is IR and IRD the same.
I found at a local electronic stores this Led but I am not shure if there is a difference or if I can use them for making the Ir pen.

Based on the fact that the label says "infrared detector", I'd say those are phototransistors or photodiodes, not LEDs at all.

I looked up IRD-500 and those are detectors.

I also looked up TLN-100 (look on the bottom of the package "use with TLN-100".)  Those are the IR LED's.

I can't say if they are any good however.
Hope that helps.
