A lot of bad talk about this company who actually is great. I've been working with many great brands such as Hella, Lightforce, NBB, Rigid Industries and Vision X.
And this is absolutely quality stuff and is not mediocre! The quality is far better than Hella, Lightforce and NBB, and I would rank them even with Rigid Industries in quality terms which I'm also a huge fan of.
Regarding the euro beam as we call it here in Europe is what you call driving beam in the states. It's a type of beam pattern that adds width to your lightning but tries to retain some throw by only spreading the light horizontal.
I have the Light Cannon here in my hand and this is what the euro beam looks like:
This is unfiltered (it's exactly the same output as Olight SR95, 90mm reflector and SST-90):
Regarding the snap-on filters which I believe Lightforce invented, is great feature. Instead of having to buy a new light if you wasn't satisfied with the beam pattern you can just change it.
I do however agree with you that colored filters are absolute crap, and this is where you guys hung up. I do testing of all my lights and I find blue to be annoying in snow and yellow also irritating. However it's somewhat true that the absolute white (~5500K) reflects most back into your eyes on snow but I still find using this color temperature most useful.
Here's some pictures in snow:
Vision X Horizon Prime 24" 90w (Cree XP-G) 10 degree
Vision X EVO Prime (Cree XM-L) 20" 120w 20 degree:
20" 60w (Cree XB-D) LED bar (no name) ~7000K:
Also a video of my car in snowy weather (3x 90w Vision X Transporter + 240w Cree XB-D no name LED bar):
