Wanted to post here in this thread, I just got my M30Cvn w/ 219b sw45ks and this light ROCKS. I think it's well worth the money, with White 2 this is surely a crazy light! The beam is pretty unreal, even white-wall hunting once you are past 5 feet or so, it's almost impossible to tell this is a triple reflector light.
VN4+ Eagtac build = no brainer. Great size, solid quality, very nice light. In the end I don't think the price detracts too much from it, sure I'll always take it cheaper, but it's worth it!
I have a little test I do with all my thrower lights by bringing them into work with me. My studio is in a warehouse, which are BRUTAL on flashlights, warehouses suck up all the light, and the dim ambient light being everywhere makes things extra screwy trying to judge your lights in one. Even some of my more impressive throwers have the wind taken from their sails- super intense but small hotspots are taken advantage of. Granted this is highly subjective, but its an interesting metric to me nevertheless.
The M30Cvn manages to be a light that performs
very well in a warehouse, even with the lower output of the 219b emitters. With the White 2mm, I imagine it would be a fantastic user, and I'm heavily considering one now.....
Another thing to note, it provides just over ANSI 1000lm with the diffuser installed, and a SUPER awesome beam that manages to still be punchy but an even diffusion out to the edges.
This is definitely an R ladies and gentlemen, I think everyone should pick their favorite emitter and get one of these lights with them. I bet the SST-20 3000K would be a super awesome setup in this host.
