[WiiFlash] Wii sensor bar IR leds best specifics ?

[Cedric M. analogdesign]

Hello everyone,

This is my first post on this list.

I'm currently preparing my order of electronic components to build a custom
Wii sensor bar.

I just have an hesitation about IR leds and which one is better...
Here's the list of which Leds I may order:

20mA, 940nm, angle 50° 
20mA, 880nm, angle 50° 
20mA, 940nm, angle 30° 
20mA, 880nm, angle 30° 


Do you know which are the characteristics of the IR leds into the original
Nintendo Wii sensor bar?
Do the ten leds share the same characteristics? 
Which one did you use for your sensor bar?


Thank you in advance for your piece of advice on the point based on your own
experience.


Best regards.
