Maelstrom lights have seen many generations and iterations over years. They are Foursevens' brightest lights, but they are meant to get the job done, not to impress you friends.

We put a useful amount of power into a package that delivers run time, reliability, and usability without making any compromises.

Side switch lights have a dedicated UI that is simple, intuitive, and functional.
This is the first light from David Chow, the founder of Foursevens. It was also the first "high power" production LED flashlight ever created, when it was launched in 2009. If you ever wonder why the Quark looks like a lot of other flashlights, just flip that around. The Quark was first.

The original form factor of the Quark has been maintained for a decade, but the light has been continuously refined and updated. No other light on the market has this much experience in the field.

Today's Quark features the latest in LED technology that delivers unparalleled beam quality, and a host of accessories mean you can make the light work just like you want it to.

The Quark is a legend, pure and simple.
Mini/Turbo MKIII
The third generation Mini lights deliver compact power in two flavors. The Mini MKIII is for close to medium range use and the Mini Turbo MKIII employs a Cree XPL-HI LED and large reflector to deliver lumens at medium to long range.

The MKIII variants were updated with native 360 Headlamp compatibility, making the Mini series one of the most versatile EDC lights on the market. I also added a genuine Velcro hook pad to the base of the headlamp. Don't like head straps? Me neither. That's exactly why I had our own custom patch hats made.

If you are looking for versatility, look no further than Mini/Turbo MKIII.

Another third generation light from Foursevens, refined over time. Every iteration of the Preon made it better, and there is nothing left to improve.

MKIII Preons feature a 90+ CRI Nichia LED, a perfect pocket clip, and an new rubber button that won't activate by accident.

If you are looking for a 1 or 2 cell AAA light with a tailcap button...welcome home.

At Foursevens we know every customer and use case is different. You might even need one light to support multiple missions. That's exactly why we developed a range of accessories that allow you to personalize your lights and adapt them to your life.

We are constantly looking for ways to improve our lights and your experience. Drop us a line if you have a great idea.
