Numbers, in plain English

Built to outlast
a long winter.

The same chassis. Different fires per charge, different ignition speeds, different ways back to full. Choose the tier that matches the way you live.

Ember Pen™ · removable laser core

One pen.
Many homes.

Every FireKeep laser is the same hardened pen module — twist a tail-cap, press a latch, and it slides free. Use it docked in a flashlight body, a trekking-pole grip, or a knife pommel for maximum reach. Use it standalone, in your bare hand, when you want absolute aim on a piece of wet tinder.

  • Beam always exits forward and away from your hand and body — never down at your feet, never across your grip.
  • The pen runs on its own 21700 cell. Pop it out, light a fire, slide it back.
  • Same OD4+ glasses cover every host. Same interlock keys. One safety doctrine.

The fire we keep

Fire was the
first technology.

The thing humans guarded. Passed on. Refused to let die. We are not making a gadget — we are making the next way to keep that flame, one that runs on sunlight and lasts a season in your pack.

Common questions

Before you buy.

Where can FireKeep ship?+

USA + Canada at launch (Q3 2026), in jurisdictions where Class IV laser products are permitted. Excluded at launch: California, New York, Massachusetts, Australia, Germany, China, UK.

Can a colour matter for fire-starting?+

Yes — and that’s why we don’t sell colours that can’t. Both options (445 nm Signal Blue and 462 nm Glacier Cyan) sit in the wavelength range that ignites tinder reliably. We don’t sell green, red, or violet — they make pretty beams but won’t light a fire.

Do I need any training?+

Every unit ships with OD4+ safety glasses and an illustrated quick-start. The interlock keys must be inserted before the unit will fire — by design. Read the safety card before first use.

When does my order ship?+

Beacon-line pre-orders ship in their stated quarter (Q3/Q4 2026). Companion line follows in 2027. We hold a serial number for you in order of payment. Pre-orders are refundable.

Why does FireKeep use Sanwu Lasers as the OEM?+

Sanwu Lasers are the world’s most respected portable laser builder — they make the laser modules at the heart of every FireKeep unit. We don’t hide that. We integrate their best-in-class diodes into a FireKeep-engineered chassis with FDA-compliant interlock, serial registration, OD4+ glasses, and our brand promise behind it.
