Also beware relections from your IR source. The distance depends on which IR tracker you use. I assume the 4 LED tracker with your planned purchase. It is not always easy to say whether it will work at 3m, as there is no exact formula for this. As a backup plan, you can also make a 3d print that uses a lens.

Yes, I was thinking about getting a wide lens as well to have that backup.

Of the different models they had in that shop, I had in mind the wireless one pictured. The main doubt is that on the official Lichtknarre site they mention to use 3W LEDs and the ones in these units seem quite below that. By reading about standard LEDs the 3 of the small ones might have a combined output of 0.2W or so.

Wondering if this product then is totally worthless and better to not even try buying that model.
I've not seen a good one yet powerful and with large cables for large screens yet.

Fusselkroete:
I would suggest the cable version. if the cables are too short you can increase yourself.

The thing is, the higher the watts, the more the LEDs can stand out from reflections/sunlight etc.. But the normal Wii remote bar only has so few watts. With the LK-software, you just have to make sure that it doesn't get confused, as the wii remote can only evaluate 4 IR light sources. Higher watts makes it more easy for the software because you can decrease the sensitivity. But the IRs can also produce reflections and they are brighter with higher watt leds aswell. Selfmade IR-Emissions, natural IR emissions, IR emission from other devices.

The official website only mention the 3w as a suggestion since the author made this as a hobbyproject and can't evaluate every situation if it is realy worth to use these bright IR-LEDs. Also the author don't use the original nm wavelength from the official wii remote bar aswell. I would suggest stick to official wavelength since nintendo designed the wii remote in junction to the ir-bars.

The author shouldn't be such a lazy one not to adjust the documentation -.-.
