Thanks
The 940nm refers to the wavelength of the IR LED and not the size. I tried getting clear LEDs as per the instructions but Jaycar at Underwood in Brisbane only had blue coloured ones. I asked what the difference was and all I got was a shrug of the shoulders and a "I don't know." from the salesman.

I took the risk of spending $2.50 on the blue ones and they worked with my Pentax. I still don't know what the difference is except the colour of the plastic!! I suspect they would work with a Canon as well. The big thing is making sure you know which is the positive and which is the negative lead on the diodes. I was told the long lead was the positive one.

The 5mm is the physical size of the LED.

I hope this helps,

Cheers,
Mario
