How about Farnell 1045460 ?

Those should be OK Steve or 5mm std green ones from Maplin.

5mm std green ones from Maplin.

These are what I used.
Maplin have quite a range of green ones.
Just pick one that has a quoted Vf of 2.5V.
These work out to have Vf approx 1.9V at 1mA.


Jim.

I am ordering some other stuff from Farnell anyway. I thought I would go for 3mm to save a bit of space. Thanks for the tip.

I could see that would be an issue....
