  • Received four of these little critters the other day, and tested them out, using the camera on my iPhone 3G. I observed that two of them lit up very dimly compared to the others. Then I tried the camera on my other phone, an iPhone 4. Now they all lit up brightly. Two of them were even visible with the naked eye, giving off a very weak red color. So there clearly is a difference in the wavelengths of the IR LED's. The datasheet for the IR LED states that the minimum wavelength is 940, and the maximum 950 nm, so I guess that's the explanation.

No public wish lists :(
