Fiat Lux LLC

Fiat Lux LLC (Fiat Lux Division) is a Lafayette, Colorado-based limited liability partnership that conducts federally funded research in plasma physics and tokamak science as a grant recipient under the Department of Energy Office of Science. The vendor operates exclusively as a prime recipient on federal grants, with no contract prime footprint and no subcontract work in the source data.

Fiat Lux's entire federal award portfolio consists of three grants awarded by the Department of Energy Office of Science under CFDA 81.049 (Office of Science Financial Assistance Program). The research portfolio centers on tokamak plasma behavior, disruption mitigation, and extended magnetohydrodynamics (MHD) modeling. Representative grants include a $264,453.70 project grant awarded September 1, 2026, to model plasma response to non-axisymmetric magnetic field perturbations in tokamak boundaries, with performance through August 31, 2027, in Lafayette, Colorado; a $292,000 cooperative agreement awarded March 1, 2026, supporting tokamak research toward solving the disruption mitigation runaway electron gap, with work conducted in San Diego, California, through February 28, 2027; and a project grant awarded September 1, 2023, for extended-MHD atomic-physics research into DIII-D regimes without edge localized modes (ELMs), running through August 31, 2027.

Customer concentration is absolute — the Department of Energy Office of Science accounts for 100% of the vendor's award footprint. Combined obligated dollars across all three awards total $1.3 million. All three grants reach ultimate completion within the next twenty-four months, placing the full current portfolio at recompete cliff. Activity in the source data spans 2023 to 2026, with one award in 2023 and two in 2026. This is a research-stage vendor without contract or subcontract experience in the federal space.
