Good morning, I was browsing some schematics and saw one on your page about a LED Tube. I have a 20m LED tube and the controller has popped. It seems that the whole 20m tube runs on 220volts DC i tried to bypass the 4 transistors which where popped, but just ended up exploding the cap on the board. Is there a way that I can get these lights to work with some basic circuitry?

Thank you very much for your time

sir, can i connect half watt or 1 watt white LED for Tubelight circuit instead of regular 5mm LED. & Component are same or pls guide me for half /1 watt 230 volt circuit diagram,

NO 1 watt led cannot be run on 220volt AC without a Transformer, see my Project below......

24 LED of 1 watt on 220 volt AC

sir i have made 30 LED 5mm 230 volt tuble light circuit . its working ok but some LED flickering occurs. but its working ok. No any component heating , also same circuit with 14 LED built in Scrap CFL Bulb holder and its working ok . It running -25 days gone. but its working very good. and this circuit used in My Gods Temple. 24 Hrs it is On . No any problem. thanks sir.

can you please help me with diagram or pics, and help to calculate leds to be attached in series for 220 volts without using any transformer. i will be greatfull if you can draw a circut for it as i am totally new to this
Dipankar (author)  amehrotra22 years ago
See my Project SKYSCRAPER LAMP, you will find the Circuit, this is without Transformer.

can i use the above method for 130 LED's ? if yes, then what will be the value of the capacitor and the resistor?

For 130 LED's you need more than one Capacitor and Resistance. See my LED TUBE LIGHT.

Hi sir,

i m suresh From Satara Maharashtra. I read this artical, it awesome good. one query is how to fit LED /What type of base used.Can you show the picture of Assembly of Tube light , OR For Tube Light What type of Material used as base. Pls Send us Detail Circuit diagram & Assembly photo/any Idea . My mail ID Is .. sureshjpatil@gmail.com.

Sir: can you please tell me how i can use my sensor light w/c is 110vac here in Manila(220Vac) w/out using step down transformer (transformer consumes electricity even the unit is idle).

thanks, Romy Reyes Manila Phil. (mastering@fasdevcorp.com)
