could anyone tell me what should be the value of a resistance for a high intensity LED? i'm going to use to light a few acrylic panels in my install.

thanks for your help.

huh? what do acrylic panels have to do with the resistance of an LED?

LEDs do not have a specific resistance, they are non-linear devices.

ohh wait i reread that you want the resistor to put in series with the LED? how much current can it handle?

if you are going to wire up some LED's on 12 volt--depending on the voltage each requires - thats what determines you resistance.  if you have LED's that require 3.3-3.5v you'd need about a 330 ohm resistor to run them on 12 volts. Here is a link to a resistance calc..........http://www.ledsupply.com/reca.html.......just cut/paste...and when you calculate 12v, you should really up it to around 13.4.

thanks a million! i should have been more specific, yes, I used a 330 ohm resistor, it worked out grand. I'll post some pics when I'm done!!
