English
A Scandinavian mountain cabin at dusk. In a whitewashed corner fireplace, four short logs stand in a tipi and glow warm orange from a light hidden in the centre log. There is no flame.

Real wood.
Living light.

LumaLog is a real wood log with a warm light hidden inside. Stand it with your other logs and an unused fireplace glows like a fire, with no flame, no heat and no cables.

Fire: a natural, warm glow with the odd flare.

Flame lamps look fine until you see the lamp.

Three logs lying on a black grate in a fireplace, glowing warm from behind. One of them is a LumaLog.
Can you see the lamp? It's the pine log at the back: its light points at the wall, so all you see is the glow.

Most fireplace lights are a bulb or a screen sitting between the logs, and your eye goes straight to it. LumaLog hides the light inside a log and aims it at everything around it: the other logs, the hearth floor and the back wall.

What you see is warm light moving over real surfaces, the way a fire actually looks.

One log in the stack does the work.

Three logs lean against the sooty brick wall of a cold fireplace. In the middle, the birch LumaLog throws warm light onto the logs beside it, the wall behind and the hearth floor. There is no flame.
Stand LumaLog among your other logs. The light lands on them, not on you.

  • A real log

    It's cut from real wood and hollowed out from the back. From the front it's just one more log in the stack.

  • Light you don't see

    Up to six light zones point at the logs around it and at the hearth floor, so the glow moves across real wood and brick instead of shining at you.

  • No flame, no heat, no cables

    A rechargeable battery sits inside, charged over USB-C. Switch it on with the button on the back, or from your phone.

  • A fire that doesn't loop

    The flicker is modelled on a real fire: a slow swell, a quicker flicker and the odd flare that rolls along the log. It never repeats in a pattern you can spot.

Turn it around.

From the front it's an ordinary log with its bark on. The light, the battery and the controller sit together in the LumaCore, in the back under a frosted cover.

The flat back of a birch LumaLog, seen straight on. A frosted cover over the LumaCore, held by two small black screws, closes the channel, with a status light, a button and a USB-C port near its lower end, above the burned-in LumaLog name.

Set the mood from your phone.

The LumaLog app connects to your log over Bluetooth. No account, no hub.

  • Three modes

    Fire for most evenings, Ember for a low glow and Flame for a big room.

  • Brightness

    From a faint glow up to full, in small steps.

  • Light zones

    Turn zones on or off, including two low ones that light the hearth floor.

  • Auto-off

    It switches itself off after anything from 30 minutes to 8 hours.

  • The sound of a fire

    Your phone can play a real crackling fire along with the light.

  • More than one log

    Keep the living-room log and the cabin log in the same app, each with its own name and sound.

You don't need the app. The button on the log switches it on and steps through Fire, Ember and Flame, and it remembers the last mode you used.

The LumaLog app with the fire lit: a live preview of the fireplace, the Fire, Ember and Flame modes, brightness at 60% and auto-off after 4 hours. The LumaLog app with the fire lit: a live preview of the fireplace, the Fire, Ember and Flame modes, brightness at 60% and auto-off after 4 hours.

Questions

What will it cost?

We haven't set a price yet. People on the waitlist will hear it first.

When can I buy one?

We're building and testing prototypes now. We'll email the waitlist when orders open.

How long does the battery last?

We're measuring that on the prototypes and will publish real numbers, not estimates. It charges over USB-C.

Does it get warm?

No. It gives off light, not heat.

Do I need the app?

No. The button on the log turns it on and steps through the modes. The app adds brightness, light zones, the timer and the fire sound.

Where does it ship?

We haven't decided yet. Join the waitlist wherever you are. Where people sign up helps us decide where to start.
