes you can use only one or two rows of LED's, see circuit below....


Thanks for the reply..
