What Prometheus Lights does

Prometheus Lights is a small-batch EDC (everyday carry) gear manufacturer founded in 2011 by Jason Hui, operating from a single California shop in Mountain View with a focused team of eight employees. The company designs, machines, and assembles all products domestically, combining CNC machining and Markforged industrial 3D printing to produce premium flashlights, writing instruments, keychain hardware, spin tops, magnets, and indoor lighting. Its engineering center of gravity is thermal and LED performance: the Alpha and Delta lines exclusively use Panasonic PGS graphite thermal interface material (six times the conductivity of copper) and Direct Thermal Path MCPCB LED mounting, paired with the proprietary Icarus programmable driver delivering 3.4A regulated current. The Ultra-High CRI LED bulb line uses a 15-step R1-R15 measurement (versus the industry-standard 8-step CRI), and select flashlights are tested to 300 feet submersion and 3-meter drop survival.

The portfolio operates across two main consumer brands: Prometheus (Alpha, Beta, Delta, plus Blue Label custom drops and Prometheans exclusive editions) at premium price points from $145 to $900+, and the acquired Foursevens brand (Quark MKIII, Mini/Turbo MKIII, Preon MKIII, Maelstrom MXS/MX3F) at more accessible $65-$185 tiers. Adjacent categories include the Alpha Executive Pen and Bamboo Fountain Pen (with fully interchangeable parts), the Kappa Quick Release keychain system (the company's best-selling SKU with 261 reviews), Lambda spin tops, Helix Keychain Fobs (including a Tec Accessories Embrite Glow variant), Psi titanium earplugs, and the SORAA-integrated Task Master Mini task light.

The business model is exclusively direct-to-consumer e-commerce through darksucks.com, with no retail, wholesale, or marketplace channels. Curated Blue Label and Prometheans mailing lists create scarcity around limited drops, while the site organizes SKUs into 15 lifestyle collections to drive organic SEO and use-case targeting. The company is founder-owned, has never raised institutional capital, and reports a 60% customer return rate (triple industry average), indicating a profitable, durable lifestyle brand serving EDC enthusiasts, professionals, and high-CRI lighting seekers rather than enterprise accounts.

Core offering

Prometheus Lights designs, manufactures, and sells premium everyday carry (EDC) flashlights, writing instruments, quick-release keychain systems, spin tops, keychain fobs, earplugs, and indoor high-CRI LED lighting directly to consumers via darksucks.com. All products are designed and produced in small batches in their California shop using precision CNC machining, Markforged 3D printing, proprietary thermal management systems, and premium materials including CP2 and 6Al/4V titanium, brass, and copper. The portfolio is split between the premium Prometheus brand (Alpha, Delta, Beta series) and the more accessible Foursevens brand (Quark, Mini/Turbo, Preon, Maelstrom), supplemented by limited Blue Label custom drops and Prometheans special editions.

Product overview

Prometheus Lights is a small-batch EDC (everyday carry) gear manufacturer operating out of California with a team of eight. The portfolio centers on two flagship flashlight lines: the Prometheus brand (Alpha, Alpha Shorty, Beta, Delta) offering premium custom-grade flashlights with best-in-class thermal engineering, High CRI LEDs, and extreme durability ratings (up to 300 ft submersion); and the Foursevens brand (Quark MKIII, Mini/Turbo MKIII, Preon MKIII, Maelstrom) providing more accessible but still high-quality flashlights with consistent UI and 80+ CRI standards. Beyond flashlights, Prometheus offers the Alpha Executive Pen and Alpha Bamboo Fountain Pen (both launched via Kickstarter, with fully interchangeable parts), the Kappa Quick Release keychain system (the company's best-selling product), Lambda spin tops (the original ruby-tipped fidget tops), Helix Keychain Fobs, Psi Earplugs, and Fridge/Shop Magnets. Indoor lighting is served through the Task Master Mini (High CRI task light using SORAA bulbs and 3D-printed components) and a line of Ultra-High CRI (95+) LED bulbs (A60 and A19 Filament) using the extended 15-step R1-R15 CRI measurement. Two limited-release programs — Blue Label (custom flashlights) and Prometheans Drops (exclusive special editions) — serve collectors and enthusiasts. All products emphasize domestic manufacturing, premium materials (titanium, brass, copper), and engineering transparency.
