I want to make a led glue stick lamp but i want it to power from 220-240v ac. See link https://www.youtube.com/watch?v=faNXVuPnZIE As all time 9v battery will be costly for me so i want to do this.

  • \$\begingroup\$ if you don't care about flicker, you can just use a series resistor. a capacitive dropper would provide smoother output. \$\endgroup\$ – dandavis Aug 9 '17 at 17:44
  • \$\begingroup\$ Bro i don,t know about the flicker, series resistor or capacitive dropper can you please explain me. \$\endgroup\$ – Rishabh Patel Aug 10 '17 at 15:13

I would assume that from the lack of information in your question, your electronics knowledge and experience is currently limited?

If this is the case please dont 'play' with 220VAC

I would suggest finding a suitable mains-powered 'wall wart' power supply. You should be able to use any one which gives sufficient current and voltage for your LED setup - and where you dont have 9V from the adapter you can change the resistor values to suit - many many free calculators for LED / Resistor online :)
