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

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

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?

YOU CAN GO ON ADDING SEGMENTS OF 30 LED's AS SHOWN IN THE DIAGRAM.

Dipankar (author)  panchavatik1 month ago

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

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)

You will have to use a 110v Transformer, there is no other way.......

Sir---

I FINALLY made it work using 4 leds---

NOT perfect--smoking resistor----but it WORKED---

A Loose Nut Behind the Soldering Iron May be the PROBLEM---

Thanks for YOUR TIME and EXPERIENCE

For 220volts use 0.22uf 400 volts
and for 110 volts use 0.47uf 250volts
Resistors in both cases use 1K/half watt.
