MESHLE Bluetooth Mesh · Tunable White

Human-Centric Lighting Driver

A human centric lighting driver that shifts your luminaires from warm to cool white across the day for circadian comfort. This isolated constant-current, tunable white LED driver has MESHLE Bluetooth Mesh built in, so schedules and astro timing run locally on the device with no hub or cloud required.

Why this driver

Circadian tunable white, built on MESHLE Bluetooth Mesh

Tunable white for human-centric lighting

Two-channel warm-plus-cool output lets your luminaires move from energizing cool white to relaxing warm white through the day. Set up to 8 schedules per day or anchor transitions to local sunrise and sunset for true circadian lighting.

Offline-first MESHLE Bluetooth Mesh, built in

The mesh module is inside the driver — no separate node, no hub, no cloud needed for local control. Every node relays for its neighbors in a self-healing mesh, and schedules persist on the device even when no phone is connected.

NFC programming, flicker-free, DC emergency

Program output current and behavior over NFC for fast, precise commissioning on the line. The driver runs flicker-free across its full range and supports DC emergency operation for compliant installations.

MESHLE App

Intuitive Color Temperature Control

Every MESHLE device with the CCT Interface lets you adjust the color temperature across the full warm-to-cool white spectrum. Use the color ring to find the exact tone you need — from cozy warm white for relaxation to energizing cool white for focused work.

Combine color temperature with brightness control for the perfect atmosphere. The app adapts its interface to your device — showing exactly the controls your hardware supports.

Where it fits

Human-centric lighting for every space

Offices & workplaces

Drive tunable white downlights and recessed panels with a circadian rhythm — cooler, brighter light for focus in the morning, warmer tones toward the end of the day to support wellbeing and reduce eye strain.

Schools & education

Tunable white troffers and ceiling panels in classrooms shift color temperature to match the learning task and time of day, helping concentration during lessons and calmer light for quieter activities.

Healthcare & eldercare

Tunable white downlights and panels in wards, corridors, and care rooms follow a gentle warm-to-cool cycle that supports residents' circadian rhythm and gives staff the light levels they need around the clock.

Hospitality

Tunable white pendants and downlights in lobbies, restaurants, and guest rooms set the mood from bright and welcoming by day to warm and intimate at night, all scheduled to run automatically on the local mesh.

Retail & commercial

Tunable white spotlights and ceiling panels keep merchandise looking its best and adjust color temperature through trading hours, with circadian transitions running locally — no cloud connection to maintain.

Questions & answers

Human centric lighting driver FAQ

What is a human centric lighting driver?

A human centric lighting driver powers a tunable white luminaire and shifts its color temperature from warm to cool across the day to support people's natural circadian rhythm. This MESHLE driver is a constant-current, two-channel tunable white driver that handles both the power and the automated color-temperature transitions.

Does it need a hub or internet connection?

No. MESHLE is offline-first. The Bluetooth Mesh module is built into the driver, and schedules and astro timing are stored and executed locally on the device, so circadian lighting runs without any hub, gateway, or cloud connection. You can add a MESHLE Gateway later if you want remote access or smart-home integration.

What kind of luminaires can it drive?

It is a constant-current driver, so it pairs with bare two-channel tunable white LED engines — downlights, recessed panels, troffers, pendants, battens, and COB or linear engines that expect a regulated current. It is not designed to drive constant-voltage LED tape or strip; those need a constant-voltage controller instead.

How is the color temperature scheduled?

Through the free MESHLE App. You can set up to 8 schedules per day, each assignable to specific weekdays, triggered either by a fixed time or by local sunrise and sunset with a configurable offset. Once saved, the transitions run locally on the driver — no phone or internet needed.

What is NFC programming for?

NFC lets you set the driver's output current and configure its behavior quickly and precisely, including during production. It is a fast way to commission units on the line before the luminaire is even powered up.

Is it dimmable and flicker-free?

Yes. The driver supports smooth dimming and tunable white control over MESHLE Bluetooth Mesh, and it operates flicker-free across its full output range. It also supports DC emergency operation.

Who makes this driver?

The hardware is manufactured by CUPOWER, an isolated constant-current tunable white LED driver. MESHLE provides the embedded Bluetooth Mesh layer, the free MESHLE App, and the offline-first control, scheduling, and circadian automation.

Can it combine with MESHLE Swarm?

Yes. Because the driver outputs tunable white, it can run human-centric lighting on top of MESHLE Swarm: Swarm decides how bright each luminaire should be based on presence, while HCL decides the color temperature. Both layers coexist on the same mesh.
