The +30 comes in part from better focus. Improving the focus more would probably give us the +50 or +100.As technology evolves do you think we will see a super duper +30 version with even more focus? Vosla managed to improve on the 9012 and give the excellent +30 model they offer.
Or perhaps we can just get an offroad H9 with an IR coating
No. H9 already has all those "Plus" techniques built into it. It is a high-luminance, high-intensity, short-life light source.
