We don’t build gear to sell.
We build gear to carry.

Most companies build for a market. We build for ourselves, then make enough for you. We’re a team of eight who carry our own gear every single day—because if it isn’t good enough for our pockets, it isn’t good enough for yours.

Prometheus Flashlights

Jason Hui
Owner & Founder

made by people : made for people

we are our own toughest customers

I started Prometheus alone in 2011, designing gear I actually used. As demand grew, so did the pressure—and by 2017, I brought on my first two full-time teammates, Joy and Gilbert. We're now a focused team of eight, still small but committed to excellence.

We don’t just make products—we rely on them. I don't trust any product made by someone who doesn't use it. That’s the difference. I’ve visited top brands where not even the owner uses their own gear. Around here, if it’s not in our pockets, it doesn’t go out the door. With 15 years of industry experience and customer feedback, we don't guess at what works, we know.

The Legacy: We took a legendary brand and rebuilt it around our philosophy. Customizable, modular, small-batch production that focuses on perfecting the "classics" for everyday carry.

Quark QK16L MKIII

$95.00

"I work in QC at a Honda supplier parts plant. I use my Quark, almost every night, inspecting parts; porosity, casting damage, Machining damage, etc. Love the hi-low beam option. Bullet-proof construction, pocket clip-always on my shirt. Tremendous tool. Thank you!!"

Maelstrom MXS "Standby"

$185.00

“This is my fifth purchase. Two were gifts for family and I kept three - I got them over time and they're strategically placed (for family here here). Mine woke me up when a fire fried the power lines. I am glad I did not sleep through that one. This light is another layer of defense/safety. It has fine performance."

The Lab: This is our sandbox. 100% designed and machined in our California shop. Experimental, high-end, and pushed to the limit of what’s possible in design, CNC, and 3D printing.

Kappa Quick Release

$19-$70

“This is the best quick-release keychain I’ve ever had. I previously had a magnetic one that would frequently disconnect by accident, and the Kappa has held everything together so nicely. It’s also way smaller than my old keychain, so to be really honest, I barely notice that it’s there. I love it so much :) It’s also developed a super nice patina."

Alpha Flashlights

$335-$900

“Before I bit the bullet on the carbon I had previously purchased a ready made and a custom. All serve there purposes but the carbon is a beauty! The triple Nichia gives you some extra power but still get the high color rendering. The carbon fiber sleeve feels great in the hand and the glow effect around the LEDs creates a nice effect. Fit and finish is perfect."
