I think it is because of the 440nm problem, the 440nm is very strong, as well as the spectrum which is below 440nm (which we don't use so far). And as long as the light use the real 440nm, and as long as there is the lens, the lens will sooner or later get dark, no matter how good the lens quality is. In order to change this situation, we upgrated our Mars pro series to be the lights without any lens on it, so there won't be any problem like this happen on our new lights.
I think my boss just have this thought, and see if you guys are interested to get the old lights replaced to our new Mars pro, but the detailed policy hasn't come out yet. so we need your kind and reasonable input. What's your idea?
