LUMA-6CH / Development evidence

LUMA-6CH development testing and hardware evolution.

OBJEX LABS / 21 August 2026 / Revision 1

These results describe the units and configurations used during LUMA-6CH development. They document what we tested; they do not replace the specifications, certification or limits of the future commercial version.

Why publish development results?

Headline ratings state what a product should support. Development tests help reveal how electronics, firmware and thermal management behave when loads are sustained or temporarily exceed the rating. Limits matter too: passing a test above specification does not automatically make that load a guaranteed operating condition.

Development test results.

Test	Condition	Result	Outcome
Maximum continuous load	500 W combined, 25 °C	6 h continuous	PASS
Single-channel overload	200 W on one channel, 180 W rating	6 h continuous	PASS
Combined overload	600 W, 20% above rating	2 h continuous	PASS
Extreme overload	720 W, 44% above rating	3 h continuous	PASS*
Reverse voltage	Input polarity reversed	No damage	PASS
Shock and drop	Laboratory conditions	Operational afterwards	PASS
PWM resolution	500 Hz – 1 kHz	12-bit	PASS

* The 720 W test completed without failure, but this is not a rated output. Thermal improvements are planned before the commercial version's limits are defined and validated.

From concept board to V1.2 prototype.

The first board validated the local-control concept. Later revisions separated logic and power, allowing control, radios, security, outputs and thermal behaviour to be developed and verified independently.

LUMA V1.0 concept board — **V1.0 / Concept**The first board used to validate local control and the base architecture.

LUMA V1.1 prototype logic board — **V1.1 / Logic**Controller, radios and secure element move to a dedicated logic board.

LUMA V1.1 prototype power board — **V1.1 / Power**Six PWM outputs and two data ports are developed separately.

LUMA V1.2 logic board — **V1.2 / Logic**Revised logic layout for the current development platform.

LUMA V1.2 power board — **V1.2 / Power**The revision used for the load tests reported in this article.

A real installation problem shaped the functions.

LUMA began with lighting inside the OBJEX LABS laboratory: some areas were too bright, others insufficient, and light needed to adapt to workbench activities. Early revisions explored timed and conditional sequences, routine-based automation, per-channel energy measurement, physical-control inputs and local integrations. These trials describe the development path; availability and status of each function must be checked on the current product page.

Evolution also includes installation format.

The first board was intended for a generic enclosure. The current mechanical direction is a four-module DIN-rail device with an alternative keyhole mount for a wall or service space. This choice connects PCB, terminals, wiring, heat flow and maintenance to the real installation context.

How to read these results.

These are development observations, not independent certifications. Full conditions, instruments and procedures will be consolidated in validation documentation. Always design an installation around the published rated limit: up to 180 W on an individual channel and 500 W combined, not the maximum reached during an overload test.
