SupBeam X60vn at 6,430 lumens and incredible throw of 433 kcd. You can try contacting rdrfronty - maybe he is willing to part with it. Not sure if vinh would have one available immediately.
This is a stock X60 modified heavily to increase output. Beamshots here: https://budgetlightforum.com/t/-/23557.
Your best chance is to try to find a heavily modded light made by someone here and make an offer. There are "brighter" customized lights around here that are higher lumens than the X60vn - I'd say 8,000+ lumens, but very rare.
