can we use resistor place of capacitor because i saw in led lamp circuit in that they using 6 2.2k resistor for blowing 30 led at 230 v ac 50 hz
sankarganesh am 18.09.2010 um 15:55 Uhr
your information is very nice.where to you use for LED light?how much range for capacitor used?
Prabhu am 31.08.2010 um 09:06 Uhr
I need to connect a led in series with the resistor. where the supply for that is an AC 230v. Which i'm using for this as an indication.

avinash am 14.07.2009 um 12:08 Uhr
i need a circuit that should work on 230v,for 15 - 20 LEDsalso the heat dissapation should be less.
supun am 22.04.2009 um 09:59 Uhr
Dear Sir,
Thank you for publish this circuit. what will happned,when we replace this LED to a 5colour LED, an add smoothing capcitor for it.
thank you.
