LED in Coin Door
SirPeale:
Should I be using a 5mm or a 10mm LED in my coin door?
SirPeale:
All right, here's another question.

This is the LED I'm thinking about using.
According to the LED Calculator I downloaded from http://www.gideontech.com/articles/led_calc/ I would need a 1690 ohm resistor.
Not knowing anything about LEDs, the exabyte site mentions forward and reverse voltage. What exactly is that?
Also, I'm getting wildly varying values when I put in current values. When I put in 20ma, I get a resistor rating of 1590, but 50 gets me 569. How do I know what to use?

This response always comes up when someone asks this question, and I know this isn't the answer you were looking for either... but have you thought about the wedge-base LED's that are available? They're already "resistorized" and run off 12-volts.

I think TazMan used them in his cab and they plugged right into the sockets on his coin door.

I have seen them, but the coin doors I have don't have the wedge bulbs, they slide into a socket, and then turn to lock.

Well, I figured my post would be about worthless. Actually, the lights in my coin door are the same type as yours. They make some LEDs like that too, but I'm not sure they're small enough or inexpensive enough for our coin doors.
