Does anyone have some nice, reliable information on the wavelength of the sensor? What range does it detect normally?

I am trying to build a modified, projected sensor bar.

My issue is that my TV is quite simply too big. If the sensor bar is at the bottom of the TV, my hand needs to be facing 20 degrees down from level. If its at the top, I get no reception at all (I think the wiimote may have some kind of filter to knock out ceiling lights by not picking up if its rotated too high, or perhaps something else?).

Regardless, I wish to make a sensor bar for the center of my screen, by using IR LED Lasers. The only problem is I don't know what wavelengths are acceptable, and IR lasers are a bit expensive (35$ for one).

I found the wiki saying it is 940nm, but cannot find any LED lasers under 100mW at that wavelength. Obviously, 100mW will burn a hole in my screen, so that is a no-no. <5mW should be just fine, as its not visible.
