3. it's just a jumper.

thanks for the info so far,

I dont have a schem.

1)the capasitor, is the value to be calculated, kind as uou calculate theresistor? this as I found a online calc. for LED resistors ?

2) if this is the resistor, it is printed on there T680 so would that be 68 ohms? ore with the online calculator I can calculate hat I need

3) as you mention, a jumper, dous this not matter what ore how much .... (in other words it would have bin a little cable to jump ?

the online calc. I mention is:

http://led.linear1.org/led.wiz

so supply with 24V
forward volt CREE = 3.4
forward curent 800
number of LED 7

answer would be 1 ohms right ?
