Wow, you are really start to accuse people once one thing pops up in a sec... They are led, so the wavelength could differ slightly from one to another. Have you tried e- mailing them, a forum is not the best, or good way of communication. If they did/ have not answered, then It is possible I guess. From the amount of people that trust them, I would not think they are trying to hide anything in specific.
@smitty06 I didn't mean it to be 'that' harsh. Yes I tried via other channels to get this info. I own a Ray 2DS. So it's not like I don't have any trust in them. However---- knowing the wave length the unit puts out is important.
