OBJEX LUMA-6CH lighting controller, a white DIN-rail module with screw terminals LUMA Smart lighting controller

Announced pre-order price: €149 + VAT

What it does

Your lights. Your network.
No one else's.

A controller for professional LED lighting. It handles monochrome, RGB, RGBW and Tunable White across six channels, with per-channel energy monitoring. It mounts on a DIN rail or hangs on a wall with the built-in keyhole. Everything runs on your local network: no cloud, no account, no app. A hardware secure element keeps your keys where they belong: on your device.

One controller, every setting

From interiors and offices to gardens, pools and hospitality, even on board: LUMA-6CH is at home wherever low-voltage light already works.

A living room lit by LUMA-6CH: warm cove light around the ceiling and downlights washing a wall
Hidden source · clean ceiling

Interiors

Cove and downlights on one device: the source stays out of sight, the ceiling stays clean.

An open-plan office at dusk lit by LUMA-6CH: linear LED runs across the ceiling over the desks, a warm wood wall to one side
Independent zones, one controller

Offices

Continuous ceiling runs: cooler, focused white over the desks, warmer over the lounge, two temperatures from one cabinet.

A hospitality lounge at dusk lit by LUMA-6CH: warm cove light tracing curved ceiling recesses, with lamps and a bar in warm white
Warm scenes, on cue

Hospitality & retail

Layered coves and lamps in warm white: each mood saved as a scene and recalled from a button or a schedule.

Garden steps at dusk, each tread underlined by a warm LED strip
Every tread lit, fixtures unseen

Gardens & paths

Steps and walkways with the strip recessed in the profile: you see the light, not the fixture.

A pool at dusk, its perimeter and submerged steps traced by warm LED strips
Integrated around the water

Pool & outdoors

Low-voltage perimeter light recessed in the coping: clean around the water, controlled from the browser at luma.local.

A sailboat deck at dusk, the companionway steps edge-lit by white LED strips
Driven from the battery bank

On board

Boats already run on DC: deck and cabin strips driven straight from the battery bank.

** DALI, KNX and the sub-GHz radio run on the engineering samples today. Whether they stay in the version we take through certification is still an open decision: the waiting-list form asks you directly, and those answers are what decides it.

How it works

Local by default.

The whole interface is a browser dashboard at luma.local. No app on every phone, no account to create, nothing in the cloud.

LUMA setup wizard at luma.local: Welcome to LUMA, get started in a few steps
Setup wizard

From box to first light

Power it and open luma.local: the wizard walks you through name, Wi-Fi and light layout in four steps. No app, no account.

Channel setup at luma.local: strip type per channel, mono, RGB and RGBW layouts
Auto-detect

It reads the load

On setup it pulses each channel and recognises the light type on its own: mono, RGB, RGBW, Tunable White or addressable.

LUMA dashboard at luma.local: one tile per channel, an RGB group lit in violet at 82%, monos in amber, live draw in watts
Channels

Every channel, one screen

The dashboard lines up one tile per channel, RGB groups included, each in its live colour: state, brightness and the real current draw in watts. Because it meters every channel, a failing strip or a miswired run shows up as a number, not a mystery. One tap switches it, one tap opens the detail.

Channel control at luma.local: power button, colour and brightness of an RGB strip, in the browser
Control

Colour, effects, brightness. Live.

One tap turns a light on. The detail view holds colour, white balance, effects and the dimmer; every change applies instantly, from any browser on your network.

Automation at luma.local: scenario list with triggers, run buttons and enable toggles
Automation

Scenes that live on the device

Scenarios run on the controller, not in the cloud: an external rocker or push-button, a door sensor, motion, or a calendar (time of day, days of the week, specific dates) can drive any light or group. Enable, disable or run them with one tap.

Energy pricing at luma.local: live cost estimate per hour, today and this month, with the monthly kWh history
Energy

It knows what it costs

Set your tariff once: LUMA-6CH turns real measured draw into cost per hour, today and this month, with a 12-month history stored on the device.

Backup and restore at luma.local: export the full configuration as JSON, import it, or factory reset
Backup

The whole setup is one file

Export the full configuration as JSON: name, layout, channels, scenarios. Restore it after a swap, or copy it to the next LUMA-6CH in minutes.

Waiting list

First in line when pre-orders open.

LUMA-6CH is going through CE certification. Pre-orders open in a few weeks and distribution runs between the end of 2026 and the beginning of 2027. The announced pre-order price is €149 + VAT. Leave your email and we will let you know the moment they open: nothing else.

The questions below serve our certification work and the assessments that feed the final industrialization of the product. We read them in aggregate: they tell us how to build LUMA-6CH, not who you are.

Double opt-in: you will get one email to confirm your address. No tracking, no third parties in your browser, data stored in the EU. Already on the list and changed your mind? Remove your email address.

FAQ

Questions, answered.

When can I get one?

Pre-orders open in a few weeks. Distribution runs between the end of 2026 and the beginning of 2027*, once CE certification is complete. Join the waiting list and we will write to you the moment pre-orders open.

* Small shifts in the delivery window are possible; the exact dates will be confirmed when pre-orders open.

Does it need the cloud, an app or an account?

No. You set it up from the browser at luma.local, on your local network: no app to install, no account to create, no cloud. If the internet goes down, your lights keep working.

Which lights can it drive?

Mono, Tunable White, RGB, RGBW and addressable LED, at 12-24V DC: 6 power channels (up to 180W each, 500W total) plus 2 data channels for addressable strips. There are also two inputs for wall rocker switches: the lights stay controllable from a plain switch, even with no network at all.

Does it integrate with Home Assistant or Node-RED?

Yes, that is the point of local-first. LUMA-6CH exposes open APIs on your local network: over Wi-Fi it talks to the systems that, like it, keep your data at home, Home Assistant and Node-RED first of all, plus the external BLE sensors made by OBJEX LABS. With open, local APIs, what you build around it is up to you.

Will it comply with the Cyber Resilience Act (CRA)?

Yes, it is designed for it. The hardware carries a dedicated crypto IC and secure boot, so the device only runs signed firmware. Updates arrive over the air from our servers, official firmware only, and you decide when to update. Telemetry is opt-in: you have full control over what the device shares with us to help us improve the product.

What am I committing to by joining the waiting list?

Nothing. You get one email to confirm your address and one when pre-orders open. No payment, no obligation to buy, and you can remove yourself at any time.

Tech deep-dive

From here down, it gets technical.

This section brings together results from the development testing of LUMA-6CH, along with a closer look at the hardware that brought the product to this stage.

It is for those who want to go deeper into the project, its performance, and how the hardware has evolved during development. None of the information below is required to choose, purchase, or install LUMA-6CH.

The figures shown here come from the units and configurations used during testing and may differ from the final production values. Final specifications will be provided in the official product documentation.
